    Deep Astronomy - Discoveries of the Webb Space Telescope: Webb's First Deep Field

    https://www.youtube.com/watch?v=WvdZpZuz-WQ Hosted by Tony Darnell. From  Feb 13, 2025. The deep fields taken by the Hubble Space Telescope are now legendary.  Astronomers used the most complicate and expensive instrument ever put into space to stare at nothing, a very risky move, but one that paid off.   What happened when we did the same thing with the James Webb Space Telescope?   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. 778: Dyson Swarms

    https://www.youtube.com/watch?v=cySk8O0iVjU Hosted by: Fraser Cain (@frasercain ) and Dr. Pamela L. Gay (@CosmoQuest ) Streamed live on Jan 5, 2026. Freeman Dyson asked a fascinating question. What would it look like if a civilization was using all the energy coming from their star? And what form would this take? This introduced the concept of a Dyson Sphere, or more realistically, a Dyson Swarm surrounding a star. But if you're skeptical about the concept, you're in good company.   This show is supported through people like you on Patreon.com/AstronomyCast  In this episode, we'd like to thank: Burry Gowen, Eric Lee, Jeanette Wink, Michael Purcell, Andrew Poelstra, David, David Rossetter, Ed, Gerhard Schwarzer, Jason Kwong, Joe McTee, Sergey Manouilov, Siggi Kemmler, Sergio Sancevero With special guest star Stella!   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. 845 & 846: Mighty Schmidt & Bright Nights

    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 April 2025. Today's 2 topics: - On a single February night my Catalina Sky Survey teammate Jacqui Fazekas reported  the discovery of 5 Earth approaching objects using our small but mighty Schmidt telescope on Mt. Bigelow, Arizona.Rest assured that on any given night there are asteroid hunters on the look out for seriously dangerous space rocks. - One little known and infrequently observed phenomenon in the natural night sky are "bright nights" during which observers have reported being able to read a book  when both the Sun and Moon are both well below the horizon.   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 - Fast Spinning Asteroids From the Rubin Observatory

    As part of the NSF–DOE Vera C. Rubin Observatory First Look event in June 2025, Rubin announced that it had observed thousands of asteroids cruising about our Solar System, about 1,900 of which have been confirmed as never-before-seen. Within the flurry, a team of astronomers has discovered 19 super- and ultra-fast-rotating asteroids. One of these is the fastest-spinning asteroid larger than 500 meters (0.3 miles) ever found. In this podcast, Dr. Sarah Greenstreet discusses these fast spinning asteroids and what makes the Rubin Observatory ideal for discovering these types of objects.   Bios:  - Rob Sparks is in the Communications, Education and Engagement group at NSF's NOIRLab in Tucson, Arizona. - Sarah Greenstreet is a tenure-track assistant astronomer at the NSF National Optical-Infrared Astronomy Research Laboratory (NOIRLab) and an affiliate assistant professor in the University of Washington's Department of Astronomy. She is also a member of the Rubin Observatory Community Science Team and has served as the Lead for the Rubin Observatory Solar System Science Collaboration's Near-Earth Objects and Interstellar Objects Working Group for the past seven years. Prof. Greenstreet's research program broadly focuses on orbital dynamics, characterization, and impacts of small bodies across the Solar System, with a particular focus on the rarest and most unusual asteroids.
