Cheap Astronomy - Dear CA Ep. 132: Mining Again
The 365 Days of Astronomy
Hosted by Steve Nerlich. Bringing it home. Cheap Astronomy digs in to asteroid mining. Dear Cheap Astronomy – Are rubble pile asteroids easier to mine? Rubble pile asteroids are a collection of rocks that have accreted together under their mutual gravity, but the object they form isn’t massive enough for gravity to compress it into one unified object. Instead, the rocks that gather together remain as individual rocks. So, from a mining perspective there’s an advantage in that you can just pick up those individual rocks without needing drilling or explosives. Dear Cheap...

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.

The International Astronomical Union and WNYC’s award-winning science podcast, Radiolab, invite people worldwide to take the unique opportunity to suggest a name for one of Earth's quasi-moons, 2004 GU9. Submissions are open until 30 September and the winning name will receive official recognition by the IAU.
https://radiolab.org/moon-official-rules/
For millennia, people across the globe have built deep connections to objects in the night sky, assigning them names and stories imbued with their cultural heritage and understanding of the world. Naming campaigns highlight these connections and provide the global public with a chance to have their creativity embedded in the cosmos.
Earlier this year, Latif Nasser, co-host of the science podcast Radiolab ( https://radiolab.org ), petitioned the International Astronomical Union (IAU) to name a quasi-moon of Venus after noticing a typo on a map of the Solar System. The saga was documented on a Radiolab episode and tweet thread from Nasser that went viral, opening the door for listeners to learn more about this fascinating class of objects. The episode established a connection between the IAU and Radiolab, which is produced by WNYC Studios [1]. The organisations have now teamed up to invite a global audience to engage with this field of astronomy through a new naming contest for one of Earth’s quasi-moons.
Quasi-moons of a planet are asteroids that orbit the Sun and follow a path similar to that of the planet. Due to the relative motion of the two objects, it appears as though the asteroid is orbiting the planet from the perspective of an observer on the planet’s surface. If a quasi-moon is near the Earth, it might seem as if we have a new moon, even though it is hardly affected by the Earth's gravitational pull.
By taking part in “Name a Quasi-Moon!”, people worldwide will have the chance to leave their mark on our sky with official recognition from the world’s authority responsible for assigning names to objects in our Solar System and beyond. By involving the IAU’s wide international network, the collaboration will reach new audiences, ensuring our sky will be more representative of the world’s diverse ideas, cultures, perspectives, and ways of knowing.
