From March 10, 2021.
A new study examines the formation of rocky worlds from dust particles containing ice and carbon, increasing the possibility that our own Milky Way galaxy could be filled with aquatic planets similar to Earth. Plus, a simulation of the Milky Way-Andromeda collision and an overview of asteroid Apophis.

From Wikipedia:
“Brother Guy J. Consolmagno, SJ (born September 19, 1952), is an American research astronomer, physicist, religious brother, director of the Vatican Observatory, and President of the Vatican Observatory Foundation.
His research is centered on the connections between meteorites and asteroids, and the origin and evolution of small bodies in the Solar System. In addition to over 40 refereed scientific papers, he has co-authored several books on astronomy for the popular market, which have been translated into multiple languages.
During 1996, he took part in the Antarctic Search for Meteorites, ANSMET, where he discovered a number of meteorites on the ice fields of Antarctica. An asteroid was named in his honour by the International Astronomical Union, IAU in 2000 - 4597 Consolmagno.

It looks as though the European Southern Observatory is caught in an American light pollution pincer…starlink above and now the threat of an American industrial complex as a neighbour. Is this the end?
We have eclipse news, launch round up and the usual inane chatter from Jeni & Paul.

From September 12, 2023.
Hosted by Tony Darnell.
Based on our experience here on Earth, we know life here to be tenacious and ubiquitous. Even in the harshest climates, if we look hard enough, we can usually find some sort of life there. We are hoping the same is true on worlds around other stars, and recent research has begun looking into the question of whether life on other worlds could exist in the most inhospitable environs: the terminator zone of tidally locked planets.

From January 8, 2007.
We’re finally ready to deal with the topic you’ve all been waiting for: Schwarzschild swirlers, Chandrasekhar crushers, ol’ matter manglers, sucking singularities… You might know them as black holes. Join us as we examine how black holes form, what they consume, and just how massive they can get.

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.
- 2016 was another record year for asteroid hunters during which we discovered 1,894 new Earth approaching objects. My team, the NASA funded, Catalina Sky Survey, led the pack with 931 Near Earth Asteroid discoveries.
- An example that a relatively large space rock can approach the Earth suddenly started with what appeared as a bright star moving across the images that I had just obtained with the Catalina Sky Survey's 60 inch telescope on Mt. Lemmon, Arizona.

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.

We have dust storms on Earth and of course the famous dust storms on Mars. There are even dust storms on Titan. What causes these storms and how do they work differently on the worlds in the solar system. But what about the exoplanets?
The bane of solar panels, humans, and robots, dust storms have a way of picking up steam (or at least dust) all over 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:
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.

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.We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

From June 15, 2021.
Contrary to the destructive role supermassive black holes are thought to play in the lives of stars, it turns out that certain types of galaxies benefit from black holes clearing the way and keeping star formation going. Plus, lightning at the edge of space, a landslide in the Himalayas, and an interview with Dr. Darby Dyar and Dr. David Grinspoon about the recent selection of three different Venus missions.

Our very big home.
Dear Cheap Astronomy – Just why?
Asking why the Universe is doesn’t have to be a spiritual inquiry into purpose. We can look across the Universe and observe that things happen in very predictable patterns, following determinable and repeatable pathways of cause and effect which are always in the general direction of increasing entropy.
Dear Cheap Astronomy – Will we ever make contact with aliens in another star system?
Here at Cheap Astronomy, we don’t think astronauts, taikonauts or any nauts will ever be exploring other worlds in person. There’s nowhere we could go outside the Solar System within a lifetime and generation starships would just be a nightmarish Lord of the Flies in a tin can.

I’m sure you’ve heard the news, asteroid 2024 YR4 has a tiny chance of hitting Earth in 2032. How do astronomers discover these dangerous asteroids, measure their future impact risk and track the changes over time? When should we panic? New asteroids are found every day, and every day we learn that those asteroids don't have any murderous intentions. But how do we learn that? In this episode we dig into asteroid orbital determination.

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.
