    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.

  • 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.

    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.

    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.

    This is a re-run of episode 29 of The Cosmic Savannah in anticipation of an upcoming interview with Prof Matthew Bailes so all our listeners can get up to speed about everything to do with Neutron Stars!

    We are firstly joined by Prof. Matthew Bailes from the Centre for Astrophysics and Super computing at Australia’s Swinburne University of Technology. Matthew is a world expert on pulsars and the Director of the “OzGrav” ARC Centre of Excellence for Gravitational Wave Discovery.

    Matthew chats with is us about pulsars, gravitational waves and some of the incredible science we can expect from projects such as Meertime. MeerTime will use the MeerKAT telescope to explore fundamental physics and astrophysics using radio pulsar timing.

    We’re then joined by Katia Moskvitch, who was the 2019 British Science Journalist of the Year and the 2019 European Science Journalist of the Year! Katia tells us about a her new book “Neutron stars: The Quest to Understand the Zombies of the Cosmos.” This popular science book is written for a general audience and describes the fascinating and bizarre existence of neutron stars and pulsars.

  • 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.

    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.

  • From August 4, 2020.

    Join us today as we talk about newly released research that suggests the waters on ancient Mars were subglacial and not free-flowing. Also, a black hole goes dormant and star formation goes wild. Meanwhile, computer models show that unequal neutron stars colliding may cause a big “bang” that can be detected on Earth.
