description Sagittarius A East Overview
Sagittarius A East is a radio nebula located near the galactic center of the Milky Way. It represents the expanding remains of a supernova explosion, likely a Type Iax event that occurred approximately ten thousand years ago. This shell-shaped structure emits detectable radio waves and offers astronomers a unique opportunity to study stellar death events and their impact on surrounding interstellar material. Researchers investigate it for insights into extreme astrophysical phenomena, primarily benefiting those studying supernovae and galactic evolution.
