It spins around at 33 times per second. It is a Neutron Star . It is also called a Pulsar , because it sends 33 pulses per second of light, radio waves, infra red, ultra violet and even X-rays . It is a remarkable object, the remnant of a star larger than the Sun that exploded 900 years ago. The space around has been enriched with the heavy elements produced by the explosion.
Supernova explosions are very destructive but they are vital for our existence.
These explosions have two effects on the interstellar environment. Firstly, when the universe began in the Big Bang, conditions were such that only Hydrogen and Helium atoms existed. Since Helium is chemically inert and Hydrogen only forms a double molecule with itself, there was not a lot of chemistry in the early Universe. It was only after Large stars formed, produced the heavy elements, and spewed them out when they went Supernova, that subsequent stars had the right chemistry to form solid planets like the Earth. We are, indeed, stardust .
