Gravity Waves ... not gravitational waves ... move atmospheres and make pretty clouds. Have you ever looked up into the sky and seen bizarre cloud formations that look like waves on the ocean? These are gravity waves. Not to be confused with gravitational waves, and they’re caused by a balance of buoyancy and gravity. And of course these have been seen across the solar system.

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 August 2024.

Today's 2 topics:

- Richard Kowalski discovered  2016 WM48, a Centaur. Centaurs are named after the mythical beasts which were half human and half horse perhaps because they have characteristics of both asteroids and comets. 2016 WM48, is about a mile in diameter. We don't know if it has rings, tiny moons, or a gas cloud surrounding it as some other Centaurs do. 2016 WM48 must have had a catastrophic collision in the past few million years which put it on a very elliptical path which is tipped at 60 degrees or so to the solar system's plane.

- The asteroid Psyche may be one of the most expensive pieces of real estate in the solar system. It is a small world about 116 miles in diameter and is composed of almost pure nickel-iron metal. It is located in the asteroid belt between Mars and Jupiter. Scientists find evidence that Psyche may be the exposed core of a planet which was destroyed by collisions as it was trying to form long ago.

February 2025 is a phenomenal continuation of January’s planetary-ness! You’ll get chances to see all the planets before going to bed and a conjunction of Mercury & Saturn.

Hi everybody, I’m Rob, your Last Minute Astronomer, bringing astronomy to normies and nerds, with little time to spare. We’ll start by talking about this month’s big events, then highlight the naked eye planets, and finish up with the lunar phases, so you can plan ahead better than me.

LUNAR CLOSE ENCOUNTERS 

The Moon will be traveling across the sky as normal, passing by some planets at particular times. 

1st - 2nd - Saturn has dipped below Venus in the sunset sky by about 12°, and a very thin crescent Moon joins in on the 1st, within 3° of Venus. Then, on Feb 2nd, the Moon, Venus, and Saturn make a string of objects just after sunset in the SW.

6th - Find the Waxing Gibbous Moon just about 5° above bright Jupiter moving West throughout the night, setting just before 3:30am.

9th - The Moon will start out the night just 2˚ from Mars, moving further away throughout the night, setting around 6am.

From January 2024.

Today's 2 topics:

- A research project whoes goal is to explore if it would be possible, on short notice, to pulverize a small asteroid so that it would not enter the Earth’s atmosphere as a single object perhaps saving humanity from an very expensive sonic boom.

- My Catalina Sky Survey teammate David Rankin was being filmed and interviewed by the NASA 360 crew at our 60 inch telescope on Mt. Lemmon, Arizona when he discovered a scary space rock moving through the constellation of Aquarius at 13 mi/s.Rest assured that asteroid hunters will carefully keep track of 2023 VS3 to make sure that its orbit does not change to make it a threat in the distant future as it passes near to Earth, Mars, and other asteroids.

This is a re-run of episode 29 of The Cosmic Savannah in anticipation of an upcoming interview with Prof Matthew Bailes so all our listeners can get up to speed about everything to do with Neutron Stars!

We are firstly joined by Prof. Matthew Bailes from the Centre for Astrophysics and Super computing at Australia’s Swinburne University of Technology. Matthew is a world expert on pulsars and the Director of the “OzGrav” ARC Centre of Excellence for Gravitational Wave Discovery.

Matthew chats with is us about pulsars, gravitational waves and some of the incredible science we can expect from projects such as Meertime. MeerTime will use the MeerKAT telescope to explore fundamental physics and astrophysics using radio pulsar timing.

We’re then joined by Katia Moskvitch, who was the 2019 British Science Journalist of the Year and the 2019 European Science Journalist of the Year! Katia tells us about a her new book “Neutron stars: The Quest to Understand the Zombies of the Cosmos.” This popular science book is written for a general audience and describes the fascinating and bizarre existence of neutron stars and pulsars.

Today’s guest is Dr. Seb Falk is the recipient of HAD’s 2025 Osterbrock Prize for his book “The Light Ages: the Surprising Story of Medieval Science”. His exceptionally well-written book takes the reader on a learning journey with the 14th century Benedictine monk John Westwyk who, at the end of his career in 1392, wrote an instructional manuscript in Middle English for an equatorie to compute a planet’s location. Originally discovered in 1951 and attributed to Chaucer, 30 years later the manuscript’s author was identified as Westwyk.  Based on years of meticulous scholarly research, Falk teaches the reader detailed, and progressively complicated, 14th century science in this thoroughly pleasurable story about Westwyk’s life.  

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.  

Podcaster: 

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.

Inclusive astronomy outreach is possible with simple tools: Tactile sheets, 3D models, and balloons with star stickers are powerful resources for teaching astronomy to the blind, making the Universe accessible to all.

- Cesare Pagano and Andra Stoica discuss their roles in the Inclusive Outreach sub-working group of the International Astronomical Union, focusing on making astronomy accessible to people with disabilities.

- Andra Stoica explains how tools such as tactile sheets and 3D models allow visually impaired individuals to experience and understand astronomical concepts.

Why stars can’t be trusted!

If you’re an astronomer you depend on accurate observations of stars, but there’s a problem. Stars are sneaky! Changing in size, brightness, color, they hide their chemistry, their age and even their companions from all but the cleverest observers. Stars explode precisely when they intend to. Betelgeuse took a brightness plunge, T CrB refused to go nova, and other failures to be predictable irk observers for good reasons. Let's talk about it.

Join us today as we talk about newly released research that suggests the waters on ancient Mars were subglacial and not free-flowing. Also, a black hole goes dormant and star formation goes wild. Meanwhile, computer models show that unequal neutron stars colliding may cause a big “bang” that can be detected on Earth.

Hosted by Tony Darnell.

Human beings have discovered over five thousand five hundred exoplanets.  Over 80 percent of them have orbits shorter than 50 days which would place them at over twice as close to their star as Mercury is to the Sun.  Some are even closer.  Recent observations from TESS however have found one with an orbit of 82 days and another measured in hundreds of days.

From little Ingenuity to the future Firefly and all our Earth Science fliers, let's look at the buzzy scientists. NASA’s Mars Ingenuity helicopter showed us how wonderful a flying science platform can be on another world. Soon there’ll be a helicopter flying on Titan, but there are many other flying robots that’ll be helping us with all our science needs.

Supermassive black holes exist at the center of most galaxies, and modern telescopes continue to observe them at surprisingly early times in the Universe’s evolution. It’s difficult to understand how these black holes were able to grow so big so rapidly. But with the discovery of a low-mass supermassive black hole feasting on material at an extreme rate, seen just 1.5 billion years after the Big Bang, astronomers now have valuable new insights into the mechanisms of rapidly growing black holes in the early Universe.

In this podcast, Hyewon Suh and Julia Scharwächter discuss the discovery of LID-568, a black hole that is feeding at 40 times the theoretical limit.

Bios:

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

Hyewon Suh’s research mainly focuses on the multi-wavelength studies of Active Galactic Nuclei and their host galaxies to understand the growth of black holes in the context of galaxy evolution. While the deep, large-area extragalactic surveys have greatly enriched our knowledge of the early universe, there are several missing pieces in the understanding of the formation and the growth of supermassive black holes. She is interested in the most energetic and obscured phase of accreting black holes to explore the formation of the first accreting black holes, and to provide the crucial observational constraints on a hidden phase in the early universe.

Julia Scharwächter’s main research area is the (co-)evolution of galaxies and their supermassive black holes. She is interested in studying the role of AGN feedback and the nature of black hole mass-host galaxy scaling relations. Her observational projects mostly aim at spatially resolved studies of galaxy nuclei in the nearby Universe. She uses 3D spectroscopy in the optical, near-infrared, and at millimeter wavelengths to probe the stellar and gas component in galaxies, with a special focus on gas-kinematic black hole mass measurements and gas excitation/kinematics around AGN. She is also interested in galaxy dynamics and galaxy merger simulations using N-body/SPH codes.

From April 27, 2021.

The biggest mass extinction event on Earth occurred at the end of the Permian period, resulting in the extinction of 95% of marine life and 80% of terrestrial life. Now, scientists have found that the terrestrial portion of the event lasted nearly ten times as long as the ocean version. Plus, a spaghettified star, the search for Moon Trees, all about Mars, and new works on dark matter and dark energy.

Today's 2 topics:

- New observations linked with discovery observations 10 years earlier provide a significant improvement in the precision of our knowledge of 2013 TG6’s orbital elements and thus its position on the sky well into the future.It is important for asteroid hunters to keep track of small asteroids like this one to make sure sure that their path doesn’t change to make them a threat as they pass other objects in space.

- The Catalina Sky Survey searches the sky as rapidly as possible in search of Earth approaching objects that could pose a threat to our home planet. The Vera Rubin Observatory will obtain 200,000 images per year to discover things that move or change brightness down to a very faint magnitude.

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 January’s big events, then highlight the naked eye planets, and finish up with the lunar phases, so you can plan ahead better than me. 

January 2025 is a PLANETARY month! Mars gets big, Mars gets occulted, Mars gets outshined by Venus, Saturn, and Jupiter, then Venus and Saturn pass right by each other, and a brief but intense meteor shower shows up. 

13th - Occultation of Mars - MORE than a close encounter, Mars will be right next to the Moon all night, except for about an hour when the Moon occults Mars.  Around Philadelphia, the occultation starts at 9:17pm, when the Moon passes right in front of Mars.  This lasts until about 10:32pm, when Mars pops back out on the other side of the Moon.

Dear Cheap Astronomy – Why do further way galaxies moving faster mean the Universe is expanding?

It is all a lot to take in – not only is farther away stuff moving faster, also the Universe is expanding faster now than it was in the past and there’s standard candles and red-shift and much room for confusion.

Dear Cheap Astronomy – Is there such a thing as a dead planet?

To start with it’s probably unreasonably biocentric to define spherical objects that orbit the Sun and have cleared their orbits, as either alive or dead. We can redefine the question in terms of being geologically-active or not, but there it gets difficult to draw a line between what’s active and what isn’t.

Astronomers think that studying the effects of spaceweather and radiation in space will shed more light on exoplanetary atmospheres. You see, spaceweather is what we call the variations in the space environment. 

Here in our solar system we experience spaceweather as solar wind, solar flares, solar storms, coronal mass ejections from the Sun and even cosmic rays from the rest of the Universe.

Did you see the aurora borealis this year?

That’s spaceweather!

We take the Moon for granted, but its effect on the Earth is very important; possibly even critical for the formation of life. But where did it come from? Did the Earth and Moon form together? Or did the Earth capture a wayward Moon? Or was there a more catastrophic cause to this lunar mystery?

Today's 2 topics:

- NASA classifies 2023 SZ1 as a Potentially Hazardous Asteroid since it is larger than 140m in diameter and on its current path can come to about 6 times the Moon’s distance from us.Fortunately on its current path 2023 SZ1 will not come any closer than 42 times the Moon’s distance from us until after 2171.

- Marcel Drechsler, Xavier Strottner, and Yann Sainty’s image of our neighboring galaxy, M31, in Andromeda won the 10,000 British pound Astronomer Photographer of the year award for 2023. Amazingly their image revealed a huge, previously unknown arc of hot doubly ionized Oxygen gas.

In this episode, Tshiamiso and Dan have a discussion with Alexander Andersson from Oxford University about Zooniverse, citizen science projects and how citizens can contribute to the work that astronomers do.

During the episode Alex discusses how important and useful the work done by participants in the Bursts from Space project is for helping scientists train AI in the search for radio transients – or as Alex puts it: “Things that go bump in the night”.

Join us for another exciting episode and learn how you can contribute to the fascinating research going on in Astronomy today!

Alexander Andersson is a PhD student at Oxford University in the United Kingdom. His work focuses on Machine Learning applications to data collected by the MeerKAT telescope. Alex is also involved with the Zooniverse citizen science project. Specifically, Alex is working on the Bursts from Space project using the Zooniverse platform in order to train AI to identify radio transients.

From July 17, 2021.

Over tens of millions of years, the surface of Europa has been churned by impacts down to an average depth of 30 centimeters. This churning means that the search for chemical biosignatures must look below that zone. Plus, methane and icequakes at Enceladus, predicting underwater eruptions, Virgin Galactic's flight, and a Chinese spacewalk.

Hosted by Loretta Cannon for the AAS-HAD.

Historical Astronomy Division of AAS

https://had.aas.org/

Today’s guest: Dr. Linda Spilker (JPL Fellow and Senior Research Scientist) discusses the Cassini mission to Saturn (1997-2017) that she worked with for 30 years, the last 10 as Project Scientist.

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.

From September 6, 2023.

Hosted by Tony Darnell.

Astronomers have recently concluded an observation study of the closest exoplanet to Earth, Proxima Centauri b and found that the planet does not transit its star.  These observations settle a question that astronomers have been asking since the exoplanet's discovery in 2016 using the radial velocity method.

What can we hope (or dread) to see in 2025?

Last week we talked about the 2024 strangeness. Now we’re gonna talk about the upcoming space stories for 2025 that we’re looking forward to. It’s a nice mix of new rockets, new missions and new fly-bys.

- Given the effects of climate change today who can predict what planet Earth will be like when C/2023 P1(Nishimura) comes back near our home planet in approximately 2455 AD.

- Hycean Worlds, with masses between Earth and Neptune which have thin hydrogen rich atmospheres above a liquid water ocean may be very common in our neighborhood of the Milky Way. They could be an abode of life.

We’ve plundered Earth, what’s next?

Dear Cheap Astronomy – If we did colonize the Solar System, what would we do with the different planets?

It remains to be seen if we will spread out across the solar system. While we starting to feel more confident about avoiding a mass extinction asteroid strike, a super-volcano eruption could just as easily end civilization as we know it. There’s also the more mundane scenario of where our population keeps growing, we run low on resources and then fight a bunch of wars over what’s left, pretty-much trashing what’s left of the ecosystem in the process.

Dear Cheap Astronomy – If we colonized the Solar System, Part 2

In part 2, we are looking into the far future which has access to speculative technologies, which may or may not come to pass. Indeed, as we stated in Pt. 1 we may never get beyond leaving a few footprints on our local satellite before civilization as we know it collapses. But if we assume the rise of technology can be kept on its current trajectory indefinitely, then sure, all sorts of things could become possible.

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.

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.

- **Highlight:** *Science fiction's balance between storytelling and science accuracy:* "The story is more important than getting the science 100% right, but doing both creates a deeper experience."

Mike Simmons is the founder of Astronomy for Equity ( https://bmsis.org/astro4equity/ ). Others on the team, including people around the world in astronomy and space exploration, authors and philosophers, designers and artists and more will be added as the website is developed.

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.

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.

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:

- 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.

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!

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.

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:

- 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!

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!

George’s Random Astronomical Object presents the planetary nebula NGC 7094.  While this object may look fairly typical in terms of planetary nebulae, the star at the center is not quite a dead white dwarf yet.

Brief biography: 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.

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.

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.

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.

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.

Today’s guest: 

Dr. Jarita Holbrook (https://en.wikipedia.org/wiki/Jarita_Holbrook,  Harvard Smithsonian Ctr. for Astrophysics, Univ. of Edinburgh, Univ. of the Western Cape) tells the story of the Astronomy Oral History Project. You will also hear some great advice for navigating graduate school and your post-doc years! (Hint: learn to write effective grant applications) Also:  https://www.youtube.com/user/astroholbrook  

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.

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.
