Beginning with a wide-field view of the supernova remnant IC 443, this sequence moves into a closer look at the neutron star embedded within known as J0617. The images show these objects in X-rays (blue), radio (green), and optical (red). The location and orientation of J0617's wake are mysterious for astronomers who would have expected it to be aligned toward the center of IC 443.
