Unique supernova remnant
Embedded in the heart of a supernova remnant 10,000 light-years away is a stellar object the likes of which astronomers have never seen before in our galaxy.
At first glance, the object looks like a densely packed stellar corpse known as a neutron star surrounded by a bubble of ejected stellar material, exactly what would be expected in the wake of a supernova explosion.
However, a closer 24.5-hour examination with the European Space Agency's XMM Newton X-ray satellite reveals that the energetic X-ray emissions of the blue, point-like object cycles every 6.7 hours — tens of thousands of times longer than expected for a freshly created neutron star.
One explanation for the neutron star's strange behavior is that it might be a magnetar, an exotic subclass of highly magnetized neutron stars. Of the dozen or so magnetars that are known, however, most usually spin several times per minute — much faster than 1E.[1E161348-5055] |
