The Magnetic Fields of Neutron Stars and Pulsar Wind Nebulae
Quick fact
The magnetic field of a typical neutron star is about 10^12 Gauss, which is a thousand trillion times stronger than Earth's magnetic field. This field is so intense that it shapes a region thousands of light-years across, creating a pulsar wind nebula.
Why this is interesting
Have you ever seen a photo of a glowing, colorful cloud left behind by a star's death? Some of those clouds are not just debris—they are powered by invisible magnetic fields from a tiny, city-sized object spinning hundreds of times per second.
