Neutron Stars: Cosmic Giants of Nuclear Matter

  1. Neutron stars are the collapsed cores of massive stars after supernova explosions.
  2. They pack more mass than the Sun into a sphere only about 20 kilometers wide.
  3. Their gravity is so intense that atoms collapse, leaving matter made almost entirely of neutrons.
  4. A teaspoon of neutron star material would weigh billions of tons on Earth.
  5. They rotate rapidly—some spin hundreds of times per second.
  6. Pulsars are neutron stars that beam radio waves like cosmic lighthouses.
  7. Their magnetic fields are trillions of times stronger than Earth’s.
  8. Neutron stars help scientists study matter under extreme pressures and densities.
  9. When two neutron stars collide, they produce gravitational waves and heavy elements like gold.
  10. These stellar remnants are laboratories of nuclear physics on a cosmic scale.
