Quasars, those incredibly bright and distant sources powered by supermassive black holes, may have a trick to their radiation that let's us use them as standard candles. We'll dive into that and take a dive in close to the Sun with the Parker Solar Probe to learn about its discoveries of new populations of dust in the inner solar system. Plus, impactor trivia, and how long would you want to stay in space?

Light's odd way of behaving both like a particle and a wave is nothing new, but a cool new experiment shows that it's not an either/or but a continuum of gradations from wave to particle. The universe has some crazy stuff going on. We use the wave nature to take a look at an odd transient phenomenon at the core of the Milky Way and for Top quark to embarrass Strange quark at trivia.

We explore dwarf galaxies with no star formation and dwarf planets with a clue to a lurking object in the outer solar system. But first Top Quark is stumped by a non-stumper stumper, and our trivia takes us out to the largest structures in the universe. Catch up on all the latest news with the astroquarks, and have fun at the same time.

Will we find extraterrestrial life on Mars, Europa, or an exoplanet like Earth? Or will it be on an entirely different kind of planet, larger than the Earth, smaller than Neptune, and with planet enormous quantities of water? These hydrogen-rich ocean worlds, or hycean worlds, may be habitable. And to keep our own planet habitable, we may need to think about gently nudging asteroids off a collision course rather than blasting them to smithereens.

Saturn's rings are so amazing that they have helped us learn that Saturn's core is a sludgy-soupy beast that doesn't have a sharp boundary. And the waves in the rings are like the Milky Way's spiral arms, one of which has a clump at an odd angle that may be similar to some clumps we see in Saturn's rings! The astroquarks are here to help you fit it all together. Plus, how fast can you walk on the Moon? You might be surprised.

The Galaxy is in turmoil. At the galactic council MEGACON, the forces of Cosplay, Comics, Sci-Fi, Fantasy, Gaming, and more have gathered to restore balance and reason to society. The Astroquarks have lost one of their trio: Top Astroquark. As Charm and Strange struggle to fight the forces of chaos and unreason, the bearded SPACE WHISPERER Brendan Byrne of WMFE arrives on a beam of radio waves to complete the triad and allow the Walkabout the Galaxy to continue… Plus Artemis, Mars, JWST, and Olympic Space Trivia!

It's a tale of pairs and "self-coupling", which causes Top quark endless mirth, in this episode, with Higgs boson pairs, self-annihilating photon pairs producing antimatter (in an electron/positron pair), and a pair of oddly red asteroids. Tune in for another wide ranging episode, also featuring olympic rants.

They have to be out there, and now we have a first direct glimpse of what is likely to be the birthplace of an exomoon - a moon forming in a disk around a planet orbiting another star. We check in on the curious case of FBOTs (fast blue optical transients), and closer to home we've learned that Mars' interior has a bigger core than anticipated. Get this news, space news, trivia linking sci-fi and planetary-sci, and much more.

Lithium is not just in demand for all those new electric car batteries, it seems there's a problem with missing lithium in the universe. We explore the Cosmological Lithium Problem, take a look at what tree rings and the sea floor have to tell us about Earth's space environment, and take a deep dive into wormholes for our trivia.

Beware the Squire of Gothos for the Kepler mission has discovered 4 more new free-floating planets. LIGO has observed the first collision between a black hole and a neutron star, and the ocean of Enceladus just might harbor life. Learn about these astronomical developments and much more, including a Venus exploration trivia and science fiction film rants.
