Supernovae and Gamma Ray Bursts are expected to wipe out any complex life in the neighborhood. Today’s paper looks at how common these events are in different galaxies over time.
Galactic bars channel gas into the central regions of spiral galaxies to birth new stars. Are they also responsible for lighting up the black holes?

In a strange, half-lost, piece of work Roger Penrose draws four figures dropping their lines into the depths of a black hole, and in doing so finds a new and hugely influential way to steal energy away from the heart of a spinning singularity.
Can we detect the signature of an AGN reionization?
When it comes to habitability for Earth-like life, we’ve got more than just liquid water to worry about. Today’s astrobite looks at how planets could lose portions of their atmospheres to quasar radiation.
Today’s paper discusses a new way to measure physical properties of galaxies—including, for the first time, “star formation acceleration.”
