Gamma rays can be generated by supernovae, neutron stars, pulsars and black holes. The light of dwarf stars, pulsars, and quasars also grants Kryptonians different abilities. Some neutron stars emit beams of electromagnetic radiation that make them detectable as pulsars. In a 1960 paper, he noted the similarities between pulsars and quasars. Many millisecond pulsars are found in globular clusters. What is the evolutionary relationship between pulsars and magnetars? In the solar vicinity, these neutron stars outnumber radio pulsars of the same age. Currently there are approximately 130 millisecond pulsars known in globular clusters. The pulses from Millisecond Pulsars (MSPs) are used as a system of Galactic clocks. Tests in stronger gravitational fields are provided by the observation of binary pulsars. The periods of pulsars make them very useful tools for astronomers. A narrow beam of electromagnetic radiation is emitted from the poles of rotating pulsars. Accretion-powered pulsars may drive mass loss. At least eight other binary pulsars have been discovered. Some have suggested that such habitats could be built around white dwarfs and even pulsars.
