  • Whacky Black Hole Collisions and Strange Uranian Rings
    May 20 2026

    Mysterious bright blue flashes from relatively empty parts of the universe have a new possible explanation involving, what else, black holes. We explore this new idea to explain Luminous Fast Blue Optical Transients (LFBOTs) with black hole collisions, take a peek at the black hole in our own Milky Way, and discuss some puzzling observations of two of the rings of Uranus. Plus, we have a stupid stumper, exoplanet trivia, space news, and a top quark hot take!

  • Little Plutino Has An Atmosphere and Making Sense of Saturn
    May 13 2026

    A Plutino, an object that shares Pluto's orbit but which is much smaller than Pluto, appears to have a very thin global atmosphere. We discuss the detection and how such a small body could hold onto even a thin atmosphere, as well as a new model that describes many of Saturn's peculiarities with a recent collision between its big moon Titan and a precursor to the sponge-y moon Hyperion. Join us for all this, space news, astronomy trivia, and much more.

  • Superkilonova and Artemis II Recap
    Apr 28 2026

    Gravitational waves and light combine to reveal what is suspected to be a superkilonova which is much cooler than the name suggests. Cool in the cool way, not the temperature way. Learn about splitting neutron stars and, in our Artemis II recap, we revisit the highs (awesome mission, great astronauts) and lows (broken space toilet) of the mission that took people a record distance from the Earth, and what's next. Plus, trivia, stumper, fake sponsor, and all the nuttiness you've come to love and miss from the astroquarks. We're back!
