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. (Credit: M. Weiss/CfA)

This “heavy metal” supernova discovery challenges current ideas of how and where such super-charged supernovas occur. Supernovas are some of the most energetic events in the Universe...
