By studying the formation and evolution of galaxies in the early universe, researchers seek to test the predictions of our leading theory of cosmology.
New research proposes a way for fast radio bursts to escape the confines of a magnetized star and jet out into space — by getting help from theoretical particles called axions.
Supermassive stars might explain the unusual amounts of nitrogen in one of the most distant known galaxies, GN-z11.
JWST images of early galaxies have turned up a population of flat, red disks that may have been entirely missed by previous surveys.
Gamma-ray bursts are the most luminous explosions in the universe, and we’ve learned much about these superlative outbursts since their discovery in 1967.
Astronomers have taken a closer look at a system containing three stars and five planets and may have solved a mystery around its formation.
The seeds of supermassive black holes could show up in an upcoming sky survey with JWST.
What’s the mechanism behind millisecond-duration bursts of radio energy coming from outer space? A team searched for visible-light counterparts to constrain the origin of fast radio bursts — and found one.
