Neutron Stars

A neutron star is created when a star (which is at least 1.4 times the mass of the Sun) runs out of fuel and collapses under its own gravity. The compression is so strong that all of the protons and electrons are converted to neutrons and the size of the star is reduced to about a 10 mile diameter, perfectly round smooth ball. Some neutron stars rotate at over 1000 times a second.

  1. and then… – Neutron stars don’t last. They go one of two paths. If they start spinning (no one knows why they start to spin), they turn into pulsars. A pulsar flickers on and off as it spins, think of a lighthouse. If it doesn’t start to spin, it collapses in on itself and forms a black hole.

  2. wait.. – i thought that bigger than average stars blew up to giant red stars and then goes through the super nova process either creating a neutron star or a black hole

  3. I studied it in school – No. The sun will turn into a red giant(approx. 100x it’s current size). A bigger star would make a red supergiant. The supergiant creates a supernova, leaving behind a cloud of debris, such as the crab nebula, and the core, the neutron star. If the neutron star doesn’t spin and turn into a pulsar, it collapses into a black hole.
