This is an image of an expanding shell of hot gas blasting away from a supernova that exploded in 1987. This photo was taken by Hubble in 1994, 7 years after the supernova.
This is a small portion of the Cygnus loop supernova remnant, photographed by the Hubble Space Telescope. This picture was taken in 1991.
Astronomer Johannes Kepler recorded the brightening of a star in the sky in 1604. We now know that this was a supernova exploding in the sky. Here’s a photo of the supernova remnant, taken 400 years after the supernova exploded.
We’ve written many articles about supernovae for Universe Today. Here’s an article about a supernova that exploded in slow motion. And here’s an article about how supernovae might have generated dust in the early Universe.
