Eventually the star runs out of efficient fusion reactions (once iron is formed), and the core collapses in a violent explosion \u2013 a supernova. Leaving behind. an extremely dense core, containing the mass of the sun within a 20 km. radius \u2013 the size of a small asteroid! These neutron stars rotate very rapidly due to the conservation of angular. momentum, and some that emit radio waves are known as pulsars for their. rapidly pulsed radio emission.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
