    Guide To Space - AstroClipper: Plans For A Two-Stage, Fully Reusable Spaceplane

    https://www.youtube.com/watch?v=qWfkW2y-hAQ From Oct 15, 2019. Even as the first rockets were launched into space decades ago, aerospace knew it was a wasteful process. Rocket stages, motors, and complex equipment crashed into the ocean or burned up in the Earth’s atmosphere. Could spaceplanes bring the costs down? Flying to orbit with a combination of jet engines and rockets and then safely re-enter the Earth’s atmosphere again.   Single-stage to orbit spacecraft and spaceplanes have always seemed out of reach, and actually not that practical. But what about a two-stage, fully reusable spaceplane? Exodus Space Corporation has been secretly working on this concept for a decade now, and what they’re proposing is pretty revolutionary.   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. 767: Black Holes in Extreme Circumstances

    https://www.youtube.com/watch?v=mCqRhiApwMQ Season 19 Hosted by: Fraser Cain and Dr. Pamela L. Gay Streamed live on Oct 6, 2025. You can only describe a black hole by its mass and its spin. And maybe it’s charge. But allow us to propose a new criteria: the personal experience. Some black holes have seen things… Experienced the laws of physics at their most extreme. And today we’ll tell their stories. The more of the sky we observe, the more bizarre situations we find black holes in. Let's explore!   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, David Truog, Ed, Gerhard Schwarzer, Jason Kwong, Jeanette Wink, Michael Purcell, Olger, Sergio Sancevero, Sergey Manouilov, Siggi Kemmler, Stephen Veit   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. 339E & 340E: Ice World & Nearby Planets

    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: - Recently Dr. Yossi Shvartzvald led a team which published their discovery of an Earth sized planet using microlensing in the Astrophysical Journal Letters. The newly discovered planet OGLE-2016-BLG-1195Lb orbits a small dim object about 13,000 light years from us. With only 7.8% of the Sun's mass the new planet's star may be a brown dwarf and not a star at all. At about the same distance from its star as we are from the Sun this new planet is likely to be an ice ball world colder than Pluto. - In 2018 the NASA Transiting Exoplanet Survey Satellite nicknamed TESS will be launched and begin a two to three year mission to discover small Earth sized planets orbiting bright stars in the solar neighborhood.   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 - Elusive Cloud Forming Chemicals Found On “The Accident”

    Astronomers have long predicted that the cloud forming chemical should be found in the atmospheres of brown dwarfs and gas giants. Silane had eluded detection until now. In this podcast, Dr. Aaron Meisner recounts how silane was discovered in the atmosphere of a brown dwarf nicknamed “The Accident”. The Accident (WISEA J153429.75-104303.3) was discovered by citizen scientist Dan Caselden, who was using an online program he built to find brown dwarfs in NEOWISE data.   Bios:  Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona. Aaron Meisner is an astronomer at NSF NOIRLab affiliated with the Vera C. Rubin Observatory, and also a 2025-2026 Radcliffe Fellow at Harvard University. He specializes in building astronomical maps using large data sets at visible and infrared wavelengths.  These maps are used to search for moving celestial objects, like new neighbors to the Sun and hypothesized planets in the far reaches of our own solar system. To this end, Aaron co-founded the popular Backyard Worlds: Planet 9 citizen science project and the Backyard Worlds: Cool Neighbors project.   Press release: https://noirlab.edu/public/news/noirlab2526/?nocache=true& https://www.jpl.nasa.gov/images/pia24578-an-accidental-discovery/ https://aasnova.org/2021/07/02/observing-the-accident-an-enigmatic-brown-dwarf/   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!
