The 365 Days of Astronomy

• UNAWE Space Scoop: Lonely Planet — The Hungriest Exoplanet

  https://spacescoop.org/en/scoops/2524/lonely-planet-the-hungriest-found-in-space/ Hosted by Richard Drumm, our editor. You've probably heard of exoplanets. Planets that orbit stars other than our Sun. But did you know that there are objects with a mass similar to a planet that float free in space, that don't orbit a star? These lonely wanderers are called rogue planets.   Recently, a team of astronomers discovered a very special one in the southern constellation Chameleon. The rogue planet is named Cha (for Chameleon) 1107-7626 and is located about 620 light-years away. It has a mass of 5 to 10 times that of Jupiter and is still growing!    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!

• Exoplanet Radio - Epsilon Indi Ab: A Twin of Jupiter

  Hosted by Tony Darnell. From August 17, 2024. An international team of astronomers has directly imaged this exoplanet, one of the coldest ever seen.  The team observed Epsilon Indi Ab using the coronagraph on Webb's Mid-Infrared Instrument. Only a few tens of exoplanets have ever been directly imaged by space- and ground-based observatories.  These observations are ushering in a completely new era in exoplanet research.   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!

• Astronomy Cast Ep. 770: The Ethics of Mars Exploration

  https://www.youtube.com/watch?v=14QKJkt3cIE Streamed live on Nov 3, 2025. Hosted by: Fraser Cain and Dr. Pamela L. Gay. It is arguable that humanity now has the technological ability to live on Mars. It would be done at enormous expense and sacrifice, and there are some tricky problems that we haven't solved yet. Although we could live on Mars, should we? There is a famous quote from Jurassic Park: "Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should." This concept is played out across the sciences, and in planetary exploration, it requires us to ask, all because we can launch humans toward Mars, should we?   This show is supported through people like you on Patreon.com/AstronomyCast In this episode, we'd like to thank: Andrew Poelstra, BogieNet, Brian Cagle, Burry Gowen, David, David Rossetter, Ed, Gerhard Schwarzer, Jason Kwong, Jeanette Wink, Michael Purcell, Sergey Manouilov, Siggi Kemmler, Sérgio Sancevero   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!

• Travelers in the Night Eps. 347E & 348E: Life's Parts & 2 Headed Space Worm

  Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org From July & August 2025. Today's 2 topics: - 24 hours a day, 16,600 feet above sea level in the high dry desert of northern Chile, the 66 antennas of 1.4 billion dollar Atacama Large Millimeter/submillimeter Array or ALMA receives signals located between the infrared and radio portions of the electromagnetic spectrum. The waves that ALMA receives have a length which is about the same as the thickness of a dime. The pattern of present and missing wavelengths in these signals contains the characteristic spectral signatures of the complex molecules that form the basis of living organisms.   - Humans are moving towards a day when there are space colonies in orbit, on the Moon, and the planet Mars, places where the force of gravity ranges between zero and 38% of what we experience every day. What effect will such different environments have on the regeneration of liver, skin, and other human body organs?    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!
