Ein Quasar ist der aktive Kern einer Galaxie, der im sichtbaren Bereich des Lichtes nahezu punktförmig (wie ein Stern) erscheint und sehr große Entdeckung und · Physikalische · Vereinheitlichtes Modell · Blazar. Many astronomers believe that quasars are the most distant objects yet detected in the universe. Quasars give off enormous amounts of energy - they can be a. Before Hubble, quasars were considered to be isolated star-like objects of a mysterious nature. Hubble has observed several quasars and found that they all.

Several dozen nearby large galaxies, with no sign of a quasar nucleus, have been shown to contain a similar central black hole in their nuclei, so it is thought that all large galaxies have one, but only a small fraction are active with enough accretion to power radiation and so are seen as quasars. Some scientists even believe that quasars are distant points in space where new matter may be entering our universe. Two quasars, a "quasar pair", may be closely related in time and space, and be gravitationally bound to one another. But this is only conjecture.
