This image shows the suspected progenitor of a new kind of supernova called Type Iax. Material from a hot, blue helium star at right is funneling toward a carbon/oxygen white dwarf star at left, which is embedded in an accretion disk. In many cases the white dwarf survives the subsequent explosion (Christine Pulliam / CfA)

This composite image of SN 1604 shows Chandra X-ray emission from iron in blue, and also Spitzer infrared (IR) emission in pink. The IR emission is very similar in shape and location to X-ray emission from material that was expelled by the giant star companion to the white dwarf before the latter exploded. This material forms a disk around the center of the explosion (X-ray: NASA / CXC / NCSU / M.Burkey et al; IR: NASA / JPL-Caltech)
