About this episode

The episode discusses the impact of supermassive black holes on neighboring galaxies and features research on L type asteroids.

Supermassive black holes can be terrible neighbors. New research shows that their powerful jets of charged particles can shut down star formation in neighboring galaxies within the galaxy cluster, which is just plain rude. Closer to home, our own Down Quark Audrey Martin is part of a study shedding new light (with the James Webb Space Telescope) on the mysterious L type asteroids, that formed at very high temperatures early in our solar system's history.
