Researchers measure tiny distortions in the oldest light in the universe to determine where matter is concentrated.

Massive stars are not typically inclined to go gentle into the good night. Some, new work suggests, might dramatically cut themselves in two using a “relativistic blade.”
Three recent studies of the famous red supergiant examine the aftermath of the Great Dimming, probe the possibility of a stellar merger, and reconsider some critical evidence that suggests that Betelgeuse was once two stars.
Astrobites reports on the changing-look active galactic nuclei seen in the first year of the fifth Sloan Digital Sky Survey.
A new interpretation of JWST spectra suggests that exoplanet K2-18b is a gas-rich world without a habitable surface rather than an ocean world.
While collisions between dwarf galaxies usually result in bursts of star formation, new research suggests that galaxy interactions can also make star formation shut off.
New research explores how a star colliding with a disk of gas around a supermassive black hole might give rise to the quasi-periodic eruptions seen in certain galaxies.
Astrobites reports on the possibility that an ancient rogue planet is responsible for the unusual orbits of a trio of solar system objects called sednoids.
Researchers investigate the behavior of minidisks: the small disks of gas that collect around the individual supermassive black holes in a binary pair.
To speed up their models of supernovae, astronomers are turning to neural networks for an AI-assist.
New research challenges expectations that the smaller a planet is, the faster it will lose its atmosphere when exposed to fierce stellar winds and intense radiation.
Astrobites reports on a class of stars known as complex periodic variables and the possible causes of their variations.
