When X-ray pulsars capture the material flowing from more massive companions, that material interacts with the magnetic field to produce high-powered beams that can be seen in the radio, optical, X-ray or gamma-ray spectrum. Normal pulsars spin between 0.1 and 60 times per second, while millisecond pulsars can result as much as 700 times per second. Scientists called them pulsars after their pulsing appearance. As these beams pan past Earth, they flash like the bulb of a lighthouse. Some neutron stars have jets of materials streaming out of them at nearly the speed of light. Some pulsars even have planets orbiting them - and some may turn into planets. The material flows along the magnetic poles of the neutron star, creating X-ray pulsations as it is heated.īy 2010, approximately 1,800 pulsars had been identified through radio detection, with another 70 found by gamma-rays. Stars more than 10 times as massive as the sun transfer material in the form of stellar wind.
