Quasars are awe-inspiring – among the brightest objects in the Universe, behind gamma-ray bursts and supernovae. Unlike other ...

The Hubble Space Telescope has stared deeper into a quasar than ever before, discovering "weird" features in its vicinity. Quasars are the superbright centers of active galaxies, and they're ...

In simple terms, the quasar is very, very bright. Hubble’s Space Telescope Imaging Spectrograph (STIS) can work as a coronograph, and is used to block light from central sources. Astronomers ...

NASA's Hubble Space Telescope has unveiled the closest-ever look at a monster black hole devouring its cosmic surroundings. This supermassive black hole, at the heart of a quasar known as 3C 273 ...

Astronomers used a coronograph, an instrument on the Hubble Space Telescope, to blot out the blindingly bright light of the quasar so they could study its surroundings. Credit: NASA / ESA Black ...

Quasar is short for "quasi-stellar radio source" — bright, star-like objects that emit radio waves and are powered by actively feeding supermassive black holes. The first quasars were identified ...

A quasar is a galactic center that glows brightly ... will accrete onto the central super massive black hole, powering the bright lighthouse. "Thanks to Hubble's observing power, we're opening ...

How supermassive black holes form is even more elusive. Astrophysicists believe these invisible giants lurk at the center of virtually all galaxies. Recent Hubble observations have bolstered the ...

unidentified stuff in the most detailed photos ever taken of the immediate space surrounding a quasar. Quasars, a shortening of the term "quasi-stellar objects," are blindingly bright galaxy cores ...
