Image Caption: Supernovae ejecta from SN1987A have finally begun to collide with a shell of gas blown out by the star some 30,000 years earlier. We are about to see, for the first time in history, a supernova remnant in the making. A team at the National Science Foundation's Cerro Tololo Inter-American Observatory led by Patrice Bouchet of CTIO used this coutour plot of emission brightness to discover the new impact sites.
The most intense of their newly discovered "hot spots" is south-east of the first hot spot, on the north side of the ring. Other possible impact sites (colored red) are found distributed around the ring.
