Astronomers with the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) have used data from the project to make the ...

Astronomers have puzzled for decades over how massive elliptical galaxies appeared so early in cosmic history. The standard picture suggests large galaxies slowly assembled through repeated mergers ...

Scientists have discovered that active supermassive black holes don't just kill their home galaxies, but can also eradicate star formation for their neighbors.

Scientists traced star-forming gas clouds in a nearby lenticular galaxy, NGC 1387, offering new insight into early-type ...

An international team of scientists led by the Institute of Cosmos Sciences at the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC) has presented REGALADE, an ...

Astronomers have confirmed a bright galaxy called MoM-z14 that already existed just 280 million years after the Big Bang.

Called CDG-2, this newly identified “ghostly” galaxy may be one of the most dark matter-dominated galaxies ever discovered, with a staggering 99% of its total mass made up of dark matter — a ...

New research reveals that active supermassive black holes can suppress star formation in neighboring galaxies across vast ...

Gas streams gush into the Milky Way 's center and pile up into thick clouds, but for some reason, those ingredients don't ...

A galaxy made almost entirely of dark matter, an elusive form of matter that doesn’t interact with light, was spotted by Hubble 250 million light-years from Earth.

Astronomers have spotted a galaxy so faint, it’s almost invisible — a discovery that could help illuminate one of the most ...

Astronomers using the James Webb Space Telescope have spotted the most distant “jellyfish galaxy” ever seen — a cosmic oddity streaming long, tentacle-like trails of gas and newborn stars as it speeds ...
