QUASAR Meaning and
Definition
-
A quasar is a celestial object that emits incredibly powerful, high-energy radiation. The term "quasar" stands for "quasi-stellar radio source," as they were initially discovered as strong radio sources in the sky. Quasars are believed to be powered by massive black holes in the centers of galaxies, which are surrounded by a disk of hot gas and dust. These black holes are incredibly dense and have an enormous gravitational pull that attracts nearby matter. As the matter falls into the black hole, it heats up and emits high-energy radiation across the electromagnetic spectrum.
Quasars are some of the most distant and luminous objects in the universe and are actively studied by astronomers to understand the early stages of galaxy evolution. Due to their immense distances, they appear as incredibly small and compact sources of light in the sky, resembling stars. However, their energy output is extraordinary and can outshine entire galaxies.
Quasars were first observed in the 1960s and were initially thought to be stars within our own Milky Way galaxy. However, detailed observations and analysis revealed their true nature as distant, extragalactic objects billions of light-years away. They are essential tools in studying the early universe and provide valuable insights into the formation and growth of galaxies and supermassive black holes.
Common Misspellings for QUASAR
Etymology of QUASAR
The word "quasar" is an abbreviation of "quasi-stellar radio source". It was coined in 1964 by a group of astronomers led by Hong-Yee Chiu, who were studying mysterious radio sources discovered in the sky. These objects appeared star-like (stellar) in optical observations, but emitted strong radio waves, hence the term "quasi-stellar". Over time, it was realized that quasars are actually extremely bright and distant active galactic nuclei powered by supermassive black holes at the centers of galaxies. Despite the original name being out of date, the term "quasar" remains in use today.
