About this episode

The episode discusses the discovery of a superkilonova and recaps the Artemis II mission, highlighting its successes and challenges.

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!
