A supernova of a star more than about 10 times the size of our sun may leave behind the densest objects in the universe— black holes. The Crab Nebula is the leftover, or remnant, of a massive star in our Milky Way that died 6,500 light-years away.

Latest Supernovae - Purdue University
Here you will find a list of the supernovae we can see right now, as well as information about where they are in the sky, images of that object and how bright the explosion was at the last time we measured it. The data on this page comes from TNS and ATEL circulars.
15 Facts About Supernovas: The Universe’s Biggest Explosions
During a supernova, temperatures and pressures become so extreme that nuclear reactions produce elements heavier than iron. This process, known as rapid neutron capture or the r-process, builds atomic nuclei in fractions of a second.
