Recent Lunar Volcanic Activity and the Metallicity Cliff

from Walkabout the Galaxy · host Josh Colwell, Addie Dove, Audrey Martin

Tiny samples brought back from the Moon hint at surprisingly recent volcanic activity. What's up with that?! Elsewhere in the galaxy, a detailed study of over 100,000 stars identifies the metallicity cliff. This is where stellar composition that is low in heavy elements seems to inhibit the formation of at least some types of exoplanets. The astroquarks have all the details for you, as well as a Polaris Dawn update and nerd trivia. Join us, won't you?
