Astrobites reports on what might be powering the strange, puzzling young galaxies known as little red dots.
Confirmed at Last: Barnard’s Star Hosts Four Tiny Planets
Following decades of disproven claims, four small exoplanets have been confirmed to orbit Barnard’s Star, the second-closest star system to Earth after Alpha Centauri.
Astronomers Measure Turnover in Initial Mass Function for the First Time
When a gas cloud collapses to form a star cluster, how many objects form, and what are their masses? Research published today provides answers about the low-mass end of the star and brown dwarf formation process.
Observational Obstacles to Detecting Early Universe Supermassive Black Holes
Recent JWST observations have stirred up concerns about over-massive black holes in the early universe. A new study allays these concerns while showing that over-massive black holes are just scratching the surface of the full black hole population.
