Shocked by Supernova 1987A
The above photo is of the brightest supernova ever sighted (twenty five years ago). The stream of images above shows the result of a collision that was recorded from 1994 to 2009 by the Hubble Space Telescope. The collision was moving at about 60 million kilometers per hour. The evolving rings of SN1987A are glowing due to shock from the collision.
