Images of DEM L238 and DEM L249

The sequence shows an optical image and then a composite of Chandra X-ray data (blue) and
optical data (white) of DEM L238 and DEM L249, two supernova remnants in
the Large Magellanic Cloud. The view then shows how DEM L238 appears in
the three bands of X-ray emission (low-energy X-rays in red, medium
energies in green and high energies in blue). The central region of DEM
L238 is green which indicates that it is rich in iron, identifying it as
a Type Ia supernova that came from the explosion of a much younger star
than expected.
