Basin Instinct - Cosmological Structure and Edible Asteroids

New observations contradict earlier studies about the possibility of another belt of comets orbiting the Sun twice as far away as Pluto. We'll take a look at what's what in the outer solar system and also explore whether black holes may help explain the Hubble tension. We also play FLOD (Flyby, Land, Orbit, Destroy) and have some "how many planets" trivia.

Join Strange and Down quarks for a close look at Trojan asteroids, the forgotten asteroids of the solar system. NASA's Lucy mission is en route to take our first close look at these denizens of the outer solar system and has an Earth gravity assist in December 2024. As you'll see in our trivia, the numbers of Trojans may surprise you. Jupiter is the king of the Trojans, but we'll take a closer look at the first comfirmed Trojan of Saturn.

We get a tour of our place in the grand cosmological scheme of things with new mapping of the local Basin of Attraction. Spoiler: also Jim's new stage name. And we explore the final frontier of In Situ Resource Utilization with studies of how to get edible nutrients from the raw materials in asteroids. It's a little bit gross. Plus space news, trivia, and more. Join us to learn about all this (and all of our new stage names).

Original Top Quark Dr. Tracy Becker returns to her old stomping grounds to hang with the Walkabout crew and send Europa Clipper on its way to Jupiter. Join us for a preview of this mission's ambitious goals and the exciting journey it took to the launch pad. Also, new research suggests the Earth may escape a fiery death when the Sun becomes a red giant. We have, of course, space news, space history trivia, and much more. 

We’ve got mini black holes as potential dark matter candidates and monstrous black holes spewing jets to cosmological scales. Who better than Top quark Jim Cooney to take us through these black holes? No one, that’s who. We take a deep dive into meteorites, particularly those that have come from Mars. You may be surprised to learn how many we have, and now we know more about where those free Mars samples originated from on the red planet. Join us for all this, space news, and trivia.

Gravitational waves may provide a new way to observe supernovae in our own Milky Way galaxy and determine when they produce black holes and when they result merely in neutron stars. Closer to home, scientists did some clever detective work to figure out the source of a mysterious 9-day seismic shaking here on Earth. The culprit: a giant, regular sloshing in a fjord triggered by a landslide as a result of warming temperatures and melting land ice. Join us for this and other astro news including an interesting mini-moon and funny science lingo.

Tiny samples brought back from the Moon hint at surprisingly recent volcanic activity. What's up with that?! Elsewhere in the galaxy, a detailed study of over 100,000 stars identifies the metallicity cliff. This is where stellar composition that is low in heavy elements seems to inhibit the formation of at least some types of exoplanets. The astroquarks have all the details for you, as well as a Polaris Dawn update and nerd trivia. Join us, won't you?

The Astroquarks are joined by former NASA astronaut, PhD Chemist, and retired USAF Colonel Cady Coleman at Dragon Con 2024 for a wide ranging discussion of space flight, institutional challenges, training, flute playing, and more. 

Recent (astronomically speaking, of course!) perturbations to Mimas's orbit may be the explanation for the surprising presence of a global subsurface ocean in this tiny moon of Saturn. Meanwhile, the European Space Agency's JUICE (Jupiter Icy Moon Explorer) mission successfully completed a novel gravity assist making use of the Earth's Moon and the Earth to send it towards... Venus! We have all the explanations, space travel stumpers, trivia and more.

New research shows that the asteroid that killed the dinosaurs some 66 million years ago formed in the colder, more distant reaches of the solar system. The Astroquarks have taken it upon themselves to dub this asteroid Barney. We’ll update you on that new research and a surprising discovery from Mars Insight data that suggests Mars has a potentially huge amount of delicious H2O not to far beneath its surface. It’s just a bit dirty, is all. And we have lots of space news, stumpers, and more. Join us, won’t you?
