200 million years after two galaxies began to merge and created one of the most powerful AGN outbursts ever observed, they left behind an arc of star formation resembling beads on a string.
Pair-Instability Supernovae could be the fate of some of the universe’s most massive stars. Today’s Astrobite explores if dark matter accumulated in the cores of these stars could help drive these gargantuan explosions!
Today’s paper finds a new hungry supermassive black hole, fresh out of hibernation!
Black holes are hungry, loud eaters! Find out what they sound like as they burp the remains of a star!
