Want To Find More Supernovae? Follow The Light

Researchers have made progress understanding how supernova blast waves interact with the surrounding medium. The explosions amplify gamma-ray emissions, sometimes for years after the initial explosion. The discovery will help astrophysicists recognize SN explosions and target them for follow-up observations.

Before a supernova finally explodes, its progenitor ejects massive amounts of gas into its surroundings. When the doomed star finally explodes, its blast wave slams into this material. This is one of a supernova’s signatures, and researchers have figured out how to detect it.
