Our Galaxy’s Supermassive Black Hole May Have Had a Companion in the Past
Could there have been two massive black holes in our galaxy’s center at one time? New modeling of fast-moving stars in the Milky Way’s halo suggests the answer is yes.
Recent simulations tackle the question of how dense star clusters like those spotted by JWST formed in the early universe.

An exploration of galaxies during our universe’s star-formation heyday reveals a population of bright, compact regions called green seeds.
What happens when a young star captures some extra gas and dust? New observations of a dusty disk reveals how a late-stage infall event may be influencing planet formation in AB Aurigae.
Gravitational-wave detectors have spotted dozens of merging black hole pairs. New research explores whether any of these collisions could have happened in the disk around an accreting supermassive black hole.
Astrobites reports on a study that shows that hot stars seem to host fewer small planets than their cooler stellar cousins.
What has the supermassive black hole at the center of the Milky Way’s galactic neighbor been up to? The Chandra X-ray Observatory provides all the details.
