https://www.youtube.com/watch?v=evnwMG85VeY Streamed live on Mar 10, 2025. Hosted by: Fraser Cain and Dr. Pamela L. Gay Most planets orbit stars. That’s the rule, right? Well, maybe not. In fact the vast majority of planets could be floating freely through the Milky Way. Today we’re gonna talk about rogue planets. Sometimes planets just go rogue. Let's learn about planets living free from stars.    Show Notes: Earth's Dust Storms Mars' Global Dust Storms Dust Storms on Titan Potential Dust Storms on Exoplanets   SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

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. T

Hosted by Andy Poniros. 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.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as

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.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

https://www.astronomycast.com/archive/ 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.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

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.    We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

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.

From February 19, 2025. Let's take a fast-paced journey thru all that's new in space and astronomy, including a potentially killer asteroid, a new look at the history of Earth's water, and a mini-quasi-moon, along with a deep dive into climate change, and tales from the launch pad.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

https://www.youtube.com/watch?v=iTaLgpL5NFI Streamed live Feb 24, 2025. 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.   Hosted by: Fraser Cain and Dr. Pamela L.

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 Marrake

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 fro

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.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
