Quasars are extremely luminous and distant celestial objects that are powered by supermassive black holes at the centers of galaxies. Synonyms for quasar include quasi-stellar object (QSO), quasi-stellar radio source (QSRS), and quasi-stellar X-ray source (QSX). These terms were coined in the mid-1960s when quasars were first discovered and were thought to be stars but with unusual spectra. However, it was later discovered that quasars are actually galaxies with massive black holes at their centers, and their powerful radiation and high-energy emissions make them distinct from other types of astronomical objects. Despite this, the term "quasar" has remained the most commonly used name for these fascinating and enigmatic cosmic phenomena.

How to use "Quasar" in context?

Visible galaxies like our Milky Way are collections of stars. The Milky Way alone contains an estimated 200 - 400 billion stars. quasars are much more distant, and when observed with modern telescopes appear as point-like sources of light. Quasars are powered by a supermassive black hole in the center of the galaxy. The intense magnetic fields generated by the black hole cause the light from the quasar to be stretched and redshifted. Some quasars are even thought to emit more light than an entire galaxy of 100 billion stars!
