Neutron Stars: The Most Extreme Objects in the Universe
Summary
PBS Space Time explores the interior of a neutron star, describing the exotic states of matter found within, from the ionized atmosphere to the solid crust of iron nuclei. The episode details the transition through the outer and inner crusts, where electron capture creates neutron-rich nuclei and neutron drip occurs, before reaching the "nuclear pasta" phase of matter. It concludes with the star's core, where neutrons may form Cooper pairs or dissolve into a quark-gluon plasma, highlighting the extreme conditions that exist nowhere else in the modern universe.
