NASA Missions Unmask Magnetar Eruptions in Nearby Galaxies

NASA Missions Unmask Magnetar Eruptions in Nearby Galaxies
On April 15, 2020, a brief burst of high-energy light swept through the solar system, triggering instruments on several NASA and European spacecraft. Now, multiple international science teams conclude that the blast came from a supermagnetized stellar remnant known as a magnetar located in a neighboring galaxy.
This finding confirms long-held suspicions that some gamma-ray bursts (GRBs) – cosmic eruptions detected in the sky almost daily – are in fact powerful flares from magnetars relatively close to home.
“This has always been regarded as a possibility, and several GRBs observed since 2005 have provided tantalizing evidence,” said Kevin Hurley, a Senior Space Fellow with the Space Sciences Laboratory at the University of California, Berkeley, who joined several scientists to discuss the burst at the virtual 237th meeting of the American Astronomical Society. “The April 15 event is a game changer bec ....

Each January, the American Astronomical Society (AAS) conducts a meeting widely hailed as the “Superbowl of astronomy”, in which astronomers gather from around the world to share their latest results.
Last year it was in Honolulu. But this year, thanks to COVID-19, it was online something that AAS had already practised for smaller meetings as far back as June 2020. Not surprisingly, given the rehearsal, they did a smash-bang job of it. But they also had a remarkable amount to present… plus a lot of fun. ....
