The matter inside a neutron star consists mostly of neutrons, with a few protons, electrons, and other sub-atomic particles. This matter is so dense that an entire neutron star, with a mass greater ...

Substituting can be a tricky art, especially when stars are involved. When massive stars explode, they can collapse into extremely dense — and mysterious — objects known as neutron stars. But neutron ...
