Question

the word quasar is a shortened term for quasi - stellar radio source. through a telescope, quasars look like small, faint stars. however, quasars are not related to stars. they are related to galaxies. quasars are related to very distant galaxies. galaxies with quasars in them have very bright centers. some quasars emit a large amount of energy. a quasars energy may be produced by a giant black hole. the black hole may be billions of times the mass of our sun.

1. how is a galaxy with a quasar in it different from other galaxies?

Explanation:

A galaxy with a quasar has a very bright, energetic center (from a giant black hole) emitting large energy, unlike most galaxies which lack such a powerful, bright central source. Quasars make these galaxies appear very bright and emit far more energy, and their energy source (giant black hole) is unique compared to typical galaxy centers.

Answer:

A galaxy with a quasar has a very bright, energetic center (powered by a giant black hole) emitting large amounts of energy, making it much brighter and more energetic than most other galaxies which lack such a powerful central source.
