Ask A Spaceman Ep. 266: Is the Universe Made of Math?
The 365 Days of Astronomy
Hosted by Dr. Paul M. Sutter. Why is math so effective at describing the Universe? What is reality is made of math? What does it mean for us to be conscious beings in a mathematical structure? I discuss these questions and more in today’s Ask a Spaceman! Support the show: All episodes: Watch on YouTube: Read a book: Keep those questions about space, science, astronomy, astrophysics, physics, and cosmology coming to #AskASpaceman for COMPLETE KNOWLEDGE OF TIME AND SPACE!

Astronomy Cast Ep. 782: Luminous Fast Blue Optical Transients
The 365 Days of Astronomy
Hosted by: Fraser Cain () and Dr. Pamela L. Gay () Streamed live on Feb 13, 2026. Modern astronomy has found that the Universe can surprise us. Here’s one which astronomers have called Luminous Fast Blue Optical Transients. They’re kinda like supernovas, they’re kind of like gamma ray bursts, but they’re not like them. So what are they? In the distant Universe, are blue light flashes, bright and hard to understand. These objects, uncreatively named "Luminous Fast Blue Optical Transients," are just the kind of puzzle astronomers love. In this episode, we look at their discovery and our...

NOIRLab - Mysterious Metallic Cloud Discovered Orbiting Mystery Object
The 365 Days of Astronomy
Sweeping winds of vaporized metals have been found in a massive cloud that dimmed the light of a star for nearly nine months. This discovery, made with the Gemini South telescope in Chile offers a rare glimpse into the chaotic and dynamic processes still shaping planetary systems long after their formation. In this podcast, Dr. Nadia Zakamska describes the discovery of this object, stemming from a mysterious dimming of a star, to the analysis of the gas cloud. Bios: - Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona. - Dr. Nadia...

EVSN - Galaxy Mergers Trigger Black Hole Growth
The 365 Days of Astronomy
From May 21, 2020. Join us today as we discuss the impressive work by an undergraduate student who figured out how galaxy mergers influence the growth of supermassive black holes. We talk about a gigantic galaxy found in the early universe. And finally, we look at amazing images of a planet being formed around a distant star.

Guide To Space - What Did Cassini Teach Us? Remembering Cassini and Saying Goodbye
The 365 Days of Astronomy
From March 8, 2017. In just a few months, NASA's Cassini spacecraft is going to die, crashing into the planet Saturn. Let's look back across the mission's history. What were the highlights? What did we learn? Team: Fraser Cain - @fcain / frasercain@gmail.com Karla Thompson - @karlaii Chad Weber - weber.chad@gmail.com Ask me my favorite object in the Solar System, especially to see through a telescope, and my answer is always the same: Saturn. Saturn is this crazy, ringed world, different than any other place we’ve ever seen. And in a small telescope, you can really see the...

Cheap Astronomy - Dear CA Ep. 129: More Rocks
The 365 Days of Astronomy
A podcast about rocks, big and small. Dear Cheap Astronomy – What’s Psyche really like? Psyche is an asteroid in the asteroid belt and apparently a very metal rich one, which makes it a prospecting target for budding asteroid miners. Pysche is also a spacecraft, launched on October 13, 2023. We’re recording this episode about one month after launch when it’s already over 15 million km from Earth – and its destination? Yep, Psyche – the asteroid. Dear Cheap Astronomy – How is Mars Sample Return mission going? Here at Cheap Astronomy we’ve often said that landing on Mars...

Deep Astronomy - Discoveries of Webb Space Telescope Ep 3: The Flares of Sagittarius A*, Our Galaxy's Black Hole
The 365 Days of Astronomy
From April 14, 2025. Astronomers using the JWST have made direct observations of the black hole at the center of our galaxy: Sagittarius A*. These observations are possible because the Webb Space Telescope can peer through the dust at the center of our galaxy using infrared light. These observations surprised astronomers.

Astronomy Cast Ep. 781: Awakening Black Holes
The 365 Days of Astronomy
Hosted by: Fraser Cain () and Dr. Pamela L. Gay () Streamed live on Feb 2, 2026. One long standing mystery in astronomy were the quasars. Incomprehensible energy blasting out of a point-like source, billions of light years away. We now know these are actively feeding supermassive black holes, which can turn off and on in a startlingly short period of time. Today: When black holes awaken! Our Universe is filled with sleeping monsters. And sometimes, whether we want it or not, they wake up hungry. In this episode, we take a look at the science behind how and why black holes of all sizes can go...

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 June, 2025. Today's 2 topics: - In the search for life on Mars, Europa, Titan, and elsewhere in the universe astro-biologists are scouring the Earth for creatures tough enough to flourish under really difficult conditions. So far the leading species are the Tardigrades commonly known as water bears or moss piglets. - Data are consistent with the hypothesis that the planet K2-18b is a Hycean planet with a warm liquid...
