SN 1987A

SN 1987A was a supernova observed in 1987 in the Large Magellanic Cloud, a nearby galaxy. It marked the death of a massive star, which exploded after exhausting its nuclear fuel. This event was significant as it was the closest supernova seen in over 400 years and provided valuable data for astronomers. The explosion released a vast amount of energy, briefly outshining its entire host galaxy. SN 1987A also produced neutrinos, tiny particles that helped scientists understand the processes occurring during such cosmic explosions. Its study has advanced our knowledge of stellar evolution and the life cycle of stars.
