1. Neutron Star: This is the most common outcome for stars that are 8-20 times the mass of our Sun. When these stars run out of fuel, they collapse under their own gravity, crushing their cores into a dense sphere of neutrons. This sphere is only about 12 miles in diameter but can have a mass twice that of our Sun! Neutron stars are incredibly dense and have powerful magnetic fields.
2. Black Hole: When stars larger than 20 times the mass of our Sun collapse, they become so dense that even light cannot escape their gravitational pull. This creates a black hole, a region of spacetime where gravity is so strong that nothing, not even light, can escape.
In summary:
* Neutron Star: A collapsed core of a massive star, composed mostly of neutrons, with a very high density and strong magnetic field.
* Black Hole: A region of spacetime where gravity is so intense that nothing, including light, can escape.
It's important to remember that both neutron stars and black holes are formed by the collapse of massive stars. The difference lies in the initial mass of the star.
