1. Neutron stars are getting produced as a result of Supernova bursts. That’s when massive ’regular’ star of 10-29 solar masses got burned it’s typical “Hydrogen-Iron“ cycle and then collapsing into itself under it’s own mass, releasing HUGE amounts of energy and dropping external shells of matter away in an enormous explosion. Energy emitted in that explosion can exceed the energy of a whole galaxy for a short time(hours/days). 2. Neutron star consists of a _very-very-very_ dense matter. Approx density is
