- Astronomers witness the birth of a magnetar for the first time
Astronomers observed the birth of a magnetar through a 'chirping' signal from a distant supernova, confirming these highly magnetic neutron stars can power the universe's brightest stellar explosions. This discovery also marks the first use of Einstein's general relativity to explain supernova mechanics.
- 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.
- Scientists just found a supercharged supernova — powered up by a magnetic star corpse
Scientists discovered a supercharged supernova powered by a magnetar, a highly magnetic neutron star. The finding highlights a rare cosmic event observed in a spiral galaxy with a bright spot.
