The 365 Days of Astronomy

• Astronomy Cast Ep. 18: Black Holes Big & Small

  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!

• Travelers in the Night Eps. 307E & 308E: Asteroids 2016 & Suddenly Bright

  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.    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!

• NOIR Lab - The Largest Radio Jet In the Early Universe

  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.   Links: NORLab Press Release: https://noirlab.edu/public/news/noirlab2506/ Gemini Observatory: https://www.gemini.edu/ NOIRLab social media channels can be found at https://www.facebook.com/NOIRLabAstro https://twitter.com/NOIRLabAstro https://www.instagram.com/noirlabastro/ https://www.youtube.com/noirlabastro   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!
