Chandra X-ray Image of Pulsar in Kes 75
The pulsar is the bright spot near the center of the image. The rapid rotation and strong magnetic field of the pulsar have generated a wind of energetic matter and antimatter particles that rush out at near the speed of light. This pulsar wind has created a large, magnetized bubble of high-energy particles called a pulsar wind nebulae, seen as the blue region surrounding the pulsar. The magnetic field of the pulsar in Kes 75 is thought to be more powerful than most pulsars, but less powerful than magnetars, a class of neutron star with the most powerful magnetic fields known in the Universe. Scientists are seeking to understand the relationship between these two classes of object.
