18:21In a difficult week for Los Angeles, we hope this episode can provide a little bit of respite. Jessica Shaw is joined by Keely Flaherty from Tudum for a deeper dive into the gripping limited series, American Primeval , starring Betty Gilpin and Taylor Kitsch. Then also talk about the delightful return of Cameron Diaz and Jamie Foxx in the new action comedy, Back in Action , directed by Seth Gordon.

46:03Pluto and its largest moon, Charon, orbit each other with gazes lovingly fixed on each other, held in place by a romantic tidal attraction. But Charon's large size has always been difficult to explain. New simulations show that their love affair may have started at the beginning with a "Kiss and Capture" collision, much gentler than the devasting impact that formed our own Moon. Hear all about that, Centaurs, space news, space trivia, and a new way to explain away Dark Energy with your friendly neighborhood astroquarks.…

45:25We kick off 2025 with oddities from quasi particles, to cosmic rays, to the moons of Pluto. What has mass when it moves in one direction and doesn't when it moves in another direction? How do thunderstorms on Earth interact with cosmic rays? What is up with Pluto's moons? Join us as we tackle these questions as well as the stumper and special top quark trivia. It's all part of the package in an episode of Walkabout the Galaxy.…
We know about extinct comets and active asteroids, but now we've got something in between: dark comets, whose orbits indicate cometary activity, but we can't see it! We'll get the scoop on these interesting objects, a flare from a supermassive black hole, and a twist on the question of the age of Saturn's rings. Plus, we have our end-of-the-year rocket launch roundup, and a special astrophysical FLOD stumper for top quark Jim Cooney.…
Top quark Jim Cooney explains why making big blobs is hard and how new observations are helping us understand how the universe made big immensely big blobs more commonly known as giant elliptical galaxies. Nature loves to make a disk, and we love to tell you all about the cool things nature does, including a solid state greenhouse on ancient Mars that may have produced a huge buried supply of water to create giant rivers near its south pole. Join us for this and more mind-blowing stuff. It's all part of our Walkabout the Galaxy.…

43:44It's a good news bad news story with the detection of the neutrino fog. This signal from solar neutrinos may confound our search for certain dark matter candidates, but at least we know our detectors are very, very sensitive! We also take a look at magnetic fields in the outer solar system, specifically why Uranus's magnetosphere was so weird when we visited in 1986, and what tiny grains from a near Earth asteroid may be telling us about the magnetic field four and a half billion years ago. Join us for all that, and of course space news and stupid trivia.…

41:34If you're speaking English, not Latin, do you really have to say "supernovae" instead of "supernovas"? Also, they are, in some sense, created equally: explosion of a white dwarf, but the outcomes are not all equal. You are welcome for this grammatical tangent, and please enjoy our fun discussion about weird tesserae (more Latin!) on Venus and the whole standard candle story of type 1a supernovae gets a rewrite. On this episode of Walkabout the Galaxy, you can also enjoy solar energy/spacecraft trivia, space news, and general hilarity at no extra charge.…
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.…

45:09We 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.…

41:03Gravitational 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.…

46:01Tiny 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.
