Sounds far-fetched, but its existence is not as far out as its name: Hanny's Voorwerp. Example sentences from the Web for quasar The direction of polarization for a quasar is determined by the accretion disk surrounding it.

They are extremely distant and their energy generation is thought to involve a supermassive black hole located in the centre of a galaxy.

Word Origin for quasar C quas i-stell ar object. Schmidt noted that redshift is also associated with the expansion of the universe, as codified in Hubble's law.

If the measured redshift was due to expansion, then this would support an interpretation of very distant objects with extraordinarily high luminosity and power output, far beyond any object seen to date.

This extreme luminosity would also explain the large radio signal. He stated that a distant and extremely powerful object seemed more likely to be correct.

Schmidt's explanation for the high redshift was not widely accepted at the time. A major concern was the enormous amount of energy these objects would have to be radiating, if they were distant.

In the s no commonly accepted mechanism could account for this. The currently accepted explanation, that it is due to matter in an accretion disc falling into a supermassive black hole , was only suggested in by Edwin Salpeter and Yakov Zel'dovich , [23] and even then it was rejected by many astronomers, because in the s, the existence of black holes was still widely seen as theoretical and too exotic, and because it was not yet confirmed that many galaxies including our own have supermassive black holes at their center.

The strange spectral lines in their radiation, and the speed of change seen in some quasars, also suggested to many astronomers and cosmologists that the objects were comparatively small and therefore perhaps bright, massive and not far away; accordingly that their redshifts were not due to distance or velocity, and must be due to some other reason or an unknown process, meaning that the quasars were not really powerful objects nor at extreme distances, as their redshifted light implied.

A common alternative explanation was that the redshifts were caused by extreme mass gravitational redshifting explained by general relativity and not by extreme velocity explained by special relativity.

Various explanations were proposed during the s and s, each with their own problems. It was suggested that quasars were nearby objects, and that their redshift was not due to the expansion of space special relativity but rather to light escaping a deep gravitational well general relativity.

This would require a massive object, which would also explain the high luminosities. However, a star of sufficient mass to produce the measured redshift would be unstable and in excess of the Hayashi limit.

One strong argument against them was that they implied energies that were far in excess of known energy conversion processes, including nuclear fusion.

There were some suggestions that quasars were made of some hitherto unknown form of stable antimatter regions and that this might account for their brightness.

Eventually, starting from about the s, many lines of evidence including the first X-ray space observatories , knowledge of black holes and modern models of cosmology gradually demonstrated that the quasar redshifts are genuine and due to the expansion of space , that quasars are in fact as powerful and as distant as Schmidt and some other astronomers had suggested, and that their energy source is matter from an accretion disc falling onto a supermassive black hole.

This model also fits well with other observations suggesting that many or even most galaxies have a massive central black hole. It would also explain why quasars are more common in the early universe: as a quasar draws matter from its accretion disc, there comes a point when there is less matter nearby, and energy production falls off or ceases, as the quasar becomes a more ordinary type of galaxy.

The accretion-disc energy-production mechanism was finally modeled in the s, and black holes were also directly detected including evidence showing that supermassive black holes could be found at the centers of our own and many other galaxies , which resolved the concern that quasars were too luminous to be a result of very distant objects or that a suitable mechanism could not be confirmed to exist in nature.

By it was "well accepted" that this was the correct explanation for quasars, [31] and the cosmological distance and energy output of quasars was accepted by almost all researchers.

Hence the name "QSO" quasi-stellar object is used in addition to "quasar" to refer to these objects, further categorised into the "radio-loud" and the "radio-quiet" classes.

The discovery of the quasar had large implications for the field of astronomy in the s, including drawing physics and astronomy closer together.

It is now known that quasars are distant but extremely luminous objects, so any light that reaches the Earth is redshifted due to the metric expansion of space.

This radiation is emitted across the electromagnetic spectrum, almost uniformly, from X-rays to the far infrared with a peak in the ultraviolet optical bands, with some quasars also being strong sources of radio emission and of gamma-rays.

With high-resolution imaging from ground-based telescopes and the Hubble Space Telescope , the "host galaxies" surrounding the quasars have been detected in some cases.

Quasars are believed—and in many cases confirmed—to be powered by accretion of material into supermassive black holes in the nuclei of distant galaxies, as suggested in by Edwin Salpeter and Yakov Zel'dovich.

The energy produced by a quasar is generated outside the black hole, by gravitational stresses and immense friction within the material nearest to the black hole, as it orbits and falls inward.

Central masses of 10 5 to 10 9 solar masses have been measured in quasars by using reverberation mapping. Several dozen nearby large galaxies, including our own Milky Way galaxy, that do not have an active center and do not show any activity similar to a quasar, are confirmed to contain a similar supermassive black hole in their nuclei galactic center.

Thus it is now thought that all large galaxies have a black hole of this kind, but only a small fraction have sufficient matter in the right kind of orbit at their center to become active and power radiation in such a way as to be seen as quasars.

This also explains why quasars were more common in the early universe, as this energy production ends when the supermassive black hole consumes all of the gas and dust near it.

This means that it is possible that most galaxies, including the Milky Way, have gone through an active stage, appearing as a quasar or some other class of active galaxy that depended on the black-hole mass and the accretion rate, and are now quiescent because they lack a supply of matter to feed into their central black holes to generate radiation.

The matter accreting onto the black hole is unlikely to fall directly in, but will have some angular momentum around the black hole, which will cause the matter to collect into an accretion disc.

Quasars may also be ignited or re-ignited when normal galaxies merge and the black hole is infused with a fresh source of matter. In the s, unified models were developed in which quasars were classified as a particular kind of active galaxy , and a consensus emerged that in many cases it is simply the viewing angle that distinguishes them from other active galaxies, such as blazars and radio galaxies.

More than quasars have been found [45] , most from the Sloan Digital Sky Survey. All observed quasar spectra have redshifts between 0.

Applying Hubble's law to these redshifts, it can be shown that they are between million [46] and Because of the great distances to the farthest quasars and the finite velocity of light, they and their surrounding space appear as they existed in the very early universe.

The power of quasars originates from supermassive black holes that are believed to exist at the core of most galaxies.

The Doppler shifts of stars near the cores of galaxies indicate that they are rotating around tremendous masses with very steep gravity gradients, suggesting black holes.

Although quasars appear faint when viewed from Earth, they are visible from extreme distances, being the most luminous objects in the known universe.

It has an average apparent magnitude of In a universe containing hundreds of billions of galaxies, most of which had active nuclei billions of years ago but only seen today, it is statistically certain that thousands of energy jets should be pointed toward the Earth, some more directly than others.

In many cases it is likely that the brighter the quasar, the more directly its jet is aimed at the Earth. Such quasars are called blazars. Quasars were much more common in the early universe than they are today.

This discovery by Maarten Schmidt in was early strong evidence against Steady-state cosmology and in favor of the Big Bang cosmology.

Quasars show the locations where massive black holes are growing rapidly by accretion. These black holes grow in step with the mass of stars in their host galaxy in a way not understood at present.

One idea is that jets, radiation and winds created by the quasars, shut down the formation of new stars in the host galaxy, a process called "feedback".

The jets that produce strong radio emission in some quasars at the centers of clusters of galaxies are known to have enough power to prevent the hot gas in those clusters from cooling and falling onto the central galaxy.

Quasars' luminosities are variable, with time scales that range from months to hours. This means that quasars generate and emit their energy from a very small region, since each part of the quasar would have to be in contact with other parts on such a time scale as to allow the coordination of the luminosity variations.

This would mean that a quasar varying on a time scale of a few weeks cannot be larger than a few light-weeks across.

The emission of large amounts of power from a small region requires a power source far more efficient than the nuclear fusion that powers stars.

Stellar explosions such as supernovas and gamma-ray bursts , and direct matter — antimatter annihilation, can also produce very high power output, but supernovae only last for days, and the universe does not appear to have had large amounts of antimatter at the relevant times.

Since quasars exhibit all the properties common to other active galaxies such as Seyfert galaxies , the emission from quasars can be readily compared to those of smaller active galaxies powered by smaller supermassive black holes.

The brightest known quasars devour solar masses of material every year. The largest known is estimated to consume matter equivalent to 10 Earths per second.

Quasar luminosities can vary considerably over time, depending on their surroundings. Since it is difficult to fuel quasars for many billions of years, after a quasar finishes accreting the surrounding gas and dust, it becomes an ordinary galaxy.

Radiation from quasars is partially "nonthermal" i. Extremely high energies might be explained by several mechanisms see Fermi acceleration and Centrifugal mechanism of acceleration.

Quasars can be detected over the entire observable electromagnetic spectrum , including radio , infrared , visible light , ultraviolet , X-ray and even gamma rays.

Most quasars are brightest in their rest-frame ultraviolet wavelength of A minority of quasars show strong radio emission, which is generated by jets of matter moving close to the speed of light.

When viewed downward, these appear as blazars and often have regions that seem to move away from the center faster than the speed of light superluminal expansion.

This is an optical illusion due to the properties of special relativity. Quasar redshifts are measured from the strong spectral lines that dominate their visible and ultraviolet emission spectra.

These lines are brighter than the continuous spectrum. They exhibit Doppler broadening corresponding to mean speed of several percent of the speed of light.

Fast motions strongly indicate a large mass. Emission lines of hydrogen mainly of the Lyman series and Balmer series , helium, carbon, magnesium, iron and oxygen are the brightest lines.

The atoms emitting these lines range from neutral to highly ionized, leaving it highly charged. This wide range of ionization shows that the gas is highly irradiated by the quasar, not merely hot, and not by stars, which cannot produce such a wide range of ionization.

Like all unobscured active galaxies, quasars can be strong X-ray sources. Radio-loud quasars can also produce X-rays and gamma rays by inverse Compton scattering of lower-energy photons by the radio-emitting electrons in the jet.

Quasars also provide some clues as to the end of the Big Bang 's reionization. More recent quasars show no absorption region, but rather their spectra contain a spiky area known as the Lyman-alpha forest ; this indicates that the intergalactic medium has undergone reionization into plasma , and that neutral gas exists only in small clouds.

The intense production of ionizing ultraviolet radiation is also significant, as it would provide a mechanism for reionization to occur as galaxies form.

Quasars show evidence of elements heavier than helium , indicating that galaxies underwent a massive phase of star formation , creating population III stars between the time of the Big Bang and the first observed quasars.

Light from these stars may have been observed in using NASA 's Spitzer Space Telescope , [56] although this observation remains to be confirmed.

The taxonomy of quasars includes various subtypes representing subsets of the quasar population having distinct properties. Because quasars are extremely distant, bright, and small in apparent size, they are useful reference points in establishing a measurement grid on the sky.

Because they are so distant, they are apparently stationary to our current technology, yet their positions can be measured with the utmost accuracy by very-long-baseline interferometry VLBI.

The positions of most are known to 0. A grouping of two or more quasars on the sky can result from a chance alignment, where the quasars are not physically associated, from actual physical proximity, or from the effects of gravity bending the light of a single quasar into two or more images by gravitational lensing.

When two quasars appear to be very close to each other as seen from Earth separated by a few arcseconds or less , they are commonly referred to as a "double quasar".

When the two are also close together in space i. As quasars are overall rare objects in the universe, the probability of three or more separate quasars being found near the same physical location is very low, and determining whether the system is closely separated physically requires significant observational effort.

The first true triple quasar was found in by observations at the W. Keck Observatory Mauna Kea , Hawaii. When astronomers discovered the third member, they confirmed that the sources were separate and not the result of gravitational lensing.

A multiple-image quasar is a quasar whose light undergoes gravitational lensing , resulting in double, triple or quadruple images of the same quasar.

Little is currently understood about the nature of quasars; one theory suggests that they are produced by giant black holes destroying enormous amounts of matter, causing the subsequent ejection of radiation along their north and south poles.

Many astronomers believe that quasars represent an early stage in the evolution of galaxies such as our own. See also blazar Seyfert galaxy.
