Summary

Investigating pulsar 3C58 leaves scientists out in the cold. Keywords: Chandra x-ray observatory, pulsars, supernova, neutron stars, cooling, nuclear forces, cosmic magnetism, 3C58 Astronomers with NASA's Chandra X-ray Observatory have found a pulsating star that's too cool to be believed. The object they discovered is a type of neutron star called a pulsar. Pulsars spin and flash radiation like the spinning lights found on a police car. Understanding how pulsars function could help explain how nuclear forces and magnetism work in our universe. Pulsar 3C58 should have a temperature of about 1.5 million degrees Celsius. However, new readings from Chandra show the star's temperature to be 500,000 degrees cooler than expected. Pulsars form following the supernova explosion of a once-healthy star. The explosion triggers a compression of protons and electrons inside the star's core. The result is a core dense with neutrons and even tinier neutrinos. The neutrinos escape
