Study Notes
Neutron Stars and Pulsars
- Neutron stars can form from leftover material after a star's collapse
- Spinning neutron stars are called pulsars, emitting pulsating radio signals
Black Holes
- Characterized by extremely strong gravity, trapping everything, including light
- Formed when a white dwarf stops glowing after billions of years, becoming a black dwarf
Supernovae
- Occur when a supergiant star runs out of fuel, leading to a sudden and immense explosion
- The explosion, called a supernova, makes the star shine millions of times brighter within hours
- After the explosion, some of the star's material is left behind
