Astronomy Cast Ep. 787: Evolved Stars (They're not dead yet!)
The 365 Days of Astronomy
Hosted by: Fraser Cain ( ) and Dr. Pamela L. Gay ( ) Streamed live on Mar 16, 2026. Main sequence stars spend most of their time being… normal. Fusing hydrogen into helium in their cores. Producing radiation. But as their stockpiles of hydrogen run out they switch to other fuels, starting to climb the ladder of the periodic table of elements. And this is when things get weird. As we get more and more observations of the cosmos, our understanding gets more detailed. In this episode we look at all the ways a star can die and the updates that we've learned in the past 20 years of Astronomy...

Travelers in the Night Eps. 865 & 866: New Potentially Hazardous Asteroid & Interstellar Visitor
The 365 Days of Astronomy
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 September 2025. Today's 2 topics: - On a short June night my Catalina Sky Survey teammate Greg Leonard was observing with our 60 inch telescope on Mt. Lemmon, Arizona in the constellation of Ursa Major when a relatively bright fast moving point of light appeared in a set of his images. Even though on its current path Greg's discovery, 2025 MM89, has virtually no chance of impacting our home planet asteroid hunters will...

Cheap Astronomy - Dear CA 131: What’s The Point?
The 365 Days of Astronomy
Hosted by Steve Nerlich. Cheap Astronomy asks what's the point and then gets some sunshine. Dear Cheap Astronomy – Did the Universe start from a single point? This hypothetical concept is commonly stated in pop science blogs and we are guilty of doing the same here at Cheap Astronomy. However, it’s not necessarily correct. As with most things relating to the Universe, all we can really talk about is the observable Universe. All evidence available does suggest that it emerged from a point source 13.8 billion years ago, but if the actual Universe is bigger than the observable Universe –...

Ask A Spaceman Ep. 268: What are Little Red Dots?
The 365 Days of Astronomy
Hosted by Dr. Paul M. Sutter. What do we find when we push the James Webb Space Telescope to its limits? Are Little Red Dots newborn galaxies or old black holes? What are they teaching us about the early Universe? 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. 786: Wolf-Rayet Stars
The 365 Days of Astronomy
Hosted by: Fraser Cain () and Dr. Pamela L. Gay () Streamed live on Mar 9, 2026. You think the Sun is a terrifying ball of fire and fury? Wait until you learn about today’s topic: Wolf-Rayet stars! These are massive, dying stars hurling their outer layers out into space before detonating as supernovae. Big stars live brief lives, and Wolf-Rayet stars are the punctuation mark we see before things go supernova.

Travelers in the Night Eps. 863 & 864: Space Elevator & Lunar Debris
The 365 Days of Astronomy
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 2025. Today's 2 topics: - In a recent study Dr. Lynnane George and her co-authors investigate Space Elevator technology to remove materials from Ceres and deliver them to orbital depots around the solar system. The tiny gravity of Ceres, nano-fiber technology, and different water propulsion systems are utilized by Dr. George and her team to construct theoretically possible systems which would extract raw...

NOIRLab - Results From Six Years of the Dark Energy Survey
The 365 Days of Astronomy
The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the Universe using the U.S. Department of Energy-fabricated Dark Energy Camera, mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at CTIO, a Program of NSF NOIRLab. Their completed analysis combines all six years of data for the first time and yields constraints on the Universe's expansion history that are twice as tight as past analyses. In this podcast, Dr. Yuanyuan Zhang discusses the Dark Energy Survey results and how they inform the next steps in dark...
