Expert Solution
Step 1

Astronomers use the terms the red and blue shifts to measure the distances of the galaxies and heavenly bodies. There is more and more red shifts when an object moves away from the observation points and more blue shifts when it moves towards the observation point.

Quasars are the supermassive objects located at the center of the far away galaxies. The quasars are extremely luminous bodies and are similar like stars which emits the strong radio signals.
