The opposite of the red shift is the purple shift.
The light from quasars - all quasars - is shifted far to the red side of the spectrum. This means that they are moving away from us, at a very high rate of speed. They cannot be "nearby", for that, and a lot of other sound, scientific reasons.
Quasars still exist.
The Red Shift was created in 2005-06.
They're elliptical shaped and the typically have a red center because of all the red giants that form in this type of galaxy.

One of the most reliable methods employed presently is using Hubbles Laws and Constant, utilizing the red shift. RED SHIFT A+LS (:
No. Quasars are at the centers of distant galaxies.
This phenomenon is called red shift.
The red shift depends on the relative motion of the emitting source and receiving detector. Hydrogen per se has no red shift. There is hydrogen with great red shift (in stars in galaxies far away that are moving rapidly away from us).
The red shift shows the velocity with which an object is moving away from the earth. The red shift of an object is correlated to its distance from the earth and so it is also a measure of the distance.
Quasars are thought to be distant super-massive black holes.
