The Crab Nebula M1 in Taurus located on the Perseus spiral arm of our Milky Way, 7000 light years away, diameter is about 12 lightyears
See the fine structures of this remnant of a supernova explosion.
A giant star died here and the explosion was observed by Chinese astronomers and Native Americans (Arizona and Mexico) in 1054 AC.
It was 4times brighter than Venus and for 23days visible even during daytime!!
Other than in case of a planetary nebula, the rare giant stars which are ending in a supernova do not compress to a white dwarf star but implode to an extremely dens neutron star or even a black hole. All the heavier elements are created only under the extreme conditions of a supernova explosion and are in all of us and around us. Also no gold without supernovae
