The 365 Days of Astronomy

• Astronomy Cast Ep. 742: Atmospheric Gravity Waves

  https://www.youtube.com/watch?v=voStvJmLZis Streamed live on Jan 27, 2025. Hosted by: Fraser Cain and Dr. Pamela L. Gay Gravity Waves ... not gravitational waves ... move atmospheres and make pretty clouds. Have you ever looked up into the sky and seen bizarre cloud formations that look like waves on the ocean? These are gravity waves. Not to be confused with gravitational waves, and they’re caused by a balance of buoyancy and gravity. And of course these have been seen across the solar system.    SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

• Travelers in the Night Eps. 297E & 298E: Weird Centaur & Psyche Water

  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 August 2024. Today's 2 topics: - Richard Kowalski discovered  2016 WM48, a Centaur. Centaurs are named after the mythical beasts which were half human and half horse perhaps because they have characteristics of both asteroids and comets. 2016 WM48, is about a mile in diameter. We don't know if it has rings, tiny moons, or a gas cloud surrounding it as some other Centaurs do. 2016 WM48 must have had a catastrophic collision in the past few million years which put it on a very elliptical path which is tipped at 60 degrees or so to the solar system's plane. - The asteroid Psyche may be one of the most expensive pieces of real estate in the solar system. It is a small world about 116 miles in diameter and is composed of almost pure nickel-iron metal. It is located in the asteroid belt between Mars and Jupiter. Scientists find evidence that Psyche may be the exposed core of a planet which was destroyed by collisions as it was trying to form long ago.   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!

• Last Minute Astronomer - February Episode

  Hosted by Rob Webb. Full text available at the Cosmos Safari Blog.   February 2025 is a phenomenal continuation of January’s planetary-ness! You’ll get chances to see all the planets before going to bed and a conjunction of Mercury & Saturn.   Hi everybody, I’m Rob, your Last Minute Astronomer, bringing astronomy to normies and nerds, with little time to spare. We’ll start by talking about this month’s big events, then highlight the naked eye planets, and finish up with the lunar phases, so you can plan ahead better than me.   LUNAR CLOSE ENCOUNTERS  The Moon will be traveling across the sky as normal, passing by some planets at particular times.  1st - 2nd - Saturn has dipped below Venus in the sunset sky by about 12°, and a very thin crescent Moon joins in on the 1st, within 3° of Venus. Then, on Feb 2nd, the Moon, Venus, and Saturn make a string of objects just after sunset in the SW. 6th - Find the Waxing Gibbous Moon just about 5° above bright Jupiter moving West throughout the night, setting just before 3:30am. 9th - The Moon will start out the night just 2˚ from Mars, moving further away throughout the night, setting around 6am.   Music was produced by Deep Sky Dude and used with permission.    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!
