Here’s this week’s image for the WITU Challenge, a spooky Halloween version, 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. An added “bonus round” this week: name the circular feature in the image, too. 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 is now posted below.
This is a picture of auroras over Earth, specifically Canada with the large Manicouagan impact crater in the foreground. Clouds and Earth’s surface are illuminated by moonlight. The image was taken from the International Space Station by Mr. Wizard himself, astronaut Don Pettit. Read more about Pettit and his photography and wizardry at [email protected]
Check back next week for another WITU challenge!
