Perplexing Pulsars Explained by Geometric Particle Trails

Photographs of geometrically shaped trails of high-energy particles ejected from two pulsars as they zip through the Milky Way galaxy have helped scientists better understand why the two objects emit very different kinds of light. Pulsars are a type of neutron star that forms following a supernova explosion, when a massive star collapses in on itself. Pulsars spin at varying speeds, and some of them emit steady beams of light.
