(sarcastic answer removed) A quark is a subatomic particle. They are found in protons and neutrons, for instance, which together make up the nucleus of atoms. The word also appears in Finnegan's Wake, in the line "Three quarks for Muster Mark!" The answer is twofold: everywhere, and nowhere. A quark is considered the most elemental of all subatomic particles. Quarks make up other subatomic particles, such as protons and neutrons. Because quarks make up other subatomic particles, and because all matter is made up from subatomic particles, you will "find" quarks in everything you see, touch, smell, and taste. First, quarks are too small to see or measure. Therefore, you could never actually "find" a quark. Second, quarks always - but always - exist in combinations with other quarks to make up other particles. Quarks do not exist alone as free quarks. Therefore, even if you could see them, you could never find just a quark.
Far away and long ago (they were common early in the life of the universe).
Quarks can not be observed directly, due to confinement. Neutrons and protons are made up of 3 quarks each. Several other particles are made up of more than one quark.
Most quasars are far, far away, meaning they were more common in the early Universe. Quasars are related to supermassive black holes, in the centers of galaxies.
Quasar formation is associated with the big bang. The big bang is the model of how the universe was formed.

Twin Quasar was created in 1979.
A type of galaxy is probably the answer you are looking for. However, a quasar is actually an active galactic nucleus.
Quasars are: quasi-stellar radio sources. The consensus now is that: quasars (the most luminous objects in the Universe) are compacted regions in the middle of massive galaxies. Quasars owe their high energy to the accretion discs surrounding massive black holes at the center of these galaxies.

No. Quasars have the highest energy output of any type of object in the known universe.
It is not.
Yes, a quasar is a galaxy with a super-massive black hole in its center. The hole being invisible, all light vanishing from the great gravity. The quasar itself, among the brightest, most luminous objects in the universe, is being powered by an accretion disc around the black hole.
Quasar Padamsee was born in 1978.
Astronomers have detected a quasar in a distant galaxy.
Twin Quasar was created in 1979.
a large redshift in the spectrum of the quasar.
A binary quasar is a pair of quasars which gravitationally interact with each other, unlike a standard double quasar, which does not interact.
Quasar - Wendell Vaughn - was created in 1978.
