This annotated version of the all-sky map points out several galaxy clusters (e.g., Coma, Virgo, Fornax, and Perseus), point sources (e.g., Sco X-1), and extended supernova remnants (SNR). One of the most conspicuous sources is the North Polar Spur, a bubble of hot gas. Its distance is unknown, so astronomers aren't sure if it's a nearby supernova remnant, or a larger shell associated with the galactic center.
