Evidence for a thin veil of carbon has been found on the neutron star in the Cassiopeia A supernova remnant. This discovery resolves a ten-year mystery surrounding this object. In Earth's time frame, the estimated age of the neutron star in Cas A is only several hundred years, making it about ten times younger than other neutron stars with detected surface emission. Therefore, the Cas A neutron star gives a unique window into the early life of a cooling neutron star.
