A new discovery has now added to the mystery surrounding these incredibly rare neutron stars. For the first time ever, scientists have detected a vast cloud of high-energy particles called a “wind nebula” surrounding a magnetar — in this case, a magnetar named J1834.9 located roughly 13,000 light-years away near the central part of our galaxy.
