NICER Observes Merger of X-Ray Spots on Distant Magnetar

Using NASA’s Neutron star Interior Composition Explorer (NICER), astronomers have noticed the merging of multimillion-degree X-ray spots on the floor of a magnetar known as SGR 1830-0645. Magnetars are remoted neutron stars with extraordinarily highly effective magnetic fields — as much as 10 trillion occasions extra intense than a fridge magnet’s and a thousand occasions stronger than a […]
