For Quasar we have terms and definitions in 3 topics. The topics are Astronomy, Explosives and Solar Physics.

Quasar (Astronomy)

A Compact, extra-galactic object which emits huge amounts of energy, but looks like a point of light. Black holes are thought to live at the center of quasars. Several thousand quasars are known. Quasar is actually short for quasi-stellar object (QSO).

Quasar (Explosives)

Quasar or quasi-stellar object, one of a class of faint blue celestial objects, starlike in appearance, that are currently believed to be the most distant and most luminous objects in the universe. The spectral lines of quasars have enormous Red Shifts that seem to imply that they are receding from our galaxy with speeds as great as 80% of the speed of light. If Hubble’s Law for the expansion of the universe is extrapolated to include quasars, they may be as far as 8 billion Light-Years away and consequently as luminous intrinsically as 100 galaxies combined.

Quasar (Solar Physics)

A faint blue, star-like object commonly considered to be extremely distant, probably an unusual nucleus of a galaxy. It has a tendency to flare.
