This image of Type Ia Supernova Remnant 0509-67.5 was made by combining data from two NASA Great Observatories. The result shows soft green and blue hues of heated material from the X-ray data surrounded by the pink optical shell, which shows ambient gas being shocked by an expanding supernova blast wave.
On the wreck of the Balboa was this pair of Annette's Cowries on an inner wall.
