From the explanation

“In 1963 astronomers were astounded to discover that certain faint, star-like objects have very large redshifts . The large redshifts imply that these objects, now known as quasars (QUASi-stellAR objects), lie near the edge of the observable Universe.”

— APOD editors, October 22, 1995
