This is the first map of radioactivity in a supernova remnant, the blown-out bits and pieces of a massive star that exploded. The blue color shows radioactive material mapped in high-energy X-rays using NuSTAR. Heated, non-radioactive elements previously imaged by Chandra using low-energy X-rays are shown in red, yellow, and green. Image Credit/Caption: NASA/JPL-Caltech/CXC/SAO
