qua·sar

 (kwā′zär′, -sär′, -zər, -sər)
n.
A compact, extremely bright celestial object whose power output can be hundreds to several thousand times that of the entire Milky Way galaxy. Quasars are among the most distant objects in the universe and are generally considered to be a form of active galactic nucleus.

[From earlier quas(i-stell)ar (radio source).]

n
(Celestial Objects) any of a class of extragalactic objects that emit an immense amount of energy in the form of light, infrared radiation, etc, from a compact source.

qua·sar

(kwā′zär′)
An extremely distant, compact, star-like celestial object. The power output of a quasar is several thousand times that of the Milky Way galaxy.
Did You Know? "The universe is not only stranger than we imagine," Albert Einstein said. "It is stranger than we can imagine." In the 1960s, astronomers found some very strange objects that we now call quasars in the far reaches of the universe. A quasar is like a far-off floodlight. It appears to be an extremely distant star putting out huge amounts of energy. In fact, just one of these objects can be a trillion times brighter than the sun. All of the radiation that a quasar gives off comes from a small area at its center, and many astronomers believe that the source of the energy is an enormous black hole rotating at the center of a young galaxy. Quasars are among the most distant celestial objects known. Some are more than ten billion light-years away, meaning their radiation has taken ten billion years to reach us. So when we look at quasars, we're observing these objects as they were billions of years ago, and we're able to see part of the early history of the universe.
