It is roughly 20 kilometers wide and densely packed with neutrons. Not only are neutron stars tremendously dense, they are also incredibly hot. Whereas a 1000-degree Fahrenheit charcoal fire glows red, young neutron star surfaces are over a million degrees and “glow” in X-rays.
Some neutron stars spin at a very rapid rate about /second, they generate very high electric and magnetic field along with the rotation, accelerate particles to that go along the rotation axis flashing a light. That object is called a “pulsar”
This kind of neutron star emits periodic bursts of radio waves, X-rays and gamma rays. The first pulsar was discovered in 1967 by Cambridge University researchers Jocelyn Bell Burnell and Anthony Hewish – though their existence had been predicted more than three decades earlier by Fritz Zwicky and others.
Even though, pulsars were found nearly 40 years ago. Till now, scientists does not know how these fields are oriented, how they accelerate particles to such great energy, or how they convert this energy into radio and gamma rays.
