Imagine a star so dense and small that a sugar-cube-sized piece of it would weigh as much as a mountain! Welcome to the world of neutron stars. These stellar wonders are formed when massive stars explode in a supernova. The core left behind is crammed with neutrons, making it incredibly dense. A day on a neutron star is just a few milliseconds long because they spin super-fast, sometimes up to 700 times per second! That's like a merry-go-round on hyperdrive! Neutron stars also have super strong magnetic fields, which can create beams of light that sweep across space like cosmic lighthouses.
