The term quasar is a concatenation of quasi-stellar radio source — so called because when they were first identified, astronomers like Hong-Yee Chiu, who coined the term, were completely baffled by these strange interstellar objects.

Hence the name “quasar,” an abbreviation that recognized their starlike properties, and stands for quasi-stellar radio source.

The word “quasar” is an acronym for “quasi-stellar radio source.”

The quasar - short for quasi-stellar radio source - sprays out tremendous amounts of energy and matter, powered by a super-massive black hole at its heart.
