SN 1054 (Crab Nebula)

Supernova SN 1054 was a massive stellar explosion observed in 1054 AD, resulting in the creation of the Crab Nebula. When a massive star reaches the end of its life, it can explode violently, ejecting material into space at high speeds. This explosion leaves behind a neutron star—a dense, rapidly spinning core—and the glowing, expanding cloud of gas and dust known as a nebula. The Crab Nebula, visible in the constellation Taurus, is a famous remnant displaying intricate filaments of gas and energetic particles, serving as a natural laboratory for studying extreme astrophysical processes.
