Supernova

Above and Beyond: Supernova 1987A

In 1987, astronomers saw the brightest supernova seen on Earth in 400 years. Shortly after its launch in 1990, Hubble observed three rings of gas and dust ejected by the star before it exploded.

 Stars and red gases in space. A bright red sphere in the center. 


Text, SN 1987A SUPERNOVA. In 1987, astronomers spotted the brightest supernova seen on Earth in nearly four centuries. 


Soon after its launch in 1990, the Hubble Space Telescope discovered three rings of gas and dust around the blast site that were ejected by the star before it exploded. 


The red sphere enlarges. There are distinct rings of red and pink dust. 


Since then, Hubble has watched the innermost ring light up, bit by bit, as a shock wave set off by the supernova slams into the ring. 


The star in the center of the ring darkens to purple. The ring turns progressively from orange to white in flashes.
