Quasar - Origin Story

Ultimately, his lack of a killer instinct makes him a more suitable wielder of the bands. Wendell Vaughn becomes a superhero, using the codename Marvel Boy in his first appearance alongside S.

Quasar journeys to Uranus , where the original Marvel Boy had received the bands. The bands' true nature and origins are revealed to him by the cosmic entity called Eon.

Quasar is offered the role and accepts. As a result, his mind is opened to the true extent of the bands' power, including how to use the bands to teleport via a dimension called the Quantum Zone.

He also battles Deathurge. Quasar meets Uatu the Watcher. After a falling-out with both his estranged father and Eon, he quits his role as Protector of the Universe.

However, Quasar is recreated in an energy form by the cosmic being Infinity and battles Maelstrom and Oblivion.

Quasar saves the universe from collapse. 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.

He is briefly replaced by a supervillain who claims his Quantum Bands for himself but Quasar is able to resurrect himself through means of the Star Brand , which he had acquired during a trip to the New Universe prior to the Infinity War.

When the Presence threatens to kill his loved ones, Quasar fakes his death and leaves Earth. 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 , [29] 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 the Avengers: Standoff! 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. Academy graduate. 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: [43].

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. In Marvel Zombies: Dead Days 1, Quasar is one of the heroes attending the briefing given by Nick Fury about defending their world from the zombie plague.

The group destroys many of the somewhat heroic zombies featured in Marvel Zombies 2. Quasar murders his reality's human Kitty Pryde , holding her underwater until she is forced to turn solid, upon which it is implied that Namor eats her.

Quasar and his zombie cohorts are killed at the end of the series. From Wikipedia, the free encyclopedia. Main article: Captain Universe. Main article: Guardians of the Galaxy team.

Main article: House of M. Quasar is the name of several fictional superheroes in the Marvel Comics universe. They are noted for having worn the Quantum Bands, advanced ancient alien technology that grants the wearer awesome power.

Vaughn is the longest-running Quasar character, and the first to use the name. Avril Kincaid is a S.

While working at Pleasant Hill, a gated community holding super villains brainwashed by Kobik, Avril runs a daycare center as her cover.

After Captain America shuts down the security system at the Pleasant Hill Museum, Kincaid enters it and encounters the curator, a retired Wendell Vaughn.

In the aftermath of the events that transpired at Pleasant Hill, Kincaid becomes the new Quasar with Vaughn acting as her mentor. She is later seen trying to prevent an attack by the Chitauri , but is apparently killed in action.

Her apparent death leads the United States government to give Captain America control of the military and law enforcement, as Steve Rogers also assumes control of Hydra.

After Avril's apparent demise, Wendell Vaughn reassumes the Quasar mantle. However, after becoming trapped in a black hole, Vaughn catches a glimpse of Avril, who is still alive, but lost somewhere in space.

The Quasars' powers are derived from the pair of Quantum Bands fused to the bearer's wrists or more specifically, from the seven gems on each of the bands.

The bands are permanently affixed to the wrists; while he or she can make light bend around them so they appear to be invisible, they are still tangible.

They are linked to their wearer's nervous system and grant tremendous powers of energy manipulation, apparently working the same for each bearer.

Composed of unknown materials, the bands were originally created by Eon to be worn by his designated Protector of the Universe.

Foremost among the bands' powers is the ability to tap into a limitless energy source called the "Quantum Zone".

Quasars can project quantum energy in the form of devastating beams of force or heat. Vaughn more commonly employs them to fashion incredibly durable constructs of solid energy, such as containment spheres or pincers.

He protects himself with a personal force field of quantum energy. The Quantum Bands can also exert control over many other types of energy that are part of the electromagnetic spectrum.

For example, Vaughn once caused a star to emit an enormous solar flare. Although the bands apparently cannot overtly affect psionic energy, Vaughn has programmed them to render him impervious to psionic mental control.

Even such powerful psychics as Moondragon and the Overmind have proven unable to overcome this defense. This does not protect the bearer from magical forms of compulsion.

It is possible to create apertures into and out of the Quantum Zone, thus allowing passage through its infinite, featureless expanse.

Vaughn mainly uses this ability to traverse interstellar distances in a manner similar to hyperspace travel, which he refers to as a "Quantum Jump".

A Quantum Jump has a destructive side effect on the local environment, violently upheaving gravity and tearing holes in the atmosphere on Earth, it would damage the ozone layer.

Vaughn initially refrains from using this ability except when in space or in dire circumstances, but eventually discovers that he can prevent this effect by surrounding himself with a barrier of solid energy before jumping.

The Quantum Bands enable their wearer to fly by manipulating gravitons. The maximum obtainable flight speed is unknown, but Vaughn once made a trip from Earth to Uranus in approximately four years flying non-stop this was before he learned how to quantum jump.

This doesn't take into account the velocity that can be achieved in a short burst of acceleration.

The Quantum Bands' gems possess some capability to analyze and process information as if they were extremely advanced computers.

A test pilot selected to wear the bands proves spectacularly successful at wielding them, but he perishes when the energy output reaches a critical mass beyond his control.

Vaughn dons the bands when the criminal scientists A. Using the bands' power to generate solid energy constructs, he repulses the attack.

When the energy buildup begins to overwhelm him, he decides to simply relax and "go with the flow". To his surprise, the buildup abruptly dissipates.

Vaughn realizes the key to wielding the bands is a flexible will, rather than an indomitable, uncompromising one. Ultimately, his lack of a killer instinct makes him a more suitable wielder of the bands.

This doesn't take into account the velocity that can be achieved in a short burst of acceleration. The Quantum Bands' gems possess some capability to analyze and process information as if they were extremely advanced computers.

This makes it possible to navigate the Quantum Zone and the depths of space. The gems are able to detect, analyze, and track energy emissions across vast distances.

They can also "program" Quasars' quantum energy to register and react to certain preset conditions. For instance, at one time Vaughn had the Earth surrounded with an invisible lattice-work of energy that was designed to act as a global alert system against potential extraterrestrial threats.

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.
