Scientists have discovered a galaxy as it was 13 billion years ago, 800 million years after the Big Bang. It contains possible evidence of the universe's first stars and is one of the most chemically primitive galaxies observed ...
We may be more in the dark about dark matter than previously thought, according to a new analysis of distant galaxy clusters. Yale astrophysicist Priyamvada Natarajan, a leading theorist on the nature of black holes and dark ...

Dark matter is thought to make up most of the matter in the universe, but the only way it interacts with its surroundings is through gravity. If two colliding black holes spiral through a dense region of dark matter and merge, ...

Astronomers have discovered two early-universe galaxies where the central black holes appear to have grown far faster than their host galaxies. Observations with the James Webb Space Telescope (JWST) reveal that the black ...
There's so little we know about circumbinary planets—planets that orbit two stars instead of one—that they can feel like the stuff of fantasy. And for good reason: to date, we've only confirmed the existence of 18 circumbinary ...
