Astronomy Cast Ep. 742: Atmospheric Gravity Waves
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.

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

Travelers in the Night Eps. 297E & 298E: Weird Centaur & Psyche Water
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. 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.

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.

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. From January 2024. Today's 2 topics: - A research project whoes goal is to explore if it would be possible, on short notice, to pulverize a small asteroid so that it would not enter the Earth’s atmosphere as a single object perhaps saving humanity from an very expensive sonic boom. - My Catalina Sky Survey teammate David Rankin was being filmed and interviewed by the NASA 360 crew at our 60 inch telescope on Mt. Lemmon, Arizona when he discovered a scary space rock moving through the constellation of Aquarius at 13 mi/s.Rest assured that asteroid hunters will carefully keep track of 2023 VS3 to make sure that its orbit does not change to make it a threat in the distant future as it passes near to Earth, Mars, and other asteroids.

H’ad Astra Historia Ep. 201 – The 2025 HAD Osterbrock Book Prize

H’ad Astra Historia Ep. 201 – The 2025 HAD Osterbrock Book Prize
Today’s guest is Dr. Seb Falk is the recipient of HAD’s 2025 Osterbrock Prize for his book “The Light Ages: the Surprising Story of Medieval Science”. His exceptionally well-written book takes the reader on a learning journey with the 14th century Benedictine monk John Westwyk who, at the end of his career in 1392, wrote an instructional manuscript in Middle English for an equatorie to compute a planet’s location. Originally discovered in 1951 and attributed to Chaucer, 30 years later the manuscript’s author was identified as Westwyk. Based on years of meticulous scholarly research, Falk teaches the reader detailed, and progressively complicated, 14th century science in this thoroughly pleasurable story about Westwyk’s life. H’ad astra historia is the official podcast for the Historical Astronomy Division of the American Astronomical Society. We’re here to share stories from and about the people who study the stars, planets, and the cosmos. We’ll be hearing from individuals who not only study the history of astronomy, but also those who lived it, who were “in the room” during pivotal events within the last 50 years or so. Podcaster: Loretta Cannon (an AAS affiliate via Rose City Astronomers) is a science-and-word-nerd who really likes the stars. She quite enjoys working as HAD’s podcaster, bringing astronomy stories to you. We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

Astronomy Cast Ep. 740: Sneaky Stars!
Streamed live on Jan 13, 2025. Why stars can’t be trusted! If you’re an astronomer you depend on accurate observations of stars, but there’s a problem. Stars are sneaky! Changing in size, brightness, color, they hide their chemistry, their age and even their companions from all but the cleverest observers. Stars explode precisely when they intend to. Betelgeuse took a brightness plunge, T CrB refused to go nova, and other failures to be predictable irk observers for good reasons. Let's talk about it. SUPPORTED BY YOU!

Exoplanet Radio - TESS's Breakthrough Discovery of Long-Period Exoplanets TOI 4600 b and c
Fron September 7, 2023. Hosted by Tony Darnell. Human beings have discovered over five thousand five hundred exoplanets. Over 80 percent of them have orbits shorter than 50 days which would place them at over twice as close to their star as Mercury is to the Sun. Some are even closer. Recent observations from TESS however have found one with an orbit of 82 days and another measured in hundreds of days.

Travelers in the Night Eps. 775 & 776: 3 Close Approaches & Naming Asteroids and Comets
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. From December 2023. Today's 2 topics: - During a six hour period three small space rocks passed through the Earth-Moon system. At discovery 2023 TO4 was in Pegasus, 2023 TD7 was in Aries , and 2023 TQ3 was in Eradanus. - Every year a significant number of comets and asteroids are discovered by amateur astronomers with modest equipment.Their reward is satisfaction and the right to name their discovery.

NOIRLab - The Fastest Feeding Black Hole

NOIRLab - The Fastest Feeding Black Hole
Supermassive black holes exist at the center of most galaxies, and modern telescopes continue to observe them at surprisingly early times in the Universe’s evolution. It’s difficult to understand how these black holes were able to grow so big so rapidly. But with the discovery of a low-mass supermassive black hole feasting on material at an extreme rate, seen just 1.5 billion years after the Big Bang, astronomers now have valuable new insights into the mechanisms of rapidly growing black holes in the early Universe. In this podcast, Hyewon Suh and Julia Scharwächter discuss the discovery of LID-568, a black hole that is feeding at 40 times the theoretical limit. Bios: Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona. Hyewon Suh’s research mainly focuses on the multi-wavelength studies of Active Galactic Nuclei and their host galaxies to understand the growth of black holes in the context of galaxy evolution. While the deep, large-area extragalactic surveys have greatly enriched our knowledge of the early universe, there are several missing pieces in the understanding of the formation and the growth of supermassive black holes. She is interested in the most energetic and obscured phase of accreting black holes to explore the formation of the first accreting black holes, and to provide the crucial observational constraints on a hidden phase in the early universe. Julia Scharwächter’s main research area is the (co-)evolution of galaxies and their supermassive black holes. She is interested in studying the role of AGN feedback and the nature of black hole mass-host galaxy scaling relations. Her observational projects mostly aim at spatially resolved studies of galaxy nuclei in the nearby Universe. She uses 3D spectroscopy in the optical, near-infrared, and at millimeter wavelengths to probe the stellar and gas component in galaxies, with a special focus on gas-kinematic black hole mass measurements and gas excitation/kinematics around AGN. She is also interested in galaxy dynamics and galaxy merger simulations using N-body/SPH codes.

EVSN - End-Permian Extinction Lasted 10X Longer on Land Than in Water
From April 27, 2021. The biggest mass extinction event on Earth occurred at the end of the Permian period, resulting in the extinction of 95% of marine life and 80% of terrestrial life. Now, scientists have found that the terrestrial portion of the event lasted nearly ten times as long as the ocean version. Plus, a spaghettified star, the search for Moon Trees, all about Mars, and new works on dark matter and dark energy.
