Travelers in the Night Eps. 313E & 314E: Greg’s Destination & Whoppers

30 mars 2025 | 6 min

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:

- A winter storm hit Mt. Lemmon, Arizona closing access to the observatory by blowing over trees and producing large snow drifts. After the Mountain Operations Crew cleared the road, my Catalina Sky Survey teammate Greg Leonard was able to make his way to the top and discover an asteroid which could be visited by human astronauts. Greg's new 120 foot diameter space rock, named 2017 BV93, spends most of its time between Earth and Venus as it orbits the Sun once every 346 days.

- Recently, my Catalina Team Captain Eric Christensen discovered a potentially hazardous 3,000 foot diameter asteroid, 2017 CH1. Asteroid hunters are discovering less than one asteroid of this size or greater per month. Eric's discovery, 2017 CH1, has an orbit which can bring it to about twice the Moon's distance from planet Earth. Although it will not come anywhere near Earth in the foreseeable future, asteroid hunters will continue to monitor 2017 CH1's orbit to make sure that it remains no threat to planet Earth.

H’Ad Astra Historia Ep. 203: Interstellar Part 1

27 mars 2025 | 37 min

Today’s guest: Dr. Jamie Rankin, Voyager Deputy Project Scientist, talks with us today about all things Interstellar. She is also an Associate Research Scholar and Lecturer in Space Physics at Princeton University. NASA-JPL continues to communicate with both Voyagers 1 and 2 as they explore interstellar space. Closer to home, IBEX and three soon-to-be-launched new spacecraft study the protective bubble of our star system from the inside, while also investigating our star’s ever-changing effect on Earth.

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.

Guide to Space - Should We Fly to Another Star Soon? Or Wait for Better Technology to Come Along?

26 mars 2025 | 11 min

https://www.youtube.com/watch?v=RXtYUawd4AY

From Feb 14, 2020.

Hosted by Fraser Cain.

It’s hard to really wrap your mind around the vast distances between stars. The fastest spacecraft ever launched into an interstellar trajectory right now is Voyager 1. If it was directed at the nearest star, it would take tens of thousands of years to make the journey across the interstellar gulf.

Even so, groups like Breakthrough Starshot and Icarus Interstellar are working on plans right now to try and send spacecraft to other stars, ideally within our lifetimes.

But we can see how quickly technology is advancing all around us, from materials science to high energy physics, not to mention reusable rockets.

It seems reasonable to ask, should we invest in an interstellar mission now, or wait a few decades or even centuries for better technology to come along which could make the trip much shorter?

Travelers in the Night Eps. 311E & 312E: Comet Johnson & Space Salsa

23 mars 2025 | 6 min

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:

- Comet C2/2015 V2 Johnson was discovered by my Catalina Sky Survey teammate Jess Johnson on November 3, 2015. It travels on a hyperbolic path around the Sun which is highly inclined to the plane where the planets and most of the asteroids travel. Jess's comet's path takes it from deep space into the inner solar system slightly further from the Sun than the planet Mars. Although it will not get closer to the Earth than about 75 million miles it may out gas enough material to make it visible to the naked eye.

- If Lunar and Martian colonists are to have chips and salsa they will need grow their own tomatoes. To test methods to do this German Aerospace Center or DLR has developed the EU:CROPIS satellite which will be launched by a Space-X Falcon 9 rocket into low Earth orbit sometime in 2017. Once in orbit the satellite will be programmed to rotate at two different speeds on its own axis to produce Lunar gravity for 6 months and then Martian gravity for the next 6 months.

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:

- The National Oceanic and Atmospheric Administration has published an extensive data based review, analysis, and summary of the Earth's Climate. 2016 was hotter than 2015 which was hotter than 2014. 2016 is the warmest year the Earth has been in the more than 180 years of record keeping. Overall in 2016 the whole Earth was 1.8 F above the 1951-1980 average. The Arctic in 2016 was 7.2F higher than it was the pre-industrial age.

- Carson Fuls was using the new hundred million pixel camera on our team's Schmidt telescope located on Mt. Bigelow, Arizona, when he discovered 2017 AG13. It passes near the Earth's orbit twice a year on its own 345 day path around the Sun. When Carson spotted it, 9 lunar distances from him it was heading in our direction at about nine and a half miles per second. Three days later it came to less than two times the distance the Moon's distance from us. Less than three weeks later Carson was using the same equipment when he discovered another small space rock, 2017 BH30, which came to a bit more than an Earth's circumference from our home planet.

NOIR Lab - The Largest Radio Jet In the Early Universe

8 mars 2025 | 12 min

Making use of the Gemini North telescope, one half of the International Gemini Observatory, astronomers have characterized the largest-ever early-Universe radio jet. Historically, such large radio jets have remained elusive in the distant Universe. In this podcast, Dr. Anniek Gloudemans discusses how this object was discovered, the follow up observations and what we have learned about radio jets in the early Universe.

Bios:

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

- Anniek Gloudemans is a postdoctoral fellow at NOIRLab working on understanding the formation and evolution of the most massive supermassive black holes in the early Universe. She received her masters degree from the University of Amsterdam in 2019, including an internship at the European Space Agency in 2018. Following this, she obtained her PhD at Leiden Observatory in The Netherlands in 2023, where she studied the low-frequency radio emission of early supermassive black holes. Besides her research, Anniek has a passion for teaching and organizing outreach activities for all ages with a focus on connecting the world through astronomy and raising awareness for climate change.

Astronomy Cast Ep. 746: Dust Storms

3 mars 2025 | 29 min

Travelers in the Night Eps. 305E & 306E: Newborn Planets & Marrakech

2 mars 2025 | 6 min

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:

From October 2024.

- The ALMA radio telescope located in the Atacama desert of northern Chile is able to see the faint millimeter wave length glow emitted by gas molecules and dust particles in the disk of material surrounding the very young star named HD 163296. This solar system in formation is located about 400 light years away in the constellation of Sagittarius. HD 162396's age compared to our Sun is like that of a 3 day old human baby compared to a 65 year old adult.

- A location 9,000 feet above sea level in the Atlas Mountains of Morocco is ideal for an asteroid hunter since the weather is often clear and the skies are dark. It was thus intriguing for me to see that a new asteroid discovery was posted from J43 which is the Morocco Oukaïmeden Sky Survey or (MOSS) located near Marrakech , a name I had not encountered except in the Crosby, Stills, and Nash song "Marrakech Express". The MOSS observatory has team members in Morocco, France, and Switzerland, call themselves amateurs, and produces professional quality results.

Last Minute Astronomer - March Episode

1 mars 2025 | 19 min

March 2025 says goodbye to Saturn, welcomes a total lunar eclipse, and continues hanging out with the rest of the planets. 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 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.

14th - Total Lunar Eclipse

1:09am EST – Partial Eclipse Begins – Just look South to find the Full Moon, and watch as the Earth’s shadow appears to nibble on the Moon from left to right. This phase will last about an hour. (You might hear that the penumbral portion of the eclipse starts before this. While true, it is essentially undetectable with the naked eye.)

2:26am EST – Totality Begins – Now the umbra of the Earth’s shadow is completely engulfing the Moon, and only the light from all the sunrises and sunsets on Earth are illuminating our orbital partner’s surface, making it appear anywhere from dark yellow to orange to red to brown. This phase will last a little over an hour, with maximum eclipse right before 3am.

3:32am EST – Totality ends, Partiality begins again – now the shadow leaves the Moon, starting to expose its surface from the right to left.

4:48am EST – Partial Eclipse Ends

Other things to look for

As the Moon gets darker, more and more stars will be visible
The Moon is right between Leo and Virgo - Virgo is usually tough to find, so take advantage of the darkened Moon.

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 September & October 2024.

Today's 2 topics:

- Collect your own beautiful micro-meteorite sample.

It is estimated that several hundred thousand pounds of left over particles from the formation of our solar system enters the Earth's atmosphere every day with perhaps 10% of the of the total reaching the surface of our home planet. The individual grains of cosmic dust or micro-meteorites as they are also called range in size from the diameter of a human hair to twice the thickness of a dime.

- To discover what would happen if an asteroid were to strike a large body of water, Dr. Galen Gisler led a team of scientists who used high performance computing facilities at Los Alamos National Laboratory to calculate and visualize a 3-D model of an asteroid entering the Earth's atmosphere over one of the world's oceans. These efforts won them the Best Visualization and Data Analytics Showcase award at Supercomputing 2016. Reality is that what happens depends upon the mass, size, speed, angle of approach, and composition of the impacting object. Galen's group of scientists documented the hunch that since an asteroid strikes the water at a single point, it only effects the immediate region around the impact point, whereas to create a tsunami, you need something like an under water landslide which disturbs an entire water column from the ocean floor to the surface.

From Dec 30, 2022.

We say farewell to NASA's Insight mission on Mars. This lander spent 6 years on the Martian surface examining the interior of the planet. It discovered that Mars is not geologically dead as we previously thought. It discovered that Mars has a larger core than we thought, its magnetic field was stronger than we thought and the crust is thinner. And in typical NASA fashion, it made us all sad to think of the little fella dying in the cold Martian dirt. The heartless swines!

Travelers in the Night Eps. 297E & 298E: Weird Centaur & Psyche Water

2 februari 2025 | 6 min

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.

Last Minute Astronomer - February Episode

1 februari 2025 | 12 min

Hosted by Rob Webb.

Full text available at the Cosmos Safari Blog.

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.

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.

H’ad Astra Historia Ep. 201 – The 2025 HAD Osterbrock Book Prize

23 januari 2025 | 48 min

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.

NOIRLab - The Fastest Feeding Black Hole

11 januari 2025 | 13 min

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.

19 december 2024 | 54 min

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. actualastronomy@gmail.com

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.

NOIR Lab - DESI Tests Gravity at Cosmic Scales

14 december 2024 | 12 min

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.

Last Minute Astronomer - December Episode

7 december 2024 | 21 min

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.

Astronomy Cast Ep. 735: Albert Einstein

2 december 2024 | 37 min

Travelers in the Night Eps. 293E & 294E: Bright and Bald & 200 Yards of Trouble

1 december 2024 | 6 min

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.

H’ad Astra Historia Ep. 107: Where No One Has Gone Before

28 november 2024 | 38 min

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.

Cheap Astronomy - Dear CA #111: Practicalities

14 november 2024 | 15 min

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.

NOIR Lab - Quasar In The Early Universe

9 november 2024 | 10 min

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.

Last Minute Astronomer - November Episode

2 november 2024 | 15 min

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.

Dr. Jarita Holbrook continues with her story of the AAS’ Astronomy Oral History 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.

Cheap Astronomy - Implausible Engineering Ep. 2: Embracing Your Inner Robot

23 oktober 2024 | 15 min

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.

Travelers in the Night Eps. 291E & 292E: Tiny Atira & Ethics and Mars

20 oktober 2024 | 6 min

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?"

Travelers in the Night Eps. 289E & 290E: Murky & Egg Rock

13 oktober 2024 | 6 min

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.

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!

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.

EVSN Special - Quasi Moon Naming Contest!

27 september 2024 | 29 min

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.

H’ad Astra Historia - Ep. 105: Astronomy Oral History Project, Part 1

26 september 2024 | 38 min

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.

Travelers in the Night Eps. 287E & 288E: Sensing A Comet & Close One

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.

EVSN - Mars is the Future, the Day the Dinos Died, a Star's Death in 3 Acts, & More!

Cheap Astronomy - Dear CA #109: Planets

12 september 2024 | 15 min

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.

Last Minute Astronomer - September Episode

7 september 2024 | 15 min

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 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

Travelers in the Night Eps. 285E & 286E: Sporadic Geysers & Visitors From Afar

25 augusti 2024 | 6 min

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.

Astronomy Cast Ep. 8: Meteor Showers. Yes, The Sky Is Falling!

Last Minute Astronomer - August Episode

3 augusti 2024 | 15 min

What is gracing the August 2024 skies? A rare conjunction of Jupiter & Mars, great conditions for the annual Perseid Meteor Shower, and all the naked-eye planets visible.

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

THE BIG EVENT!

11th – 12th – Perseid Meteor Shower – EXCELLENT year for the Perseids, given the first-quarter Moon sets before midnight. In decent skies, you could watch 60 meteors per hour, and you should be able to see some very bright ones here and there the week before and after. The strategy to observe this year is to get out there whenever you can, but the “wee hours” and the pre-dawn morning on the Monday 12th is when you’ll see the most. The shower is usually technically active from mid-July to late August, so you may see some Perseids in the days leading up to and after the peak as well. Remember, you’re seeing the bits of dust left over from Comet Swift-Tuttle burning up as they crash into the atmosphere at 37 miles per second.

Some advice for watching:

- Find a dark location and lie down in a reclining chair or hammock.

- Look toward Perseus. In the NE, it rises throughout the night until sunrise where it will be almost directly above. That is where the radiant is - where the meteors will appear to be coming from. But you should basically just look UP.

- Check the weather ahead of time 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.

- Make a game of it! Get the kids counting and do a scientific meteor count (IMO).

The Cosmic Savannah - Ep. 59: Construction of the SKA Commences!

27 juli 2024 | 53 min

Hosted by Dr. Jacinta Delhaize & Dr. Daniel Cunnama.

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

We are honoured to be joined by the SKA Observatory Council Chairperson, Dr. Catherine Cesarsky to talk about this momentous occasion.

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.

Dr. Cesarsky was appointed Chair of the SKA Board of Directors in 2017, and her distinguished career spans some of the biggest international astronomy projects of recent years. As Director-General of the European Southern Observatory she oversaw the Very Large Telescope, the start of construction of the Atacama Large Millimeter Array (ALMA) and launched the Extremely Large Telescope project, one of the key astronomical facilities of the coming decades along with the SKA. Among her other prestigious roles, Dr Cesarsky was President of the International Astronomical Union and High Commissioner for Atomic Energy in France. She is known for her successful research activities in high energy and in infrared astronomy and is member or foreign member of science academies over the world, including Europe (Academia Europaea), France (Académie des Sciences), United Kingdom (Royal Society), United States (NAS), Sweden (Royal Swedish Academy of Sciences).
