Browsing: Neutron Star
A neutron star is the collapsed core of a massive star that has exploded in a supernova, leaving behind an incredibly dense object composed almost entirely of neutrons. Though typically only about 20 kilometers across, neutron stars can contain more mass than the Sun, resulting in extreme gravity, magnetic fields, and rotational speeds. These cosmic remnants are laboratories for physics under conditions that can’t be replicated on Earth, offering insights into matter at nuclear densities, gravitational waves, and the behavior of space-time itself. Ongoing research continues to uncover their role in stellar evolution, cosmic collisions, and the origins of heavy elements.
