Neutron Stars Explained in Simple Words for Laymen
Neutron stars are formed from the core of some starrs. Neutron stars generally have a radius of only around 12 km. With masses exceeding 1.4 times that of the Sun, these are some of the densest objects in the Universe. A tablespoonful of...

NASA | What is a Pulsar?
A pulsar is a neutron star that emits beams of radiation that sweep through Earth's line of sight. Like a black hole, it is an endpoint to stellar evolution. The "pulses" of high-energy radiation we see from a pulsar are due to a...

Crash Course Astronomy #32: Neutron Stars
Neutron stars are incredibly dense, spin rapidly, and have very strong magnetic fields. Some of them we see as pulsars, flashing in brightness as they spin. Neutrons stars with the strongest magnetic fields are called magnetars, and are...
