Astronomers Discover “Heavy Metal” Supernova Rocking Out

Client: Harvard-Smithsonian Center for Astrophysics
Date: 2017
Caption: This artist’s impression of SN 2017egm shows the power source for this extraordinarily bright supernova. The explosion was triggered by a massive star that collapsed to form a neutron star with an extremely strong magnetic field and rapid spin, called a magnetar. Debris from the supernova explosion is shown in blue and the magnetar is shown in red.
