The 365 Days of Astronomy

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. [email protected]

The Actual Astronomy Podcast Episode 464 presents Observing Lists and Eyepiece Cleaning. In this episode we talk about a few observing lists Chris is working on for the RASC Observer's Handbook and Calendar plus some Wide Field Wonders.  Shane details his cleaning process for eyepieces.

My little counterweight arrived!

Bought a semi-truck snow brush to clear snow from the rails

Sadly where the roll off rails enter the observatory freezing rain and snow accumulate behind the wheels, builder can fix it but we need warmer weather.

A lot of folks wrote about why the 7-inch wasn’t up in the observatory…this is why since it eats up so much room it is difficult to work in there.

A couple notes on the RASC publications I’m involved with. Due to our postal strike here in Canada we have to delay giving out a copy of my RASC Observer’s Calendar which I edit each year. The good news if you are in the states there is a bundle sale for the Observer’s Calendar and Observer’s Handbook, $44 and with the exchange favouring our American friends it is nearly a buy one get one free situation.

Gravity has shaped our cosmos. Its attractive influence turned tiny variations in the amount of matter present in the early Universe into the sprawling strands of galaxies we see today. A new study using the first year of data from the Dark Energy Spectroscopic Instrument (DESI) has traced how this cosmic structure grew over the past 11 billion years, providing the most precise test to date of how gravity behaves at very large scales. In this podcast, Dr. Pauline Zarrout discusses these results and the future of DESI research.

Bios: Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona.

From 2015 to 2018, Pauline did her PhD at CEA-Saclay on the clustering analysis of eBOSS quasars. She is a laureate of the 2018 L'Oréal-Unesco fellowship For Women in Science. Then, she continued as a postdoctoral researcher in DESI at the ICC at Durham University. Since October 2020, she is a CNRS researcher in cosmology at LPNHE.

From Jun 22, 2021.

Minor planet 2014 UN271, discovered in data collected by the Dark Energy Survey, is set to make a close pass to Saturn’s orbit at the end of the decade, giving astronomers a chance to observe a rare trans-Neptunian object from up close...ish. Plus, Venus, Jupiter, the Milky Way, and an invisible galactic structure discovered quite by accident.

Andrew L. Chaikin (born June 24, 1956) is an American author, speaker and science journalist. He lives in Vermont. He is the author of A Man on the Moon, a detailed description of the Apollo missions to the Moon. This book formed the basis for From the Earth to the Moon, a 12-part HBO miniseries.

From 1999 to 2001, Chaikin served as executive editor for space and science at Space.com. From 2008 to 2011, he was a faculty member for Montana State University in Bozeman, Montana. In 2013, he wrote and performed the narration on a NASA video re-creating the taking of the famous Earthrise photo during the Apollo 8 mission.

His book A Man on the Moon: One Giant Leap states that he grew up in Great Neck, New York, and, while studying geology at Brown University, worked at the NASA/Caltech Jet Propulsion Laboratory on the Viking program.

Water for Martian Colonists!

Martian colonists will need to create mini environments with air to breathe and water to drink. Energy will be required to keep warm, power the settlement, and enable vehicles to move around the planet.

- Aug 6, 2024.

Recently my Catalina Sky Survey teammate Greg Leonard discovered, 2016 WJ1, a relatively large asteroid which can come close but will not hit the Earth. The extremely unlikely scenario of an impactor with our number on it would start the with the report of a fast moving point of light in the night sky. After a few days of data the Minor Planet Center would give it a name.

I’m Rob Webb, your Last Minute Astronomer, bringing astronomy to normies and nerds, with little time to spare. Joining me today is my son, Soccorso.

13th – 14th – Geminid Meteor Shower –  The Geminids are usually a good shower, with up to 100 meteors per hour.  That means that, even though this is not a great year for them (Full Moon will brighten the sky and reduce how many meteors we’ll see), hanging outside for 20-30 minutes should still bring you some good sights.

When? Really, any time of the night is good. After midnight is always best…

Where do I look? The whole sky, but note Gemini is where the radiant is - where the meteors will appear to be coming from. Gemini will be in the East after sunset, South after midnight, West in the morning.

But be well prepared…

• Dedicate at least 20-30 minutes to being outside and not looking at your phone - this allows your eyes to get dark adapted and reduces the risk of you missing one because you’re going in-and-out. Stay dark-adapted by staying away from light sources or using a red light if you need to look at a star chart or not trip over something.  
• Find a dark location and lie down in a reclining chair or hammock.
• Dress warmly. LAYERS!!!
• Check the weather to see if the skies will be clear.
• Adapt your eyes to the dark by staying away from light sources or using a red light if you need to look at a star chart or not trip over something.  
• You never know when a nice meteor will burn up, so take a nice look at the sky in general, noting that the meteors will appear to go from the radiant and outward.

Dec 6th Friday - Moment of Global Darkness occurs when 85% of the global population experience night simultaneously. 

According to Date & time .com Nighttime for Almost Everyone—How Is That Even Possible? Just like at any other moment, the Sun will illuminate one half of the globe on December 6 at 19:56 UTC. The other half will be dark, and people living there will experience nighttime.

The reason why so many people will be in darkness is that the world’s most populated areas will be on the night side of Earth at that moment. That includes nearly all of Asia, which is home to about 60 percent of all humans. Meanwhile, the Americas, New Zealand, and most of Australia will be bathed in sunlight. However, while being huge landmasses, relatively few people live there. North and South America combined only make up about 13 percent of our worldwide population.

Last week we talked about the Einstein probe. So this week it is only natural that we talk about the man himself, Albert Einstein. He revolutionized the field of physics, played a vital role in the early 20th century and struggled to unite the forces of the Universe at the end of his career.

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- Jul 16, 2024.

My Catalina Sky Survey teammate Carson Fuls discovered 2015 TC25 as a rapidly moving point of light in the night sky. Followup observations using data from four different telescopes has enabled a team of astronomers led by Dr. Vishnu Reddy of the University of Arizona's Lunar and Planetary Laboratory to determine that this small asteroid reflects four times more of the sunlight than do most other Earth approaching asteroids. Dr. Reddy points out that large asteroids are covered by a blanket of dust but that "Small asteroids might be bald and dust free." This team of researchers found the surface of Carson's discovery to be similar to a small meteorite which fell to Earth in France in 1836.

- Jul 23, 2024.

Dangerous Asteroids Are Still Out There! Recently my Catalina Sky Survey teammate Greg Leonard discovered a rapidly moving point of light in the night sky. Subsequent observations made by telescopes in Arizona, Romania, Illinois, the Czech Republic, Australia, and France revealed it to be a close approaching Potentially Hazardous Asteroid. The Minor Planet Center named it 2016 WJ1. This asteroid is about 200 yards in diameter, orbits the Sun once every 567 days, and currently can come to within about 26,000 miles of the Earth's surface. 2016 WJ1's orbit eventually will bring it near Mars, Earth, our Moon, and Venus. Any of these encounters have the potential to change it's path around the Sun.

Next steps, if we don’t trip first.

Hosted by Steve Nerlich.

Dear Cheap Astronomy – How will we find the first evidence of extra-terrestrial life?

Well of course, we don’t know – the question is more invitation to review the various options and rank the relative likelihood of those options based on the information we have to hand. So - it’s possible that we’ll first find evidence of intelligent life in the form of an electromagnetic signal of technological origin coming from another star system.

Dear Cheap Astronomy – Are we safe from asteroid impacts now?

No, but we are safer. The recent DART mission showed that you can divert the trajectory of an asteroid by impacting it with a fast moving spacecraft. The 2022 DART mission demonstrated that the DART spacecraft’s kamikaze crash moved the asteroid Dimorphous by some tens of metres. Tens of metres won’t save Earth from a collision with an object that’s already closing in – but from sufficient distance such fractional shift could very well modify its trajectory so that it misses.

Hosted by Loretta Cannon for the AAS-HAD.

Today’s guest: Dr. Linda Spilker (JPL Fellow and Sr Research Scientist: https://science.jpl.nasa.gov/people/Spilker/ ) talks to us about the Voyager mission. She was there for the launch and each planetary flyby!

H’ad astra historia is the official podcast for the Historical Astronomy Division of the American Astronomical Society.  We’re here to share stories from and about the people who study the stars, planets, and the cosmos.  We’ll be hearing from individuals who not only study the history of astronomy, but also those who lived it, who were “in the room” during pivotal events within the last 50 years or so.  

Loretta Cannon (an AAS affiliate via Rose City Astronomers) is a science-and-word-nerd who really likes the stars. She quite enjoys working as HAD’s podcaster, bringing astronomy stories to you.

- NASA’s Voyager HOME page: https://science.nasa.gov/mission/voyager

- Voyager Mission Overview: https://science.nasa.gov/mission/voyager/mission-overview/

- Voyager Mission Status: https://science.nasa.gov/mission/voyager/where-are-voyager-1-and-voyager-2-now/ This page has a table that shows (in real time) elapsed mission time and the distance each spacecraft has traveled (distance from Earth or the Sun).  During the Spring (for folks in the northern hemisphere) the distance from Earth will be decreasing; this is normal because the Earth moves around the Sun each year.  

- Voyager as seen in NASA’s Eyes on the Solar System:

https://eyes.nasa.gov/apps/solar-system/#/sc_voyager_1

This page is a real treat!  You can ‘see’ the spacecraft’s location in real time, or you can move it backwards to watch its travels since 1977, and so much more.

From Aug 30, 2023.

TRAPPIST-1 has held our attention for a long time because it has so many rocky worlds orbiting a star that may allow some of them to have liquid water. The promise of life is too great to ignore, so we turn our most powerful telescopes to this system whenever possible.

Now there’s been a new system on the block. The Transiting Exoplanet Survey Satellite, or TESS, has brought us the discovery of a system that is every bit as interesting as TRAPPIST-1.

From January 9, 2009.

As astronomers discovered that we live in a great big universe, they considered a fundamental question: is the Universe the same everywhere? Imagine if gravity was stronger billions of light years away… Or in the past. It sounds like a simple question, but the answer has been tricky to unravel.

Today's 2 topics:

- My Catalina Sky Survey teammate Josh Hogan was asteroid hunting in the constellation Sextans with our 60 inch telescope on Mt. Lemmon, Arizona when he discovered the largest asteroid in nearly a decade. 2023 HQ2 is its name.

- The natural night sky is alive with its own lights. In addition to celestial sources often there is natural night sky airglow powered by space weather from above and/or tropospheric activity from below. It is not the Aurora Borealis. Amazing images show green airglow waves which are brighter than the Milky Way.The theory behind these beautiful images remains a mystery.

Practically speaking.

Hosted by the ever practical Steve Nerlich.

Dear Cheap Astronomy – Is in situ resource utilization really worth the trouble?

Here at Cheap Astronomy we tend to say disparaging things about in-situ resource utilization, but usually in response to suggestions that if we want to land on Mars all we have to do is make rocket fuel out of in situ resources to take off again. While ostensibly true, a substantial amount of infrastructure would be needed to both source and refine the ingredients to make that fuel and you’d probably want to experiment with a few different methods, expect a few false starts and have a few trial runs before you’d actually put people on your launch vehicle.

Dear Cheap Astronomy – What exactly is the space economy?

The Space Economy is defined by the OECD as the full range of activities that create value and benefits to human beings in the course of exploring, researching, understanding, managing, and utilising space. As we’ve previously discussed both on this and the fabulous Science on the ISS podcast, exploring, researching and understanding space are important activities– but if we are really going to move forward, more of the managing and utilizing space need to come into play.

- Phil Plait, known as “The Bad Astronomer,” ( https://badastronomy.beehiiv.com ) discusses his journey in science outreach, from debunking astronomy myths to writing popular books and consulting for science fiction.

- He emphasizes the importance of reconnecting people with the wonder of the night sky, combating the disconnection caused by light pollution and digital media.

From  Aug 29, 2023.

Hosted by Tony Darnell.

This planet was discovered in August 2006 by the Trans-Atlantic Exoplanet Survey.  It became the very first planet observed by the Kepler Space Telescope with the designation Kepler-1b.

Kepler-1b is a gas giant that is slightly larger than Jupiter and has one and a half times its mass, but orbits much closer to its star than Mercury does to our Sun. It takes only 2.5 days to complete one orbit, meaning that its year is very short. It also rotates synchronously with its star, meaning that one side always faces the star and the other side always faces away. This creates a huge temperature difference between the day and night sides, which can reach up to 1,500 degrees Celsius.

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- In less than two hours my Catalina Sky Survey teammate Allesandra Serrano discovered two small fast moving space rocks. Both of them passed through the Earth-Moon system unimpeded. Other space rocks are not so lucky.

- An object like 2023 MN5 impacts Earth once every 90,000 years or so creating a crater 5 miles in diameter an 1800 feet deep in sedimentary rock. 50 miles from the impact of such an object observers would feel the effects of a 7.1 Richter scale Earth. Rest assured that asteroid hunters will continue to track 2023 MN5 as it passes near Earth and Jupiter to make sure that its orbit does not change to make it a threat to humanity.

Observations using the Dark Energy Camera (DECam) confirm astronomers’ expectation that early-Universe quasars formed in regions of space densely populated with companion galaxies. DECam’s exceptionally wide field of view and special filters played a crucial role in reaching this conclusion, and the observations reveal why previous studies seeking to characterize the density of early-Universe quasar neighborhoods have yielded conflicting results. In this podcast, Dr. Trysten Lambert discusses how DECam enabled astronomers to reach this conclusion.

Bios:

Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona.

Dr. Trystan Lambert’s research career has focused exclusively on extragalactic observational astronomy, exploring both low and high redshift regimes. During his M.Sc. at the University of Cape Town in South Africa, he contributed to the completion of the 2MASS Redshift Survey and developed the galaxy group catalog. He then moved to Chile, where he pursued my Ph.D. at Universidad Diego Portales, studying galaxies and quasars in the epoch of reionization using ALMA and DECam.

Dr. Lambert  is currently a Research Associate at the International Centre for Radio Astronomy Research. He spends his days developing tools to identify large-scale structures in redshift surveys, particularly in the Wide Area VISTA Extragalactic Survey (WAVES). Identifying these large-scale structures allows us to map the distribution of dark matter in the local universe and provides a crucial test bed for current cosmological theories.

The Most Efficient Propulsion System Out There

From  May 15, 2018.

People always ask me why we’re stuck with chemical rockets. Seriously, exploding a bunch of hydrogen or kerosene is the best we can do? 

Good news, there are other, exotic science fiction-sounding propulsion systems out there which use electromagnetic fields to accelerate atoms, allowing their spacecraft to accelerate for months at a time. 

I’m talking about ion engines, of course, and several spacecraft have already used these exotic thrusters to perform some of the most amazing missions in the exploration of the Solar System.

Today's 2 topics:

- Hungarian astronomer and geography teacher Krisztián Sárneczky was asteroid hunting in the constellation of Lynx with 0.6m (24 inch) telescope at the Piszkéstető station in the Mátra Mountains when an unknown object streaked through a set of his images. It is the 7th such object to be tracked in outer space and then observed to enter our atmosphere. A tiny asteroid the size of 2023 CX1 enters the Earth’s atmosphere about once a month and gives asteroid hunters a chance to practice for a big one.

- Carson Fuls, one of my Catalina Sky Survey teammates, is leading the effort that will allow you to join our NASA funded adventure in asteroid hunting and discovery. You will learn how to scan our nightly archival images to discover new small solar system worlds.Happy asteroid hunting.

I’m Rob Webb, your Last Minute Astronomer, bringing astronomy to normies and nerds, with little time to spare.  Let’s start by talking about the naked eye planets visible this month, the lunar phases, and then the meteor shower and other events, so you can plan further ahead than me. 

Similar to October, in November Saturn and Jupiter are the steady highlights above, Venus shines brilliantly after sunset, and rocks fall from the sky.

A highlight:

17th - 18th – Leonid Meteor Shower – This annual, weak (10-15 per hour) meteor shower can have some wonderful years.  This year is good because the waxing crescent Moon will already be set early in the evening, making it clear of lunar light pollution into the morning, the best time to view it.

Some advice for watching: 

• Find a dark location and lie down in a reclining chair or hammock
• Look around Leo’s head.  That is where the radiant is - where the meteors will appear to be coming from. 
• The strategy to observe this year is to get out there whenever you can, but the later you stay up, the more you’ll see, since the radiant will be higher and you’ll be closer to the peak.  
• Check the weather to see if the skies will be clear 
• Adapt your eyes to the dark by staying away from light sources or using a red light if you need to look at a star chart or not trip over something.  
• You never know when a nice meteor will burn up, to take a nice look at the sky in general, noting that the meteors will appear to go from the radiant in the head of Leo and outward.

George’s Random Astronomical Object presents HD 11397. This Sun-like star might seem ordinary, but it actually contains abnormally large amounts of heavy elements, most notably barium, that it could not have formed itself.

Brief biography: Dr. George Bendo is an astronomer who specializes in studying interstellar dust and star formation in nearby galaxies.  He currently works at the Jodrell Bank Centre for Astrophysics at the University of Manchester, and his primary role is to support other astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA).  He has been creating biweekly episodes of George’s Random Astronomical Object since 2019.

Ralph Wilkins hosts. 

Damien Phillips, John Wildridge and Dustin Ruoff produce.

From Oct 21, 2022.

This show is all about Betelgeuse and supernovas (supernovae? Let's call the whole thing off). What will happen to Betelgeuse? How bright will it get? When will it go supernova? Will we get to see it? How do we predict supernovas?

A new study points to a rapid dimming (like the one we saw in 2019!) just before it obliterates itself in a violent release of energy that will make it brighter than anything else in the night sky.

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- Project Breakthrough Listen is spending $100 million over 10 years so that radio telescopes can search for signals which may indicate extraterrestrial intelligence.In a recent article in the Astronomical Journal a team of astronomers published a paper entitled “A 4–8 GHz Galactic Center Search for Periodic Technosignatures”. The teams first effort yielded a null result, however, they plan to continue to search for rotating beacons which could be used by extraterrestrials to communicate with far flung regions of the Milky Way.

- An extremely wide field of view camera, the Zwicky Transient Facility, operated by Caltech on Palomar Mountain in California is able to take images of the entire northern sky every couple of days. This capability has enabled to astronomers to find nearly 8,000, Type IA supernova. A recent discovery SN Zwicky is unique.

Part 3 – SKAO Construction Commencement Ceremony

In the third and final part of the SKAO Construction Commencement Ceremony series, Jacinta sits down with Professor Phil Diamond, the Director-General of the SKAO to discuss his thoughts and feelings around the construction commencement ceremony in Australia and on the future of the project as a whole.

Professor Phil Diamond has been a strong supporter of the SKA (Square Kilometre Array) since it was first proposed in the early 1990s and officially joined the project in October 2012. He has led the project through its various design stages up until this point where construction is finally commencing.

In this episode, Prof. Diamond shares his experiences with the site selection, his thoughts on the commencement ceremony as well as insights into the intricate design of the “Christmas tree” antennas of the SKA-Low Telescope. Join us for this behind-the-scenes look at the SKA project!

Dr. Holbrook (Harvard Smithsonian Ctr. for Astrophysics, Univ. of Edinburgh, Univ of the Western Cape) continues with her story of the AAS’ Astronomy Oral History Project. You’ll learn about her favorite interviews, and she gives me some advice for future podcast episodes. 

H’ad astra historia is the official podcast for the Historical Astronomy Division of the American Astronomical Society.  We’re here to share stories from and about the people who study the stars, planets, and the cosmos. We’ll be hearing from individuals who not only study the history of astronomy, but also those who lived it, who were “in the room” during pivotal events within the last 50 years or so.

Robots Like Us...

Implausible Engineering – Episode 2a: Brain in a robot

In a step towards technoevolution and potential immortality that some future generation of humanity will develop the ability to transfer their brains into robot bodies and hence have prolonged if not immortal lives. Various complications arise in trying to engineer this. Assuming you have all the vital veins and arteries attached to tubes which feeds a nutrient solution in and out with some kind of hemoglobin carrier in it that donates oxygen and removes carbon dioxide – all you are really doing is replacing the life support systems previously provided by a human body. But your brain is still a brain.

Implausible Engineering – Episode 2b: Evolving into robots

As we like to discuss on Cheap Astronomy us humans, like the dinosaurs and the trilobites and the blue-green algae are just steps in a meandering evolutionary pathway to nowhere particular. It’s not like the blue-green algae, trilobites or dinosaurs ever aspired to be something better, it’s just that some individuals with certain traits were more successful than others so they had more progeny and so on.

Most of the 5,000 exoplanets discovered so far have been found using methods that don’t actually see the planet at all.  Brightness dimmings and star wobbles only get us so far. They limit our ability to study them in detail and astronomers are working on gigantic starshades to resolve planets directly!

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- Atira, named for the Pawnee goddess of Earth and the Morning and Evening Star orbits the Sun inside of our path. Atira, the first of this type of asteroid, was discovered by the Lincoln Near-Earth Asteroid Research Program using telescopes in New Mexico. Atira is a stony object more than a mile in diameter, spins on it's axis of rotation once every three hours, has an irregular shape, and orbits the Sun once every 233 days. This asteroid was named Atira who is a goddess of the Native American Pawnee tribe. She is the wife of the creator god, Tirawa [Tire a wa]. She is the goddess of Earth and the Morning and Evening star.

- Should martian microbes be sacrificed to human space exploration?

It is unlikely that any living organism could survive being blasted from the surface of a planet, travel through interstellar space on a meteoroid, survive a fiery entry through another planet's atmosphere, and be viable when it reaches the surface. However, humans are breaching this interplanetary barrier. We have robots operating and are planning to land colonists on the red planet. This situation has prompted doctoral student Daniel Helman of Prescott College to ask the question "If Martian microbial life is discovered, is it ethical for humans to colonize Mars even if that means spoiling the environment of the microbes?"

Welcome to episode 135 of George’s Random Astronomical Object, or, if you prefer Roman numerals, episode CXXXV. Every episode, I run a random number generator to select random astronomical coordinates in the sky, and I then search for an astronomical object near those coordinates and talk about what makes that object so interesting to astronomers. So let’s now turn on the random number generator.

The coordinates for this episode are 11:40:16.9 right ascension and +17:43:41 declination. This points to the galaxy NGC 3801, which is located at a distance of roughly 176 million light years (54 Mpc) from Earth in the constellation Leo. 

The audio was recorded and edited by Dr. George Bendo, an ALMA contact scientist at the University of Manchester. The sound effects are from The Freesound Project at www.freesound.org. Thanks for listening!

From January 7, 2008.

Now that you’ve got your career in astronomy, obviously the next goal is to win a Nobel prize. We’re here at the American Astronomical Society meeting in Austin, which is just one tiny step that a person has to take before you get that Nobel prize. Before you get that call in the middle of the night from Sweden, you’re going to need to come with an idea, do some experiments, write a paper, get published and a bunch of other stuff. This week, we’ll tell you all about it.

Today's 2 topics:

- It was murky cloudy night on Mt. Lemmon where I was trying to find Earth approaching objects with the Catalina Sky Survey 60 inch telescope. At about 1AM another hole in the clouds opened and I could see stars on the all sky video camera. On this fourth attempt, one set of images showed a bright rapidly moving object. Followup observations by my teammate Greg Leonard using the Catalina Sky Survey 40 inch telescope next door and two different observers in Japan provided the data which allowed the Minor Planet Center to calculate an orbit, estimate a size, predict its path in the sky, and give it the name 2016 VA. Twenty hours after I discovered it, Dr. Gianluca Masi using the Virtual Telescope Project facility 56 miles south of Rome, Italy, repeatedly imaged 2016 VA as it made an 11 minute passage through the Earth's shadow. He used these images to make a remarkable video of this tiny asteroid as it passed through the Earth's umbra. It was the fastest asteroid that he had ever tracked. Fortunately a bit after this video, 2016 VA missed the Earth by about 59,000 miles while traveling at a speed of 13 miles per second relative to us. In 2024 it will once again come near to both the Earth and our Moon.

- Egg rock's chemical composition and visual appearance is so different from other native Mars rocks that scientists have concluded that it is a meteorite which came from the molten core of an ancient asteroid.

Episode 1a: The Relativity Vault

We’re all going to die. But let’s say you’re going to die from some incurable disease – or even just from

ageing – and you’ve got some time to plan ahead. One option is to assume that future science could

save you. A common strategy to access this option is to get yourself frozen – or even just get your head

frozen –until medical science can find a cure for whatever ails you.

Episode 1b: The welcome note

One solution to Fermi’s paradox – about why there’s a universe of potentially habitable worlds out

there, but no-one’s talking - is that we are the first, or at least one of the first technology-exploiting

species. After all, it’s unlikely much could have happened when the early Universe full of hydrogen,

helium and a few trace elements – you need stellar nucleosynthesis to build more complex elements

and supernovae to spread those elements out.

From Aug 25, 2023.

The next big milestone in our study of exoplanets is  a telescope that can see beyond the limits of our eyes, beyond the boundaries of our solar system, beyond the frontiers of our knowledge. A telescope that can reveal the secrets of the stars and the mysteries of the planets. A telescope that can take us closer to finding another home in the cosmos. That telescope is the Nancy Grace Roman Space Telescope, a NASA observatory that is scheduled to launch in May 2027 and explore a wide range of astronomical phenomena, including exoplanets.

Let's talk about that giant telescope that's changing everything. We have been waiting our entire careers to make this episode on the James Webb Space Telescope, AKA the JWST. This historic Observatory was launched just a couple of years ago and it's already overturning our understanding of the early Universe star formation and exoplanets!

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

From July 28 & August 4, 2023.

Today's 2 topics:

- In 2023 the James Webb Space Telescope spotted a geyser of water vapor extending more than 80% of the Earth’s diameter erupting from Saturn’s moon Enceladus. If life does exist in the salty ocean of Enceladus shielded from the rest of the Universe by a thick layer of ice and rock its nature remains a mystery.

- My Catalina Sky Survey teammate David Rankin was asteroid hunting in the constellation of Cancer with our Schmidt telescope on Mt. Bigelow, Arizona when he discovered a potentially hazardous asteroid, 2023 KM5. Rest assured there is no way, on its current path, that 2023 KM5 will impact the Earth in the foreseeable future, however, asteroid hunters will continue to track it to make sure its orbit does not change to make it a threat.

The Observer’s Calendar for October 2024 and Comet C/2023 A3 Tsuchinshan-Atlas on Episode 450 of the Actual Astronomy podcast. I’m Chris and joining me is Shane. We are amateur astronomers who love looking up at the night sky and this podcast is for everyone who enjoys going out under the stars.

- Oct 1 - Zodiacal light is visible again this month. Actually, Alister and I observed it back on Sept. 8th, so it does become visible even in late summer. Look towards East or just north of east and it’s a pyramid shaped pillar of light pointing somewhat towards M45, the Pleiades star cluster.

- Oct 2 - New Moon! Also an annular solar eclipse on this day…but only for extreme southern tip of South America and center of Pacific…let us know if you see this!

- Oct 5 - Venus as close as 3° to the Moon in Evening Sky

- Oct 10 - First Quarter Moon

- Oct 14th - Saturn Pairs as close as 0.1° of Moon and Occultation for parts of Africa…so if anyone is there…hint hint…we have a friend visiting Africa for astronomy who will join us in coming weeks.

- Oct 15th - Neptune just over ½° from the Moon and occultation for other regions including Africa.

- Oct 17 - Full Moon - Largest in 2024 - I don’t know if it’s super or not…large tides this week too.

- Oct 19 - Moon Near Pleiades this evening

 -Oct 20/21 - Orionid meteors peak but Moon interferes but it pairs with Jupiter for a nice sight, as close as 0.6°

- Oct 24th - Last Quarter Moon

Comet C/2023 A3 Tsuchinshan-Atlas - 

Best night here will be Oct 15th when it passes Messier 5, a Globular Star Cluster in Serpens. Comet is forecast to be at Mag. 3 that night!

Last week, we talked about the Parker Solar Probe. As always, we like to talk about the person who inspired the mission. What makes this amazing and different is that Eugene Parker was there to watch the launch of the mission that shares his name. Why is he so influential on solar astronomy?

Today's 2 topics:

- One meter diameter 2022 WJ1 holds the record as the smallest asteroid ever detected! It even hit the ground as it entered Earth’s atmosphere.

- Very small fast moving asteroids pass through our solar system.About once a month an object like 2023 KU4 enters our atmosphere, releases the energy of approximately 2.4 tons of TNT, explodes at an altitude of about 280,000 feet, creates a spectacular light show, produces a sonic boom that is barely audible, and rains pieces of itself on the ground for meteorite hunters to discover. Check out the fireball log on the American Meteor Society website for examples.

The 5th of December 2022 sees the commencement of construction of the long-awaited Square Kilometre Array (SKA)!

SKAO: https://www.skao.int/

The SKA Observatory (SKAO) is a next-generation radio astronomy facility that will revolutionise our understanding of the Universe and the laws of fundamental physics. Formally known as the SKA Observatory, the SKAO is an intergovernmental organisation bringing together nations from around the world. The observatory consists of the SKAO Global Headquarters in the UK, the SKAO’s two telescopes at radio-quiet sites in South Africa and Australia, and associated facilities to support the operations of the telescopes.

The SKA telescopes:

Composed of respectively hundreds of dishes and thousands of antennas, the SKAO’s telescopes will be the two most advanced radio telescopes on Earth. Together with other state-of-the-art research facilities, the SKAO’s telescopes will explore the unknown frontiers of science and deepen our understanding of key processes, including the formation and evolution of galaxies, fundamental physics in extreme environments and the origins of life.

Hosted by Pamela Gay with guest Latif Nasser.

https://www.iau.org/news/pressreleases/detail/iau2406/

The International Astronomical Union and WNYC’s award-winning science podcast, Radiolab, invite people worldwide to take the unique opportunity to suggest a name for one of Earth's quasi-moons, 2004 GU9. Submissions are open until 30 September and the winning name will receive official recognition by the IAU.

https://radiolab.org/moon-official-rules/

For millennia, people across the globe have built deep connections to objects in the night sky, assigning them names and stories imbued with their cultural heritage and understanding of the world. Naming campaigns highlight these connections and provide the global public with a chance to have their creativity embedded in the cosmos.

Earlier this year, Latif Nasser, co-host of the science podcast Radiolab ( https://radiolab.org ), petitioned the International Astronomical Union (IAU) to name a quasi-moon of Venus after noticing a typo on a map of the Solar System. The saga was documented on a Radiolab episode and tweet thread from Nasser that went viral, opening the door for listeners to learn more about this fascinating class of objects. The episode established a connection between the IAU and Radiolab, which is produced by WNYC Studios [1]. The organisations have now teamed up to invite a global audience to engage with this field of astronomy through a new naming contest for one of Earth’s quasi-moons.

Quasi-moons of a planet are asteroids that orbit the Sun and follow a path similar to that of the planet. Due to the relative motion of the two objects, it appears as though the asteroid is orbiting the planet from the perspective of an observer on the planet’s surface. If a quasi-moon is near the Earth, it might seem as if we have a new moon, even though it is hardly affected by the Earth's gravitational pull.

By taking part in “Name a Quasi-Moon!”, people worldwide will have the chance to leave their mark on our sky with official recognition from the world’s authority responsible for assigning names to objects in our Solar System and beyond. By involving the IAU’s wide international network, the collaboration will reach new audiences, ensuring our sky will be more representative of the world’s diverse ideas, cultures, perspectives, and ways of knowing.

From August 24, 2023.

New Webb Telescope Observations Suggest Not…

A team of astronomers used the James Webb Space Telescope to study the exoplanet TRAPPIST-1 c, which is one of seven rocky planets orbiting an ultracool red dwarf star 40 light-years from Earth. The team found that the planet's atmosphere, if it exists at all, is extremely thin.

TRAPPIST-1 c is about the same size as Venus and receives a similar amount of radiation from its host star as Venus gets from the Sun. This led scientists to believe that the planet might have a thick carbon dioxide atmosphere like Venus. However, the Webb observations suggest that this is not the case.

Let's look over the long life of the Parker Solar Probe as it explores the Sun and nearby worlds.

The Sun! It’s that ongoing thermonuclear explosion that’s happening right over there! And although the Sun is necessary for life on Earth, we still have questions! So NASA has sent the Parker Solar Probe to visit the Sun up close, to get us some answers.

From June 30, 2023.

Today's 2 topics:

- To the amazement of NASA scientists, when the NASA OSIRIS-Rex touched down on the surface of Bennu to obtain a sample, the sample collecting arm continued to sink into Bennu until rocket thrusters reversed its downward motion and allowing it to escape.

- My Catalina Sky Survey teammate Jacqueline Fazekas was asteroid hunting, in the evening twilight, with our 60 inch telescope on Mt. Lemmon, Arizona when she discovered a very large object in an unusual orbit. Rest assured that astronomers will continue to track Jacqueline's discovery, 2022 KL8, to make sure that its orbit does not change to make it a threat as it passes near Jupiter, Earth, and Venus.

This questions assumes any interstellar travel from Earth will be undertaken by robots rather than us, This is a reasonable proposition given that going to the nearest star would take at least forty years assuming you can achieve speeds in the order of ten percent of the speed of light, which is a pretty big assumption.

Dear Cheap Astronomy – Do we really need to send humans into space?

Well yes, we really do. Cheap Astronomy is a big advocate for getting robots, our manufactured progeny out there, but the technology isn’t yet good enough for robots to replace the role and function that people will play. They robots will be able to do all those things one day and on that day us humans can just stay home and let them get on with it, but before then there’s a gap that needs to be filled – and there is some growing urgency to get on with it soon.

In this Astronomy 101 video we take a look at Comets!

From the medieval portends of doom to the space age where we know that they've been devastating the solar system for billions of years. But what are they? Where do they come from? And did they bring life to Earth?

The internet. It gives us an instant connection to the sum of human knowledge, but it also lets misinformation travel at the speed of light. Everyday I get comments about how people will believe we’ve been to space after I show them evidence of actual spacecraft taken in space and not CGI mock-ups.

Challenge accepted. Here come a whole bunch of photos of spacecraft taken in space. Actually, I don’t really care if you believe it or not. I was just so excited about some of the fantastic pictures of spacecraft - taken by spacecraft - that I decided to dedicate a whole episode to it.

Why are private space companies pushing tourism? Is there a future for tourism in space? Is this an overall good thing for space exploration?

Paul Sutter’s personal hot take: “Meh. I find space tourism kinda interesting... Space tourism isn’t moving the needle much in any direction.”

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- More than 400 years ago Galileo Galilei expanded human vision using a telescope to view the cosmos. Since then humans have extended their senses to view the Universe in x-rays, ultraviolet, infrared, radio, and other portions of the electromagnetic spectrum not accessible to our senses. In a pioneering effort, Ekaterina Smirnova has employed the spectroscopy, magnetometry, and molecular data collected by the Rosetta spacecraft to create watercolor paintings, sculptures, a musical collaboration, and an augmented reality project to create new art forms.

- My Catalina Sky Survey teammate Rose Matheny had no way of knowing that the fast moving point of light that she had just discovered would create such a stir. Rose sent in her discovery and followup observations to the Minor Planet Center where astronomers calculated that her discovery would make a very close approach to Earth about two days later and gave it the name 2016 RB1. More than two dozen observatories around the world tracked 2016 RB1 as it came towards us.

Kilonova form when two neutron stars collide. They were first discovered by their gravitational wave emissions. In this podcast, NOIRLab’s Dr. André-Nicolas Chene described the discovery of a system that will become a kilonova in the future.

Bios: 

Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona..

André-Nicolas Chene is an associate astronomer at NOIRLab. He completed his PhD at the Université de Montréal in 2007 and learned everything about the fundamentals of astronomical observations at the Observatoire du Mont Mégantic. He was research fellow at the NRC Herzberg Astronomy and Astrophysics Research Centre and postdoc jointly at the Universidad de Concepción and the Universidad de Valparaíso before joining the Gemini Observatory (now a program of NOIRLab) in 2013. For almost 10 years, André-Nicolas took part in every phase of a Gemini observing program life cycle and has played a central role in Gemini's user support effort. André-Nicolas’s research interests are massive stars, hot winds, star clusters, and stellar evolution.

Things that orbit the Sun and clear their orbits.

Dear Cheap Astronomy – What happens when worlds collide?

The outcome of a collision between two planets depends on the speed of the collision, the angle

of the collision and the relative masses of the two bodies and their composition – think rocky

planets versus gas giants for example. A small planet approaching a large planet slowly might

get tidally stretched and break up into pieces, but a fast moving one might impact before there’s

been time for gravitational stretching to break it up.

Dear Cheap Astronomy – Why is Mars’ sky red?

A good place to start is to think about the colours we are familiar with in Earth’s sky. In the

middle of the day, the overhead Sun is a bright white disk you can’t look at directly and the rest

of the sky is blue.

This is because most of the visible light from the Sun passes straight through the atmosphere,

which is transparent to those wavelengths, except at the very short end – so rather than passing

straight through, photons in the blue and violet parts of the visible spectrum are scattered –

meaning they are deflected off their straight line path and bounce around a lot, although most

eventually reach the ground.

Astronomers estimate that there are more free roaming planets in our galaxy than there are planets in orbit around stars. In fact, rogue exoplanets - planets with no star whatsoever - far outnumber all other planets in our galaxy, by 20 times. Trillions of worlds wandering alone.

Trillions of neutrinos are produced in our Sun through its nuclear reactions. These particles stream out at nearly the speed of light, and pass right through any matter they encounter. In fact, there are billions of them passing through your body right now. Learn how this elusive particle was first theorized and finally discovered.

I don’t want to alarm the listeners but there is a flurry of particles from the Sun passing through each and every one of you right now. A lot of particles. In fact, there are 50 billion solar neutrinos passing through every one of us every second. Don’t worry, you can’t feel them; they barely interact with matter, but that’s what makes them interesting.

What is gracing the September 2024 skies?  A juuuuust barely partial lunar eclipse, the best viewing for Saturn, 5 lunar close encounters, and the transition to fall.

Hi everybody, I’m Rob Webb, your Last Minute Astronomer, bringing astronomy to normies and nerds, with little time to spare.

We’ll start by talking about September’s big events, then highlight the naked eye planets, and finish up with the lunar phases, so you can plan ahead better than me.  

7th – 8th – Opposition of Saturn – Saturn, Earth, and the Sun are essentially lined up, causing Saturn to rise at sunset, and set at sunrise, with best viewing around midnight.

17th - Just Barely Partial Lunar Eclipse - The Moon passes into the shadow that Earth is casting into the solar system, but only a little.  Times here are Eastern Daylight, so adjust for your location, assuming you are in the Americas, Africa, or Europe.  The penumbral stage will be almost not noticeable, however the hour of partiality will be.  At 10:12pm the Moon will start to graze the dark inner portion of the Earth’s shadow called the umbra.  About half an hour later it’ll be at maximum eclipse, with 8% of it covered up.  Another half hour later, the dark shadow will no longer be noticeable, and the moon will be in the penumbra until 12:47am.

8:41pm - Penumbral Eclipse Starts

10:12pm - Partiality Starts

10:44pm - Maximum Eclipse (8%)

11:15pm - Partiality Ends

12:47pm - Penumbral Eclipse Ends

The September 2024 Observer’s Calendar on Episode 446  of the Actual Astronomy podcast. I’m Chris and joining me is Shane. We are amateur astronomers who love looking up at the night sky and this podcast is for everyone who enjoys going out under the stars.

* Sept 1 - Zodiacal light becomes visible this month

   (Mercury is also paired with the Moon in morning, but might be tough)

* Sept 3 - New Moon

* Sept 5 - Mercury at Greatest Elongation 18-degrees from Sun in Morning Sky

* Sept  8 - Saturn at Opposition

   * Mars 0.9 degrees from OC M35 after midnight

* Sept  9 - Mercury 0.5 degrees North of Regulus in morning sky

* Sept 10 - Antares Occultation by the Moon for places like Australia and Indonesia

* Sept 11 - First Quarter Moon

* Sept 17 - Saturn Occulted by the Moon - Visible barely here just about 5:30am so you want to ideally be west of the Saskatchewan/Alberta Border…straight through NA.

* Sept 18 - Partial Lunar Eclipse - Best visible from Brazil and region but most of Eastern NA and Western Europe and Africa

   * It is a small partial..just a little chunk goes through the Umbra

   * BUT YOU SHOULD GO LOOK

   * BECAUSE

   * At 1:15 am Saskatchewan Time…so that’s 3:15 am EDT the Moon Occults Neptune for most of us in NA except southeastern reaches of USA.

* Sept 21 - Neptune at Opposition

* Sept 22 - Equinox

      (Moon 0.2-degrees from Pleiades)

* Sept 25 - last quarter Moon

From Dec 9, 2022. At AstroCamp.

Astronomy 101 - Everything you need to know about asteroids!

- What are they?

- What are they made of?

- Where are they??

Dr. Jen tells us how we understand so much about these small(ish) objects far away in the Asteroid Belt. Is the asteroid Belt really like the sci-fi depictions and are there other places in the solar system where these fragments of the early solar system roam? And no talk on asteroids would be complete without considering the threat to Earth (and all life on Earth) from them...

From July 7, 2008.

And now we reach the third part of our trilogy on the human exploration and colonization of Mars. Humans will inevitably tire of living underground, and will want to stretch their legs, and fill their lungs with fresh air. One day, we’ll contemplate the possibility of reshaping Mars to suit human life. Is it even possible? What technologies would be used, and what’s the best we can hope for?

From Aug 5, 2016.

The Earth’s tilt is nothing compared to Uranus, which has been flipped right over on its side. What could have caused such a devastating impact to the planet to make it this way?

It’s impossible to do an episode about Uranus without opening up the back door to a spit storm of potty humour. I get it, there’s something just hilarious about talking about your, mine and everyone’s anus. And even if you use the more sanitized and sterile term urine-us, it’s still pretty dirty, in an unwashed New York stairwell kind of way. You’re in us? No.

Building the future!

Dear Cheap Astronomy – How will we build a lunar base?

The main issue with building on Earth is gravity – that is, if you’d don’t build them properly they

will fall over. With the Moon having one sixth of earth’s gravity, stopping things from falling over

is still important but it’s a much easier thing to accomplish. The main challenge for building

structures for people to live in on the Moon is that those structures will need to retain internal

pressure against a vacuum.

Dear Cheap Astronomy – Will travel to Mars ever become routine?

There is a view that whenever we do send astronauts to Mars, they won’t fly there in one

spacecraft. Their launch vehicle from Earth might dock with an orbiting deep space vehicle,

which is built for deep space travel in a vacuum and would never have survived a launch

through Earth’s atmosphere.

Damien Phillips, John Wildridge and Dustin Ruoff produce.

Today we bring you two of the plenary sessions from the British Planetary Science Conference, 2024, hosted by Space Park Leicester and the National Space Centre on June 18-21, 2024.

- Dr. Aprajita Verma of the UK ELT Programme.

- Dr. Steven G. Banham Research Fellow in planetary surface processes at the ICL.

The Space Park newsletter reports: 

Dr. Jenifer Millard, Managing Editor at Fifth Star Labs, added: “I attended BPSC2024 not as a planetary scientist, but as an astronomer and science communicator, hoping to be inspired and learn beyond my field of expertise. … I’m delighted to say I was not disappointed by the event Space Park Leicester enabled. It was a fantastic few days of learning in a wonderful, encouraging and most importantly safe environment.”

The conference was supported by the UK Space Agency, the Science and Technology Facilities Council (STFC), Europlanet Society and the Royal Astronomical Society.

From Aug 22, 2023.

One of the big questions we are trying to answer in exoplanet astronomy is: Just how common are habitable planets?  We already know that exoplanets themselves are extremely common: Astronomers tell us there are on average 1.6 planets for every star in our galaxy, so there are more planets than stars out there.

That by itself is pretty amazing, but what we really want to know is, where’s the life?  How common are planets that could potentially support life?

After astronauts make the first tentative steps onto the surface of Mars, a big goal will be colonization of the Red Planet. The first trailblazers who try to live on Mars will have their work cut out for them, being in an environment totally hostile to life. What challenges will they face, and how might they overcome them?

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- Using a small telescope or a set of binoculars you can see Europa for yourself as a small moving point of light circling the giant planet Jupiter. More than 400 years after Galileo Galilei discovered this seemingly small dead world the Hubble Space Telescope spotted geysers erupting from its south polar regions. Recently, over a 15 month period, the Hubble was able to observe 10 transits of Europa across the face of Jupiter. On three such occasions plumes were seen to be erupting from this small moon.

- A pair of comets visiting our neighborhood are discovered in a matter of 4 days. 

One of the perks of being an asteroid hunter is having a comet named for you. To do this you must be the first to discover it as a moving point of light in the night sky and at the same time recognize that it is a comet by observing the coma and tail which are names for the clouds of gas and dust that surrounds it. After being on the lookout for a comet for sometime, my Catalina Sky Survey teammate Rose Matheny discovered two of them within a 4 day period of time. Both of them C/2016 T1 (Matheny) and C/2016 T2 (Matheny) are likely to be first time visitors to the inner solar system. These two comets have quite different paths which are both inclined at large angles to the paths of the planets about the Sun. In addition, both of them are traveling at very close to the escape velocity from our solar system and have uncertain orbital periods around the Sun which are likely to be thousands of times the age of the Universe.

- Dear Cheap Astronomy – What’s the best way to redirect an asteroid’s path for mining purposes?

Let’s start by saying CA's plan to somewhat indiscriminately crash $#!+ on the Moon is not actually that indiscriminate. It’s not realistic to think you can shift an object several kilometres in diameter out of the asteroid belt and onto a precise trajectory that will have it collide with the Moon – at least not without some implausible engineering and fuel supply.

- Dear Cheap Astronomy – Part 2 of What’s the best way to redirect an asteroid’s path for mining purposes?

So, to recap. It’s unlikely we are going to achieve zero population growth anytime soon, so we’ll eventually need more resources. While eventually might be a long time coming – we’ll need to put the skills and infrastructure in place so that we’re ready when ‘eventually’ does come.

Kelt-9b is a gas giant planet that orbits a star 670 light-years from Earth. It is so close to its star that its dayside temperature is 7,800 degrees Fahrenheit (4,300 degrees Celsius), hotter than some stars. This heat is so intense that it rips apart the molecules in the planet's atmosphere, including hydrogen gas.

From November 20, 2006.

The discovery of dark energy was one of the biggest surprises in astronomy. Instead of a nice, predictable expanding Universe, acted on only by gravity, astronomers turned up a mysterious repulsive force accelerating the expansion of the Universe. Fraser and Pamela explain the evidence for a dark energy, and a few possible theories for what could be providing this repulsive force.

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- On a cold windy night, with clouds frustrating his search, my Catalina Sky Survey teammate Alex Gibbs discovered 8 new celestial visitors while observing with our 60 inch telescope on Mt. Lemmon, Arizona.

- On a recent training night with Teddy Pruyne at the controls of our 60 inch telescope on Mt. Lemmon, Arizona, this duo discovered six new Earth Approaching Objects, an inner main belt asteroid, and rediscovered an inner main belt asteroid which had been lost.

At present there are over 5,600 confirmed exoplanets in just over 4,000 star systems. Within this population, about 300–500 exoplanets fall into the curious class known as hot Jupiters — large, Jupiter-like exoplanets that orbit very close to their star. How hot Jupiters form is an area of active research. Recently the WIYN 3.5-meter Telescope at Kitt Peak discovered an exoplanet with a strange orbit that gives clues to the formation of these unusual objects. In this podcast, Dr. Arvind Gupta discusses this rare and unusual planet.

Dr. Arvind Gupta is a postdoctoral fellow at NOIRLab in Tucson, Arizona. His primary research focus is on the design, execution, and analysis of exoplanet searches with extreme precision radial velocity spectrographs in pursuit of Earth analog discovery. H is also actively engaged in observational work to discover and characterize long-period giant exoplanets and studies of hot and warm Jupiter formation and demographics. Other general interests include stellar variability, information theory, and habitability, as well as astronomy accessibility and pedagogy.

From May 18, 2021.

Two new studies are attempting to solve a couple of big puzzles in astrophysics: Is the Hubble constant actually constant? And why do galaxies have flat rotation curves? Plus, a young star’s circumstellar disk, the search for stellar-mass black holes, magnesium in the deep waters of Neptune and Uranus, and an interview with PSI scientist David Horvath regarding possibly active volcanism on Mars.
