Pluto Cryovolcano and a Cosmological Supervoid

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

At Pluto's frigid temperatures, even what we breathe is frozen. This can give rise to unusual cryovolcanism, and new research suggests a super cryovolcano tens of kilometers across on the ninth planet (yes, we went there). Speaking of super things, we also review the argument that we are located in a cosmological supervoid and whether than can explain some of the mysteries surround the Hubble constant. Join us for all that, space news, trivia and more.
