Lord of the Rings: Astronomers Pinpoint the Location of a Mysterious Neutron Star with Superlative Rings of X-ray Light
23 June 2015 — The largest and brightest set of cosmic rings resulting from echoes of X-ray light has been discovered by a science team that includes a Penn State astronomer. The team used NASA's Chandra X-ray Observatory to discover the beautiful and extraordinary rings, which were produced by an intense burst of energy from a neutron star. Rings of this type give astronomers a rare chance to determine the distance from Earth to an object in our Milky Way Galaxy.
