This Week’s WITU Challenge

Here’s this week’s image for the WITU Challenge, to test your visual knowledge of the cosmos. You know what to do: take a look at this image and see if you can determine where in the universe this image is from; give yourself extra points if you can name the spacecraft responsible for the image. We’ll provide the image today, but won’t reveal the answer until tomorrow. This gives you a chance to mull over the image and provide your answer/guess in the comment section. Please, no links or extensive explanations of what you think this is — give everyone the chance to guess.

UPDATE: The answer has been posted below.

This object is the remains of a Type Ia supernova caused by the thermonuclear explosion of a white dwarf. It is called SNR 0104-72.3 (SNR 0104 for short), and is in the Small Magellanic Cloud, a small neighboring galaxy to the Milky Way. The image was taken by the Chandra X-Ray Observatory. The asymmetrical shape of this object is unusual for such a supernova and astronomers think this might be caused by jets in the explosion or clumps of nearby gas.

Find out more about SNR 0104 at the Chandra website.
