Definition of quasar. in English English dictionary

Q

An extragalactic object, starlike in appearance, that is among the most luminous and thought to be the most distant objects in the universe

One of a class of very distant (typically billions of light-years away), extremely bright, and very small objects The term "quasar'' means "quasi-star'' — that is, something that looks like a star but can't actually be a star A typical quasar produces more light each second than an entire galaxy of stars does, and it does so from a region of space which is perhaps as small as our solar system Precisely how they produce their prodigious amounts of energy is not known, but astronomers suspect that their brilliance may be connected with the violent effects of very massive black holes at the centers of distant, dim galaxies on material right around them [See black hole]

{i} quasi-stellar object with a large red shift, distant starlike celestial object that emits massive amounts of radiation (Astronomy)

A faint blue, star-like object commonly considered to be extremely distant, probably an unusual nucleus of a galaxy It has a tendency to flare

–An intense, point-like source of electromagnetic radiation that is characterized by large redshifts in the emission lines Thought to be associated with the early lives of galaxies and perhaps results from the inflow of material onto a massive black hole

An unusually bright object found in the remote areas of the universe Quasars release incredible amounts of energy and are among the oldest and farthest objects in the known universe They may be the nuclei of ancient, active galaxies

A distant, compact, object far beyond our Galaxy which looks star-like on a photograph but has a red shift cbaracteristic of an extremely remote object

An object which appears as a star-like point of light, but emits more energy than an entire galaxy Many quasars also emit radio waves

abbreviation of "quasi-stellar object" Quasars are unusually energetic objects which emit up to 1,000 times as much energy as an entire galaxy, but from a volume about the size of our solar system

Faint star like points of light with peculiar emission spectra Some of the most distance objects in the universe

"quasi-stellar radio source," possibly the most mysterious (and distant) class of objects in the Universe, identified by their immense production of a wide range of electromagnetic radiation despite their relatively small size

Distant, small, bright objects at the core of a young galaxy

A quasar is an object far away in space that produces bright light and radio waves. an object in space that is similar to a star and that shines very brightly (quasi-stellar). in full quasi-stellar radio source Any of a class of enigmatic cosmic objects of high luminosity and strong radio emission observed at extremely great distances; also, a closely related object that has the same optical appearance but does not emit radio waves, i. e., a so-called quasi-stellar object (QSO). Most quasars exhibit very large redshifts, suggesting that they are moving away from Earth at tremendous speeds (approaching the speed of light); they thus are some of the most distant known objects in the universe. Quasars are no more than a light-year or two across but as much as 1,000 times more luminous than a giant galaxy having a diameter of 100,000 light-years; their extreme brightness allows them to be observed at distances of more than 10 billion light-years. Many investigators attribute such energy generation to matter spiraling at high velocity into a supermassive black hole (millions or billions of times as much mass as the Sun) at the centre of a distant galaxy. See also active galactic nucleus

A quasi-stellar object; objects far from Earth, moving extremely swiftly away from Earth, and emitting visible light and radio frequency radiation

an enormously bright object at the edge of our Universe that emits massive amounts of energy In an optical telescope, they appear point-like, similar to stars, from which they derive their name Their high luminosity is created from matter falling into a supermassive black hole in the centers of distant galaxies

from QUAsiStellar Radio Source, an object at large redshift (z>0 1) showing strong broad emission lines Variability shows that the energy must arise in a tiny region, although some quasars have hundreds of time the energy output of normal galaxies Their radio structures often include jets and lobes similar to what we see from radio galaxies

– A starlike celestial object that emits great quantities of light and radio waves; thought to be the ancient exploding origins of new galaxies, quasars are possibly the most distant and oldest observable objects in the universe

Short for Quasi-Stellar object, a stellar event with an extremely large red-shift and among the universes most distant objects

a starlike object that may send out radio waves and other forms of energy; large red shifts imply enormous recession velocities

A small, intense celestial source of radiation with a very large redshift

Objects of small angular size and immense power output Some quasars (quasi-stellar objects, or QSOs) are strong radio sources Radio-emitting quasars were the first to be discovered These are some of the most distant objects in the Universe, and are believed to be fueled by supermassive black holes residing in ancient galaxies

One of over a thousand known extragalactic objects, starlike in appearance and having spectra with characteristically large redshifts, that are thought to be the most distant and most luminous objects in the universe. Also called quasi-stellar object

a star like object that emits radio waves

Puts out tremendous amounts of energy from a very small source Known as the most intense concentrations of energy in the entire universe, quasars shine with the light of a hundred galaxies, but they are no larger than our solar system

A quasar may look like a normal star Upon closer inspection, however, a quasar has a very large redshift Although their exact nature is controversial, quasars are commonly considered to be extremely distant, unusually bright nuclei of galaxies If so, then the light we see from them would have been emitted when the universe was a fraction of its present age See more
