This image of type Ia Supernova Remnant 0509-67.5 was made by combining data from two of NASA’s Great Observatories. The result shows soft green and blue hues of heated material from the X-ray data surrounded by the glowing pink optical shell, which shows the ambient gas being shocked by the expanding blast wave from the supernova.
