Hot Takes on Water on Earth and Black Hole Singularities

We're all about the weather on this episode, with a new study showing that even relatively distant supernova may have affected the Earth's climate in the recent past. And the James Webb Space Telescope has observed exoplanet WASP-107b to have clouds of sand vapor. Plus, we have two hot takes and two Top astroquarks!

Original top quark Tracy Becker is back to bring us up to speed Europa Clipper's flyby of Mars, and we learn about a new way for planetary cores to form without so much heat. Join us for all this, plus lava fountain trivia, space news, and much more.

A major update to the predicted end of the universe has it coming much earlier than previously anticipated. However, we still have plenty of time to get our affairs in order, and the update has to do with spaghettification, and anything with spaghettification can't be all bad. We also talk about active asteroids, your ideal night sky, and cosmological trivia. 

We get lucky and catch a rogue supermassive black hole in the act of slurping up a star as it meanders through a distant galaxy. Closer to home, the detection of a second trinary, or triple, system in the Kuiper Belt beyond the orbit of Neptune bolsters the streaming instability theory of planet formation. We talk about all that and what it has to do with the Tour de France, as well as space news and trivia.

The asteroid Vesta may be a fragment of a much larger protoplanet, and astronomers examine old data to discover a large molecular cloud lurking right in the solar system's backyard. Get all the details, plus habitable exoplanets get another look, space news, and trivial matters with your friendly neighborhood astroquarks.

NASA's Lucy mission had a picture perfect encounter with the asteroid Donaldjohanson on its way to the first ever flybys of Trojan asteroids. Discoveries of ancient supermassive black holes challenge theories of their formation. If dark matter is composed of ultralight particles (lighter than a neutrino), that could resolve the mystery. Join us for these and other cosmic discoveries, space news, trivia, and more.

The astroquarks discover hot takes and explore the nature of ice, the origin of Earth's water, and the trouble with the singularities at the hearts of black holes. Plus, we have a stumper, astronomical trivia, and much more. 

Venus's extra-thick crust may be extra chewy, allowing convection to occur and helping power volcanoes into the current era. New observations of the distant universe, meanwhile, show that dark energy may not have behaved as expected in the standard cosmological model. We'll break it all down for you together with space news and trivia with your friendly neighborhood astroquarks.

A survey of nearby stars establishes the rate of supernovas in our general neighborhood. Evidence indicates we had nearby stellar explosions at the times of two mass extinctions. Those supernovas may have decimated the ozone layer and contributed to extinctions and climate changes. Plus, we recorded on April 1 and take a look at silly April 1 science papers, and we get tilted with our trivia and space news. Join us, won't you?

If there are Hycean worlds and if they have a certain kind of microbial life and if there is enough of it, JWST might be able to see the chemical products of that in the planet's atmosphere. We take a look at that, debris from neighboring stars entering our solar system, and the first results from the Euclid space telescope. Join us for all this plus a hilarious double stumper and more.
