What are quasars?

6:28 AM by Lens Moment


The name quasar is short for quasi-stellar radio source.Quasars appear to be stars,but they have large red shifts in their spectra indicating that they are receding from the Earth at great speeds,some up to 90% of the speed of light.Their exact nature is still unknown,but many believe quasars to be the cores of distant galaxies,the most distant objects yet seen.Quasars were first identified in 1963 by astronomers at the Palomar Observatory.
