Caption

This is a study of 3C 397, a supernova remnant shown here in X-rays from NASA's Chandra X-ray Observatory (purple) and Suzaku (blue), indicates the blast arose from a single white dwarf that accumulated matter from a normal companion star. The white dwarf exploded as its mass neared 1.4 solar masses.
