Die erste Quasar-Generation Astronomen finden erstmals Unterschiede zwischen Quasaren im jungen und im heutigen Universum Nachricht Die Linie gibt Aufschluss über den inneren Akkretionsfluss in unmittelbarer Nähe zum zentralen, superschweren Schwarzen Loch. Astronomen haben das fernste Schwarze Loch entdeckt, das wir kennen:
Have you ever wondered what lies at the center of a galaxy? If you peer at the very center of some galaxies, you may find a curious object called a quasar.
These objects are extremely bright. At that time, astronomers were pointing their radio telescopes toward the sky.
They noticed radio waves coming off of celestial bodies they expected, like the sun. This term was later shortened to quasar.
Quasars are usually found billions of light-years away from Earth! We now know a lot more today about quasars than ever before. The astronomy community has many thousands of quasars cataloged.
A quasar is made up of two key parts. The first is the supermassive black hole. A supermassive black hole is a black hole that is over a billion times the mass of our Sun.
Black holes have very strong gravitational pulls, so they draw in objects around them. As material falls near the black hole, it surrounds it and becomes an accretion disk.
The supermassive black hole and accretion disk are the two parts of the quasar. Maelstrom is destroyed by the Quantum-bands and Quasar resurrects himself.
When a stargate being used by the Shi'ar during the Kree-Shi'ar War threatens to destroy Earth's sun, Quasar is able to undo the damage with the help of Binary.
During the storyline " Infinity War ", Quasar travels to the Dimension of Manifestations to gather intelligence. With the aid of the Contemplator , he discovers the cosmic being Eternity in a catatonic state.
Quasar attempts to use the near-omnipotent Ultimate Nullifier against the god-like villain Magus , but Magus uses the Infinity Gauntlet to turn the weapon against Quasar, wiping him from existence.
Quasar helps defend the universe from aliens called Infinites. Quasar helps to operate an Avengers deep-space sensing station with the support of Living Lightning and Monica Rambeau ,  and then becomes involved in Kang's War.
Quasar is killed by Annihilus. Wendell is restored to life in a Quantum Energy form thanks to the scientists of Project Pegasus.
Wendell volunteers to scout the rip in spacetime that occurs during the " War of Kings " storyline. During the trip, he regains physical form and discovers an alternate universe planning to invade his universe.
In an effort to prevent further galactic catastrophes, Quasar joins the Annihilators. During this time, he works as the curator of the Pleasant Hill museum.
Wendell Vaughn is an athletic man with no inherent superhuman powers. He received extensive training in hand-to-hand combat, and moderate experience in the same.
He is an expert in all basic espionage skills, as a S. While he possessed the power of the Star Brand , Quasar gained the abilities of flight, superhuman strength and resilience.
He also was able to regenerate his entire body from minute remains and did not need to eat, drink or breathe. However, virtually all of the energy derived from the Star Brand was depleted not long after he gave it away.
The Living Tribunal later stated that Quasar's body retains only an insignificant trace amount of energy. Quasar also briefly possessed the same powers of cosmic awareness that Eon granted to Kree soldier Mar-Vell later known as the original Captain Marvel.
By simply concentrating for a moment, he could gain complete knowledge about virtually anything in the universe. While Quasar's powers are quite powerful and diverse, since he doesn't make it a habit of using all of his power to destroy his opponent, it is important to note his standard operating procedure: After a failed war with the Elder God Set and the deaths of every hero on Earth save the Silver Surfer, Quasar is merged with Captain Universe to form a super-being capable of capturing and defeating Set.
Using the Eye of Agamotto, Quasar traps himself and Set within its pocket dimension. Once, during a trip through alternate realities, the Earth version of Quasar viewed his Captain Universe-enhanced counterpart and Set battling each other.
Tricked by Eon's evil "child" Era, Quasar jumps to a sentient nexus of energy and is killed. He ends up in the 'White Room', where all Quantum Band wielders go after death.
Eon is entrapped with him, in the form of a centerpiece on the Room's table. Her, now called Kismet , teams up with the long-lost son she had with Quasar, Starhawk.
They visit Quasar's grave and learn what Era has done. With the aid of the Hawk-God Starhawk worships, the two vow to stop Era.
Wendell Vaughn briefly appears as a scientist in the alternate timeline. There is no indication that he possesses the quantum bands in this universe.
Quasar is briefly mentioned as having gone insane in Last Avengers Story 1, but does not appear. Quasars show the locations where massive black holes are growing rapidly via 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 Earths per minute.
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 near-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 ,  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 multiple-image quasar is a quasar whose light undergoes gravitational lensing , resulting in double, triple or quadruple images of the same quasar.
As quasars are rare objects, the probability of three or more separate quasars being found near the same location is very low.
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.
The first quadruple quasar was discovered in When two quasars are so nearly in the same direction as seen from Earth that they appear to be a single quasar but may be separated by the use of telescopes, they are referred to as a "double quasar", such as the Twin Quasar.
This configuration is similar to the optical double star. Two quasars, a "quasar pair", may be closely related in time and space, and be gravitationally bound to one another.
These may take the form of two quasars in the same galaxy cluster. This configuration is similar to two prominent stars in a star cluster.
A "binary quasar", may be closely linked gravitationally and form a pair of interacting galaxies. This configuration is similar to that of a binary star system.

An even bigger surprise was that continuing observations of quasars revealed that their brightness can vary significantly on timescales as short as a few days, meaning that the total size of the quasar cannot be more than a few light-days across.
