This image, taken with the Atacama Large Millimeter/submillimeter Array (ALMA), shows the molecular gas content of two galaxies involved in a cosmic collision. The one on the right hosts a quasar –– a ...

Galaxies formed and grew billions of years ago by accumulating gas from their surroundings, or colliding and merging with other young galaxies. These early stages of galaxy assembly are believed to be ...

Astronomers have used a pair of Mauna Kea telescopes to shed light on one of the universe’s earliest stages of development. Using the Gemini North and Subaru telescopes, a team led by astronomer ...

UK astronomers using the 15-m James Clerk Maxwell Telescope in Hawaii have discovered enormous quantities of cosmic dust in the most distant quasar yet observed. The quasar, called SDSS J1148+5251 is ...

Quasars, the luminous beacons at the centers of distant galaxies, have puzzled astronomers for decades with their dramatic brightness variations. Recent observations suggest that these celestial ...

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

The Hubble Space Telescope captures the closest look yet at the host galaxy of a quasar. Credit: NASA / ESA / Bin Ren / Joseph DePasquale The Hubble Space Telescope captured some weird, unidentified ...

Intense radiation emitted by active supermassive black holes—thought to reside at the center of most, if not all, galaxies—can slow star growth not just in their host galaxy, but also in galaxies ...
