Dense remnant of a massive star
A neutron star is an extremely dense object left behind after a massive star explodes. It packs enormous mass into a very small space.
A neutron star is one of the densest known stellar remnants.
A bright compact star remnant with energetic light around it.
A neutron star is one of the densest known stellar remnants.
A neutron star compresses an extraordinary amount of matter into a very small object. Its gravity is intense and its physical conditions are far beyond normal daily experience.
When a very massive star reaches the end of its life, a supernova can leave behind a compact core. If the conditions are right, that core becomes a neutron star.
Neutron stars show how dramatic the universe can be. They are useful for learning about density, gravity, and the life cycle of massive stars.
Imagine a tiny but incredibly heavy remnant, bright and powerful, left behind after a huge stellar explosion.
