By reading the chemical “fingerprints” of a distant galaxy, astronomers reconstructed its 12-billion-year evolution. This new ...

The Hubble Space Telescope has captured imagery of spiral galaxy UGC 2890. The "galaxy lies around 30 million light-years away in the constellation Camelopardalis," according to the Hubble team.

The universe is overrun with dark matter, outweighing the ordinary stuff that stars and planets are made of five-to-one. But some corners of the cosmos are more dominated by the invisible substance ...

LONDON — Astronomers have spotted a galaxy so faint, it's almost invisible — a discovery that could help illuminate one of the most elusive substances in the universe. The researchers found Candidate ...

Abstract: More astronomical data was produced than ever before by the introduction of big sky surveys produced by programs like the Slone Digital Sky Survey (SDSS). By classifying this information, ...
