For the first time, researchers using pulsar timing arrays have found evidence for the long-sought-after gravitational wave background. This discovery opens a new window onto supermassive black hole binaries and, potentially, entirely new physics.
Recently, a young brown dwarf got the full JWST treatment. Analysis of the data both confirms known trends and hints at new discoveries.
Astrobites reports on a galaxy cluster that may have taken only 5 billion years to “relax,” doing so faster than previously thought possible.
