Definitions

Short Definition
A quasar is an extremely bright and distant object in space that releases enormous amounts of energy. It is thought to be powered by a supermassive black hole at the centre of a galaxy. Quasars were first discovered in the early 1960s.

Detailed Definition
A quasar, or quasi-stellar radio source, is an incredibly luminous and distant celestial object emitting vast amounts of energy across various wavelengths. Powered by a supermassive black hole at the centre of a galaxy, quasars appear as star-like points of light but are located milliards of light-years away from Earth. They emit radio waves, visible light and X-rays, making them valuable for studying the early universe. Quasars' immense brightness provides insights into galaxy formation, black hole evolution, and the nature of spacetime. Despite their small size, quasars outshine entire galaxies and continue to captivate astronomers in their quest to unravel the secrets of these cosmic powerhouses.

Etymology
The term "quasar" is an abbreviation of the phrase "quasi-stellar radio source." It originated in the early 1960s when astronomers first discovered and studied these enigmatic celestial objects

Sample Sentence(s)

1. In 1963, the first measurement of the distance to a quasar — a radio source that looks like a star in visible light — showed it to be an enormously powerful beacon lying billions of light years away.
