Anomalous X-ray pulsars
Tiny stellar 'corpses' have been caught blasting surprisingly powerful X-rays and gamma rays across our galaxy by ESA’s gamma-ray observatory Integral.
This discovery links these objects to the most magnetically active bodies in the Universe and forces scienti...

NASA's Spitzer Space Telescope has found a bizarre ring of material around the magnetic remains of a star that blasted to smithereens. The stellar corpse, called SGR 1900+14, belongs to a class of objects known as magnetars. These are the cores of massive stars that blew up in supernova explosions,...

First optical signals spied from dead star Astronomers believe they have spotted an aurora around of one of the densest objects in the Universe. In the first observation of its kind, researchers say that they have seen optical light from a magnetar, an extremely dense, dying neutron star with a very...
