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.

Check back next week for another WITU challenge!

  1. Looks like a Chandra image, but I don’t know which one. Yankees 2, Phillies 1 bottom or the 3rd game 6

  2. Of course, it could be the Small Magellanic Cloud after Captain Riker and his crew on board the USS Titan finish destroying a large chunk of it without violating the Prime Directive. Space craft in this case would be a subspace telescope.

  3. It’s clearly a nebula doing an impression of Wile E. Coyote scratching the back of his head.

    ;-P

    Or am I alone on this???

    KultiVator

  4. This one is a real challenge!

    From the colours, I’d say it’s a multi-waveband composite, with the purple x-ray (or, perhaps, Fermi gamma).

    If so, then it would have to be a well-named galaxy (NGC something, or MCG, etc; not SDSS or 2dF or …), unless it were a galactic nebula, perhaps a highly unusual SNR (but that’s unlikely, given the absence of other ‘stars’).

  5. This is SNR 0104-72.3: by Chandresharkar. Though we are not supposed to post the web site for the object.

    LC

  6. Hey look. They actually found Bender floating in interstellar space. You can let the monks out of the closet now!

  7. HA Ha! trying to catch me out here its unmistakably the ectoplasm fuzzy four shaped nebula, captured by a photon spectral hd x pixlation lens.everybody knows that,
