One of the farthest known quasars seems to have shut down the creation of new stars in all the galaxies within its vicinity. A quasar is a powerful source of light, created by torrid gas orbiting a ...

Supermassive black holes lurk at the centers of massive galaxies, including our own Milky Way. Puzzlingly, supermassive black holes more than a billion times the mass of the sun appear to exist just 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 ...

A distant galaxy has been caught in the act of shutting down. The galaxy, called CQ 4479, is still forming plenty of new stars. But it also has an actively feeding supermassive black hole at its ...

An international team of astronomers reports the discovery of a new hyperluminous quasar. The newfound quasar, which received the designation eFEDSJ0828–0139, has a high star-formation rate and its ...

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 ...

Astronomers have characterized a bright quasar, finding it to be not only the brightest of its kind, but also the most luminous object ever observed. Quasars are the bright cores of distant galaxies ...

Add Yahoo as a preferred source to see more of our stories on Google. An illustration of the recording-breaker quasar J059-4351, the bright core of a distant galaxy that is powered by a greedy ...

This artist's concept depicts a distant galaxy with an active quasar at its center. The "quasar winds" are propelling hundreds of solar masses of material outward into the galaxy disk each year. This ...
