How are black hole different from neutron star?

Answer 1

A neutron star is an extremely dense object in which atoms have been crushed by gravity, causing electrons and protons to merge into neutrons. A force known as neutron degeneracy pressure prevents it from collapsing further. The neutron star can emit light and other forms of radiation. A black hole is an object that has completely collapsed under the force of gravity, with all mass coming to a single point called a singularity. The gravity is so strong that, within a certain radius nothing, not even light, can escape.
