This Week’s WITU Challenge

by Nancy Atkinson on August 13, 2009

Where in the Universe 66
I’m a day late (sorry!) but here’s this week’s image for the Where In The Universe 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 now been posted below.

This is a dust devil on Mars, captured by the HiRISE camera on the Mars Reconnaissance Orbiter. The white mass is a swirling vortex of dust, and the darker line is a shadow cast by this swirling column of dust. This image is from some of the newest releases by HiRISE, see them all here. Find out more about this particular image here.

Check back next week for another WITU challenge!
