NASA’s Fermi telescope reveals the power source behind monster supernovae
NASA's Fermi telescope has detected a gamma-ray signal from a superluminous supernova, marking a significant discovery in astrophysics. The event, known as SN 2017egm, is believed to be powered by a rapidly spinning magnetar, an exotic neutron star. This finding may provide insights into the mechanisms behind the extraordinary brightness of certain supernovae.
- ▪NASA's Fermi telescope detected a gamma-ray signal from the superluminous supernova SN 2017egm.
- ▪The supernova is located 440 million light-years away in the galaxy NGC 3191.
- ▪Researchers suggest that a rapidly spinning magnetar is responsible for the supernova's extreme brightness.

Science News from research organizations NASA’s Fermi telescope reveals the power source behind monster supernovae Date: May 27, 2026 Source: NASA’s Goddard Space Flight Center Summary: NASA’s Fermi telescope has detected what may be the first confirmed gamma-ray signal from a superluminous supernova — one of the most extreme explosions in the universe. Scientists believe the blast was powered by a rapidly spinning magnetar, an exotic neutron star with unbelievably strong magnetic fields. The event, called SN 2017egm, erupted 440 million light-years away and may help explain why some supernovae become extraordinarily bright.
