Neutron Stars
Discover amazing facts about neutron stars, the incredibly dense and magnetic objects formed when massive stars explode
Neutron stars are incredibly dense objects that spin rapidly and emit beams of radiation
Neutron stars are the most extreme objects in the universe! They form when massive stars explode in spectacular supernovas, leaving behind incredibly dense cores. A neutron star is only about 12 miles wide - smaller than most cities - but contains more mass than our entire Sun! They're so dense that just one teaspoon of neutron star material would weigh about 6 billion tons on Earth. That's like squishing Mount Everest into a teaspoon!
Many neutron stars spin incredibly fast and act like cosmic lighthouses, sending out beams of radiation that sweep across space. When these beams point toward Earth, we see regular flashes of light called "pulsars." Some neutron stars spin over 700 times per second - faster than a kitchen blender! They also have the strongest magnetic fields in the universe, trillions of times stronger than Earth's magnetic field.
Five Famous Neutron Stars:
PSR B1919+21 - The very first pulsar ever discovered in 1967 by student Jocelyn Bell Burnell. It pulses every 1.34 seconds like a cosmic heartbeat.
Crab Pulsar - Located in the Crab Nebula, this neutron star spins 30 times per second and is the remnant of a supernova seen by Chinese astronomers in 1054 AD.
Vela Pulsar - One of the nearest pulsars to Earth, spinning 11 times per second and occasionally "glitching" by suddenly spinning faster.
PSR J1748-2446ad - The fastest-spinning neutron star known, rotating an incredible 716 times per second! Its equator moves at 24% the speed of light.
Magnetar SGR 1806-20 - A special type of neutron star with an ultra-strong magnetic field that occasionally releases massive bursts of energy visible across the galaxy.
