Scientists have mapped the extent of the Vela Supercluster for the first time, and determined that it is one of the largest ...

The largest 3D map of the universe, created based on data from the Dark Energy Spectroscopic Instrument, shows 47 million ...

The conclusion of DESI's first survey marks an important milestone for cosmology, which finds itself in a bind for the best ...

The universe's first galaxies were hot messes, according to a recent study. During their younger days, they were wild, chaotic bundles of turbulent gas, churned up by huge gulps of intergalactic gas, ...

Ultra-faint dwarf galaxies—tiny satellite galaxies orbiting the Milky Way—have long been seen as cosmic fossils. Now, a new ...

A supermassive black hole, ULAS J1120+0641, outgrows its galaxy and disrupts the cosmic balance, revealing a mystery of the ...

By tracking individual stars and exploding supernovas, astronomers discovered the strength of early ultraviolet glow ...

A monster galaxy from the early universe shows that the cosmos was rich with oxygen when it was only less than 3% of its present age, astronomers have found. The discovery raises questions about how ...

Understanding how galaxies grow has long stood as one of astronomy’s core challenges. Over time, scientists have gathered evidence that galaxy mergers matter. When two galaxies move close, gravity can ...

The Dark Energy Spectroscopic Instrument (DESI) has successfully completed the largest high-resolution 3D map of the universe ...
