SN 1987A was a supernova in the outskirts of the Tarantula Nebula, in the Large Magellanic Cloud (a nearby dwarf galaxy). This was close enough to be easily visible to the naked eye and it could be seen from the Southern Hemisphere. It was the closest observed supernova since SN 1604, which occurred in the Milky Way itself. The light from the new supernova reached Earth on February 23, 1987. As the first supernova discovered in 1987, it was labeled 1987A . Its brightness peaked in May, with an apparent magnitude of about 3, and slowly declined in the following months. It was the first opportunity for modern astronomers to study the development of a supernova in great detail, and its observations have provided much insight into core-collapse supernovae. • SN 1987A provided the first chance to confirm by direct observation the radioactive source of the energy for visible light emissions, by detecting predicted gamma-ray line radiation from two of its abundant radioactive nuclei. This proved the radioactive nature of the long-duration post-explosion glow of supernovae. #space #astrophysics #universe Find us on Odysee: • https://odysee.com/$/invite/@SpaceTel...
