What has appeared as a mild-mannered elliptical galaxy in previous studies is revealing its wild side in new images taken with NASA's Hubble Space Telescope. The Hubble photos show shells of stars around a bright quasar, known as MC2 1635+119, which dominates the center of the galaxy. The shells' presence indicates a titanic clash with another galaxy in the relatively recent past. picked by AutumnLotus 12 months ago

Spitzer Space Telescopes show that the vicinities around the black holes could be backing up with excess matter - the black holes just can’t consume it fast enough to clear the space. When this happens, the matter heats up, and releases a tremendous amount of energy. picked by 2manyusernames 2 years ago

An ambitious study of active and inactive galaxies has given new insights into the complex interaction between super-massive black holes at the heart of Active Galactic Nuclei (AGN) and star formation in the surrounding galaxy. The study finds that gas ejected during the quasar stage of AGN snuffs out star formation, leaving the host galaxies to evolve passively. picked by AutumnLotus 6 months ago

Quasars are enormously powerful astronomical objects that emit a galaxy's worth of energy from a region the size of our solar system, and the discovery of these may reveal the new and potentially violent ways that three quasars in close quarters might interact. picked by tundramonkey 2 years ago

Deer can't see cars at night because of blindingly bright headlights. And until now, astronomers couldn't see foreground galaxies outshined by the dazzling quasars behind them. A new technique can pick apart the intense pattern of light emitted by quasars, finding irregularities in the image where "invisible" galaxies are absorbing some of the quasar light. picked by AutumnLotus 1 year ago

this is the closest you'll get to finding prehistoric life in outer space. This cartoon rocked when i was a kid!! It is funny how Quasar always seemed to get invaded? picked by nesbyniccolo 1 year ago
