For decades, astronomers have searched for the birthplace of globular clusters, the dense spherical collections of stars that ...

Astronomers using computer simulations have investigated whether a class of star clusters nicknamed "cosmic wallflowers" ...

Distant galaxies that abruptly stopped making stars have puzzled astronomers for years. About 9 billion years ago, during one ...

Stars Reach is the new MMO from Ralph Koster, creative lead on Star Wars Galaxies, and it is a fully physically simulated sci ...

When two black holes orbit each other, they eventually spiral inward and collide in one of the most violent phenomena in the ...

Faced with observations of early black holes and galaxies that weren’t expected to exist, scientists have come up with a ...

Advanced cosmological models suggest up to eight starless dark galaxies lie hidden in the immediate vicinity of the Milky Way. The simulations provide a crucial test for standard theories of cosmic ...

The Bullet Cluster of galaxies might only have half as much dark matter than scientists thought, or perhaps even none at all, ...

A new AI-powered framework could transform how astronomers measure the expansion of the Universe. By analyzing images of Type ...

A faint dwarf galaxy drifting 45 million light-years from Earth may have joined one of astronomy’s strangest clubs. It belongs to a tiny set of galaxies that seem to exist without dark matter.

JWST and radio interferometry caught six massive galaxies colliding 12 billion years ago, while a young supermassive black ...
