Astronomers have discovered a new type of supernova, dubbed a gravitational supernova, which occurred in 1987 in the Large Magellanic Cloud. This is the first time that astronomers have seen this type of supernova, and it provides a unique opportunity to study the behavior of stars at the end of their lives.

The gravitational supernova, named SN 1987A, was observed by the Hubble Space Telescope in 1987. Its discovery marks a major breakthrough in our understanding of the death of stars and the evolution of galaxies. The supernova was caused by the collapse of a massive star, which released vast amounts of energy and created a brilliant explosion. The event was so bright that it could be seen from Earth, and it is the closest supernova to be observed in the past 400 years.
