EVSN - Strange Supernova Appears Cool Before Exploding
From May 6, 2021. Researchers find that the “oddball supernova” of a curiously cool, yellow star was lacking the hydrogen content expected, “stretching what is physically possible.” Plus, finding potentially habitable planets, a gamma ray burst, ash clouds, and a new lunar map in this week’s What’s Up.

Awesome Astronomy - Have Blue Origin Already Lost to SpaceX?
Ralph Wilkins hosts. Damien Phillips, John Wildridge and Dustin Ruoff produce. From Aug 5, 2022. Blue Origin rocket developments seem to have been in development for decades. They've only just got their sub-orbital New Shepard rocket launching and, even now, they aren't launching that often. Their orbital New Glenn rocket keeps getting delayed and might even be obsolete to SpaceX rockets if it ever delivers. With Elon Musk's SpaceX leading the way in commercial spaceflight and Branson's Virgin Galactic offering an alternative, has Jeff Bezos merely spent a lot of money on Blue Origin that he won't be able to recover?

Cheap Astronomy - Fantastic Physics Formulas, Episode 10
Blowing off some steam. Read by Barry Haworth and Duranee, written by Steve Nerlich, with technical advice from Stephen D'Souza. - The orbit equation: There are several orbit equations around, but this orbit equation tells you what orbital velocity you need to maintain an orbit at a particular altitude. - Entropy and the Inequality of Clausius: Getting to this formula requires a bit of a story, but it’s worth it as it ends up explaining which direction the Universe is moving in. The conversion of heat, a form of energy, into work dates back to ancient Roman times, although heat engines built to do proper industrial work first appeared around the start of the 17th century, mostly steam engines that first pumped water out coal mines and then later drove locomotives, as well as driving a range of other piston-driven machines.

Exoplanet Radio - Ep. 22: HAT-P-67b: The Largest Known Exoplanet
From August 17, 2023. According to the NASA exoplanet archive, HAT-P-67 b holds the distinction of being the largest exoplanet in terms of size. With exoplanet classification, one always needs to be careful - especially when it comes to size and mass - because there is a fuzzy boundary with large planets where if they become too large, they are considered a brown dwarf star. This is a body that almost made it to star status but doesn’t have enough mass or material for nuclear fusion to take place.

Travelers in the Night Eps. 739 & 740: Comet Groeller & Asteroid Billiards
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 Feb 13 & March 22, 2019. Today's 2 topics: - My Catalina Sky Survey teammate Hannes Groeller was asteroid hunting with our Schmidt telescope on Mt. Bigelow, Arizona when he discovered his first comet: P/2019 B2 (Groeller). After the Sun bakes out all of the frozen gasses, Hannes's Comet, will lose its coma and tail and become indistinguishable from one of the millions of main belt asteroids orbiting the Sun between Mars and Jupiter. - NASA's Double Asteroid Redirection Test or DART for short will test methods to make a dangerous asteroid miss Earth.

UNAWE - A Missing Ingredient
From September 10, 2020. The Universe is full of unanswered questions. And more than a few unquestioned answers! One of the biggest questions astronomers are trying to answer is what is the Universe made of? OK, sure, we know about protons, neutrons & electrons already. But astronomers also know that the Universe is full of dark matter, but we still don’t fully understand it…Dark matter is a mysterious and peculiar material that got its name because it doesn’t give off any light - it’s totally invisible at wavelengths our eyes can see. Dark matter remains as elusive as Alice in Wonderland's Cheshire Cat. You can only see its grin (in the form of gravity) but not the animal itself. Yet, astronomers think there’s 5 times as much of this strange material in the Universe as there is normal matter that we can see.

EVSN - Cosmic Billiards Leads to Inner Planetary Growth
From September 28, 2021. The inner solar system was a wild and wooly place as the planets were forming, and new research shows that the collisions that formed Earth and Venus were likely of the hit-and-run variety. Plus, polar ice loss warps the planet, and a black hole eats a star. We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

Actual Astronomy - Stars: A Month by Month Tour of the Constellations with Mike Lynch
Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. Mike Lynch grew up in Richfied, Minnesota. After two years at the University of Minnesota in the Twin Cities he transferred to the University of Wisconsin in Madison and earned his B.S. degree in Meteorology. Shortly after he was hired as a broadcast meteorologist at WCCO Radio in Minneapolis and has been there for over 30 years. Mike has covered all kinds of weather from deadly tornados to record cold snaps. In fact on February 2nd, 1996, he broadcasted from Tower, Minnesota when the temperature dropped down to 60 below zero, an all time record low for the state of Minnesota. Mike’s other passion has been astronomy. He built his first telescope when he was 15 and for over 40 years has been teaching classes and putting on star parties through community education, nature centres, and other organisations throughout Minnesota and Wisconsin. His goal is to help people make the stars their old friends. From 2004 to 2007 Mike wrote Astronomy/Stargazing books and WCCO Minnesota Weather Watch in 2007 and writes a weekly Starwatch column for the St. Paul Pioneer Press and more than two dozen other newspapers across the United States. His most recent book is “Stars: A Month-by-Month Tour of the Constellations!” We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

Travelers in the Night Eps. 281E & 282E: Close Passes & Tilted History
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. Today's 2 topics: - During a recent 3 night observing run my Catalina Sky Survey teammate Rose Matheny discovered 4 asteroids which can come to less than one half the Moon's distance from us. Interestingly one of them passed about 25,000 miles over the South Pole 2 days after Rose discovered it. Rose's four close approaching asteroids are small ranging in size from 15 to 60 feet in diameter. None of them are big enough to reach the Earth's surface and make a crater. However, the largest is about the size of the one whose air blast shock wave injured nearly 1500 people when it exploded over Chelyabinsk, Russia in 2013 . - Seasons are created by the fact that the Earth's axis of rotation is currently tilted 23 1/2 degrees relative to our path around the Sun. The slight out of roundness of the Earth's orbit combined with a 41,000 year cycle in its 3 degree axis of rotation wobble can cause the Earth's climate to change on very long time scales. Turns out that these astronomical cycles are likely to be the drivers of where you are from and where you live.

Cheap Astronomy - Dear CA # 106: Articles On Particles
Very Small Rocks. Particular rocks… Dear Cheap Astronomy – What’s a particle? Probably the best answer is that particles are those things detected by particle detectors. Unfortunately this can range from dust detected by atmospheric particle detectors to those things detected within the large hadron collider – which are a special category of those things that particle accelerators accelerate and particle colliders collide. Dear Cheap Astronomy – What sort of Astronomy is done on the ISS Conducting astronomy from a moving platform has it challenges. Of course the Earth itself is a moving platform, both rotating on its axis and also orbiting the Sun – but those motions are relatively slow. You can set a cheap backyard telescope, like our own Sky Station 1, still- operational after all these years, and keep observing Saturn – just shifting the scope every now and again to keep it in view.

The Last Minute Astronomer - July Episode
Hosted by Rob Webb. July’s fireworks include Saturn coming back around closer to being an evening planet, Mercury and Venus dancing low in the evenings, and some magic between the Moon and Spica. 1st - Waning Crescent Moon is just above Mars in the AM 3rd - Up and to the left of Jupiter in the AM 6th - Above Venus, to the left of Mercury, NNW just after sunset 7th - Above Mercury, NNW just after sunset 24th - To the right of Saturn, after 11pm, waning gibbous 25th - To the left of Saturn, after 11pm, waning gibbous 30th - Above Mars and Jupiter, ENE after 2am, waning crescent 31st - Left of Jupiter, ENE after 2am, waning crescent July 13th – Lunar Occultation of Spica – Not so common to be able to see a star stop shining and then start back up again…sort of. Check for timings for your area, but the gist is that North and Central America, particularly on the Eastern side, will be able to watch Spica wink out as the dark side of the Moon crosses in front of it. As an example, if you live near Harrisburg, PA, look WSW for the Moon after 11pm. Right around 11:24pm Spica will disappear. Unfortunately, this happens only about 10° above the horizon, leaving the reappearance invisible to us. Reappearance will be visible before the Moon hits the horizon if you live approximately west of the Mississippi. Music was produced by Deep Sky Dude and used with permission.

Travelers in the Night Eps. 735 & 736: One Thousand & Home Wrecker
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 Mar 10 & 17, 2023. Today's 2 topics: - For the first time in history, an asteroid hunting team, the Catalina Sky Survey, has discovered more than 1,000 Earth approaching asteroids in a single year. They are an interesting part of our environment. - The extremely remote chance that a dangerous mountain sized space rock has our number on it is what keeps my team going to our four telescopes in the Catalina Mountains north of Tucson, Arizona.

Ralph Wilkins hosts. Damien Phillips, John Wildridge and Dustin Ruoff produce. From Aug 12, 2022. The International Space Station has been continuously inhabited for more than 20 years but its end is coming. - But how do you bring down a spacecraft the size of a football field? - How do you squeeze maximum use out of the orbiting laboratory while it's still up there? - What are Space companies like Axiom, Blue Origin and SpaceX planning in this arena of commercial spaceflight? - What will happen to the falling space debris? The thumbnail for this video may look like internet sensationalism, but this is the fate of the ISS!

H’ad Astra Historia - ‘A Distinguished Career’ Part 2

H’ad Astra Historia - ‘A Distinguished Career’ Part 2
Hosted by Loretta Cannon. Today’s guest: Dr. Steve Maran (retired from NASA and AAS ) shares stories with us from his almost 70 years working, and having fun, in astronomy. 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. Podcast music: "Frost Waltz" Kevin MacLeod (incompetech.com), licensed under creative commons: by attribution 4.0 license () Bio: Loretta Cannon, an AAS affiliate via Rose City Astronomers, is a member of the leadership committee for the Historical Astronomy Division (2023-2025). She is a polymath with degrees in anthropology, microbiology & biochemistry, and has many years of experience in both the private sector and government. When not reading some of her way-too-many books, she watches BritBox, creates recipes, or plays in the garden. She chose science writing/editing in astronomy as a new career. In short, she’s a science-and-word-nerd-foodie-with-a-plant-habit who really likes the stars.
