quasi-stellar radio source

Quasars, or quasi-stellar radio sources, are the most luminous objects known.

These objects were dubbed quasars, for quasi-stellar radio sources.

This interpretation accounts for the name quasar, for quasi-stellar radio source.

These were named Quasi-stellar radio sources, or quasars.

Quasars (short for "quasi-stellar radio source") were one of the first point-like radio sources to be discovered.

"A quasar - quasi-stellar radio source.'

A quasi-stellar radio source (quasar) is a very energetic and distant galaxy with an active galactic nucleus (AGN).

For this reason, Cygnus X-1 is identified among a class of objects called microquasars; an analog of the quasars, or quasi-stellar radio sources, now known to be distant active galactic nuclei.

Its course correction would be timed to coincide with the probe's eclipsing a distant quasi-stellar radio source in another galaxy: if there were detectors set up on Saigo's planet, perhaps they would believe the burst of gravity waves came from the quasar instead.

The British scientific journal, Nature, published an article by Maarten Schmidt entitled "3C 273 : A Star-Like Object with Large Red-Shift", marking the first announcement of the discovery of a quasar (quasi-stellar radio source).

The discovery created quite a stir - though not so great as the finding three years later by other astronomers that the source of the signal wasn't a star within our galaxy, as Sandage and Thomas had assumed it to be, but something else 1.5 billion light-years away, earning it the name quasi-stellar radio source, or "quasar."

A quasar (or Quasi-Stellar Radio Source) occurs when gas near a supermassive black hole at the centre of a distant galaxy goes into the black hole (at very high speed), but electromagnetic forces cause it to swirl around above the hole and blast off into space in the form of huge jets of energy.
