  • Why Is There A Universe At All?
    Things would be a lot simpler and a lot less interesting if charge parity existed in the universe, but there would be no one to appreciate that simplicity because we would not exist! New results from the Large Hadron Collider provide a hint at explaining why there is matter in the universe and it was not all eliminated in a dramatic annihilation of matter-antimatter collisions. So, that's a relief! And we have space news, meta-trivia, solar system news and more. Join us, won't you?

  • The Amazing and Crazy Story of Gemini and Jumbo Black Holes
    The astroquarks are joined by Jeffrey Kluger, editor at large at Time Magazine and author of 13 books including Apollo 13 and the new book on the Gemini program. Tune in to hear about some of the outlandish ideas that were explored on the way to the Moon. Plus, top quark gives us a look at a new class of black holes that we've decided are "Jumbo Black Holes". All that plus twin trivia, a hot take, and more.

  • Rings Around a Comet, Betelbuddy, and Odd Jupiter Moons
    These rings aren't around Uranus, they're somewhere even more odd. We discuss the mysterious and changing ring system around the Centaur object Chiron, new clues about the origin of the solar system from the irregular moons of Jupiter, and the puzzling stellar companion to Betelgeuse. Plus, top quark Jim Cooney stumps us with trivia.

  • Adaptive LIGO and a New Look at an Old Crater
    Adaptive optics techniques get applied to the mirrors in the LIGO gravitational wave observatory, promising a five-fold or greater improvement in sensitivity to gravitational waves from colliding black holes across the universe. And right here in our backyard, a suspicious sub-surface crater-like feature gets a new look that appears to confirm its extraterrestrial origin. Join us for space news, trivia, and more.

  • Einstein Cross Reveals Dark Matter and a Life-y Mars Rock
    We take a look the Cheyava Falls rock on Mars, or rather the Perseverance rover took a look at it, and we discuss what it saw which were some intriguing mineral formations that could have a biological origin. And gravitational lensing has enabled astronomers to map the distribution of dark matter in a small cluster of galaxies, providing a new tool to understand the distribution of this mysterious stuff. Join us for these stories, space news, space trivia, and a fake sponsor!
