Titanic Stellar Explosion

Shock waves from supernova explosion collide with gas ring!!
The supernova explosion was first observed on February 23, 1987. Although the star actually blew up long ago, the light from the explosion had just arrived at Earth.
As the explosion hits the ring very fast and hard, the ring lights up. The lit ring will also light up the space around it, showing objects that were too dark to see before.
Astronomers hope to answer questions about the supernova's past, such as what kind of star caused the explosion.
