Supernova 1987A

Supernova 1987A was a spectacular stellar explosion in the Large Magellanic Cloud, a nearby galaxy. It marked the death of a massive star that collapsed under its own gravity, releasing an enormous amount of energy and light, outshining its entire galaxy for a short time. This explosion created a supernova, leaving behind a neutron star or black hole and dispersing heavy elements essential for planet formation. Its proximity allowed scientists to study the process in detail, helping us understand how stars end their lives and enrich the universe with elements necessary for life.
