Vesta Chip Off the Old Block and a Nearby Dark Molecular Cloud
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.

Ultralight Dark Matter and Peanut Asteroid Hot Take
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.

Hot Takes on Water on Earth and Black Hole Singularities
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.

Weird Convection on Venus and a Wrinkle in the Lambda Cold Dark Matter Model
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.

Supernovas and Mass Extinctions
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?
