With Hubble's help, Shull and his team detected a specific wavelength of UV light emitted from distant quasars about 11 billion years ago.
Other speculations include the hypothesis that quasars are actually white holes instead of supermassive black holes.
The redshift means that the quasars are very far away, more distant than the most distant galaxies we can see.
The quasars are so bright that they probably are consuming their energy resources at a very rapid rate.
They have discovered now , previously unimagined objects - pulsars , quasars , and black holes.
The quasars cannot shine for longer than a few million years with their present luminosity.
Energy is injected into space by quasars in the form of fast, nonrelativistic particles.
Other indications of mega-mergers come from relatively nearby quasars.
Quasars originally meant quasi-stellar object.
They're called quasars.
