How does a neutron star form?

What is a neutron star and how does it form?

A neutron star is the remnants of a massive star that has exploded in a supernova. It forms when the core collapses under gravity, compressing protons and electrons into neutrons.

What happens during the supernova explosion?

During a supernova, the outer layers of the star are expelled into space, while the core collapses. This explosion can outshine entire galaxies for a short time.

Are neutron stars really dense?

Yes, neutron stars are incredibly dense. A sugar-cube-sized amount of neutron-star material would weigh about as much as all of humanity!

Can neutron stars collide with each other?

Yes, neutron stars can collide, and when they do, they can create gravitational waves and even form black holes.

What are some interesting facts about neutron stars?

Neutron stars can spin very rapidly, some rotating hundreds of times per second, and they have strong magnetic fields that can emit beams of radiation.
