Quasars were once among the brightest and most common objects in the early universe. Today, far fewer of them are observed, ...

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 ...

They may have merged and evolved into a mega black hole inside one of the biggest galaxies in the cosmos. When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...

Astronomers have discovered a double-record-breaking pair of quasars. Not only are they the most distant pair of merging quasars ever found, but also the only pair confirmed in the bygone era of the ...

Quasars are the bright centers of young galaxies powered by supermassive black holes. Most quasars are very distant and faint, making them difficult to observe. One quasar, 0957+561, is ...

NASA’s Hubble Space Telescope is “seeing double.” Peering back 10 billion years into the universe’s past, Hubble astronomers found a pair of quasars that are so close to each other they look like a ...

University of Colorado Boulder astronomers targeting one of the brightest quasars glowing in the universe some 11 billion years ago say “sideline quasars” likely teamed up with it to heat abundant ...
