- NASA’s Fermi telescope reveals the power source behind monster supernovae
NASA’s Fermi telescope detected a gamma-ray signal from the superluminous supernova SN 2017egm, which is believed to be powered by a rapidly spinning magnetar. The discovery may explain why some supernovae become extraordinarily bright.
- A one-in-a-million supernova seen five times could reveal the Universe’s true speed
A rare superluminous supernova named 'SN Winny,' located 10 billion light-years away, appears five times in the sky due to gravitational lensing. Scientists are using the time delays between its appearances to directly measure the universe's expansion rate, potentially solving a major astronomical mystery.
