Quasars

Definition of Quasars as it relates to Science, Physics, Stellar Evolution

Quasars, short for quasi-stellar radio sources, are incredibly luminous celestial objects located at vast distances from Earth. They emit enormous amounts of energy, often outshining entire galaxies and can be seen across cosmic distances. Quasars are thought to be powered by supermassive black holes residing at the centers of galaxies. As matter falls into these black holes, it forms an accretion disk that heats up and emits intense radiation, giving rise to the observed quasar emission. These objects play a crucial role in our understanding of stellar evolution and the early universe, as they provide valuable insights into galaxy formation, supermassive black hole growth, and the interplay between these processes.
