Travelers in the Night Eps. 807 & 808: Moon Orbit Crossers & Global Auroras on Mars

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 2024. Today's 2 topics: - During a recent 60 day period of time 23 space rocks came closer to Earth than our Moon. - When the Earth enters a stream of high speed protons and other charged particles in the solar wind or our home planet is impacted by a solar coronal mass ejection the Earth’s strong magnetic field acts a a shield. Mars on the other hand lacks an Earth-like magnetic field and thus has little protection from solar storms.   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 - A Stellar Companion for Betelgeuse

Astronomers have discovered a companion star in an incredibly tight orbit around Betelgeuse using the NASA and U.S. National Science Foundation-funded ‘Alopeke instrument on Gemini North, one half of the International Gemini Observatory, partly funded by the NSF and operated by NSF NOIRLab. In this podcast, Dr. Steve Howell describes the possible discovery of this long sought after companion and future observations research into this type of star system.    Bios:  - Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona. - Dr. Howell has spent over 40 years as a professional astronomer. During that time, he developed digital (CCD) imaging instrumentation and data reduction techniques space and ground-based telescopes, performed research in a wide variety of astronomical areas and collaborated with hundreds of astronomers world-wide. His areas of expertise are instrumentation, interacting binaries, stellar evolution, and exoplanets. Howell’s professional work has providing community service to the field of astronomy as well as formal and informal STEM education.

Astronomy Cast Ep. 235: Einstein

http://www.astronomycast.com/archive/ From October 17, 2011. What can we say about Einstein? Albert! Freaking! Einstein! Lots, actually. In this show we’re going to talk about the most revolutionary physicist… ever. He completely changed our understanding of time, and space, and energy, and gravity. He made predictions about the nature of the Universe that we’re still testing out.   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. 805 & 806: Very Close Miss & Distant PHA

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, 2024. Today's 2 topics: - During a recent 60 day period asteroid hunters observed 23 asteroids which came closer to us than our Moon. Six of them passed closer to the Earth’s surface than 22,236 miles which is the distance to our communication satellites.   - It is hard to obtain time on the 8m Gemini South Observatory telescope on Cerro Pachon in Chile and the Large Binocular Telescope with its twin 8m mirrors on Mt. Graham, Arizona since they are among the largest telescopes in the world. My Catalina Sky Survey teammate Kacper Wierzchos wrote a scientifically competitive proposal to obtain the time to track the potentially hazardous asteroid 2016 PR38 on both of these telescopes when it was near its furthest point from our Sun and thus much too faint for the telescopes asteroid hunters routinely use.   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!

Astro Interviews - Fraser Cain

From August 19, 2017. Your audio editor, Richard Drumm, interviewed Astronomy Cast’s co host Fraser Cain. The idea was to interview him before and after the total solar eclipse that was upcoming, and get his before and after impression of the event. Unfortunately the clouds at Carbondale, Illinois, had other plans. Fraser & Pamela were at SIUC’s Stadium and Richard was 2 miles away at the SIUC School of Agricultural Sciences. Richard had a clear sky and Fraser & Pamela did not. This unfortunate turn of events blew the interview’s main purpose to bits, so to speak. Even so, the interview is informative and worth a listen!   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!

EVSN - Saturn’s Rings Are Made of a Broken-up Moon

From September 16, 2022. Using computer simulations, researchers have pieced together a possible scenario where Titan caused another of Saturn’s moons to break up and become the beautiful ring system we see today. Plus, organic molecules on Mars, the death of the dinosaurs, and a review of Lightyear on Disney+.   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!
