Hubble Views Edge of Stellar Blast

This Hubble Space Telescope image depicts a small section of the Cygnus supernova blast wave, the result of the "death" of a star 20 times more massive than our Sun 10,000 to 20,000 years ago. Light from this supernova takes around 2,400 years to reach Earth. NASA http://www.nasa.gov/image-feature/goddard/2020/hubble-views-edge-of-stellar-blast
