Black Hole Spindown Chirp and a 9-Day Geologic Rumble

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

Gravitational waves may provide a new way to observe supernovae in our own Milky Way galaxy and determine when they produce black holes and when they result merely in neutron stars. Closer to home, scientists did some clever detective work to figure out the source of a mysterious 9-day seismic shaking here on Earth. The culprit: a giant, regular sloshing in a fjord triggered by a landslide as a result of warming temperatures and melting land ice. Join us for this and other astro news including an interesting mini-moon and funny science lingo.
