The 365 Days of Astronomy

https://www.youtube.com/watch?v=xBJ4LBFxqb8 Streamed live on Apr 7, 2025. Hosted by: Fraser Cain and Dr. Pamela L. Gay. Even empty space isn’t empty. It’s filled with the quantum fluctuations of spacetime itself. Which can be measured with famous experiments like the Casimir Effect. There is a surprising amount of energy in space itself, which has led to some interesting theories about how the future of the Universe might evolve. You can't get something from nothing but sometimes that nothing is something you can get something from.   SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

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 February 2024. - Centaurs have long puzzled astronomers since they have traits in common with both asteroids and comets. - So far asteroid hunters have discovered approximately half of the 5,000 PHAs which are likely to exist. Asteroid hunters will continue to search the sky to discover dangerous asteroids 50 years before impact so that humans can either deflect or pulverize them.   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!

Hosted by Rob Sparks. Description: The Dark Energy Spectroscopic Instrument (DESI) at Kitt Peak National Observatory has been collecting spectra of millions of galaxies to better understand dark energy, the mysterious force that is causing the expansion of the universe to accelerate. The DESI collaboration recently released results based on the first three years of data that indicate dark energy is not a constant force. In this podcast, NOIRLab’s Joan Najita discusses DESI and its groundbreaking results.    Bios: Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona. Dr. Joan Najita is an astronomer at NOIRLab, NSF’s research and development center for ground-based optical and infrared astronomy. She studies the origins of stars and planets and the life histories of the Milky Way and nearby galaxies. A long-time advocate for "highly multiplexed spectroscopy" (i.e., facilities like DESI), she also studies how discoveries are made in astronomy, and works to develop new tools and facilities that sustain discovery.   Links: NORLab Press Release: https://noirlab.edu/public/news/noirlab2512/ DESI’s public webpage: https://www.desi.lbl.gov/ - DESI’s YouTube channel, which features playlists of DESI talks from the March 2025 APS meeting and additional talks showcasing the BAO results:  https://www.youtube.com/@DESISurvey - Access the DESI data release through Astro Data Lab https://datalab.noirlab.edu/desi/index.php 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!

Discover the intriguing world of space mining, where the universe is a treasure trove of resources waiting to be tapped. Navigate the humorous challenges of extracting materials from asteroids and comets. Then, plunge into the complexities of time travel, examining how speed and gravity can warp our perception of time. Explore the ethical dilemmas and theoretical hurdles that come with the idea of bending time. Ultimately, it questions whether we should fix the past or learn from it as we journey into the future.

Paul Hill and Dr. Jenifer “Dr. Dust” Millard host.  Damien Phillips, John Wildridge and Dustin Ruoff produce. Episode 154. Has NASA been Trumped? We try to keep it upbeat this month with tales of blackholes, definitions of moons, and solar system science but unfortunately the fate of NASA and American science currently hangs in the balance…   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!

Supernovae could soon reveal their secrets even before the light show begins, thanks to a network designed to detect neutrinos. This advanced early warning system aims to alert astronomers about an impending explosion, potentially allowing telescopes to zero in on the action in real-time. The conversation dives into the challenges of tracking disappearing stars and the cosmic phenomena they may hint at, including black holes. Enhanced detection technologies promise to deepen our understanding of these stellar fireworks.
