A supernova means the complete end of one star. It is a massive explosion of a star that is 10 times more massive than our Sun and the classic nuclear fusion of hydrogen has stopped working there. During the explosion, a large amount of material is released, including heavier elements that were not even initially part of the star and were produced only at the very end, sometimes just before the explosion.
As stars are usually found in galaxies, supernovae are also found in these places. An explosion rarely occurs in our Milky Way, so these supernovae are usually found in other galaxies.
