Question

Most quasars seem to be at distances greater than 5 billion light years from Earth. Which of the following can best be inferred from this observation?

A) Quasars existed near the beginning of the universe.
B) Quasars give off very little visible light.
C) Quasars are in the centers of galaxies.
D) Quasars are associated with large black holes.
E) Quasars exist in galaxies like the Milky Way.

Answer 1

Quasars are in the centers of galaxies.

Step-by-step explanation:

Observations with the Hubble Space Telescope provided the strongest evidence showing that quasars are located at the centers of galaxies. Quasars can outshine their entire galaxies by factors of 10 to 100 or even more. When this light passes through Earth's atmosphere, it is blurred by turbulence and drowns out the faint light from the surrounding galaxy. Therefore, we can infer that quasars are in the centers of galaxies.
