Quasars

Definition of Quasars as it relates to Science, Astronomy, Astrophysics

Quasars are incredibly luminous and energetic objects found in the distant universe. They are powered by supermassive black holes, which can have masses millions to billions of times that of our Sun. As matter falls into these black holes, it forms an accretion disk that heats up and emits intense radiation across the electromagnetic spectrum. This radiation can be so powerful that quasars often outshine their host galaxies, making them visible across vast cosmic distances. Quasars are thought to represent a crucial stage in galaxy evolution, providing insights into the interplay between black holes, galaxies, and the large-scale structure of the universe. In this hierarchy, Quasars fall under Astrophysics and contribute to our understanding of Science and Astronomy as well.
