It’s time once again for another Where In The Universe Challenge. Name where in the Universe this image was taken and give yourself extra points if you can name the telescope or spacecraft responsible for the image. Post your guesses in the comments section, and check back on later at this same post to find the answer. To make this challenge fun for everyone, please don’t include links or extensive explanations with your answer. Good luck!
UPDATE: The answer has now been posted below.
This is a thin crescent of Saturn’s third largest moon, Dione, taken by the Cassini spacecraft’s narrow-angle camera on May 17, 2010, and just released on Sept. 1. Cassini was about 394,000 kilometers (245,000 miles) from Dione, and the image scale is 2 kilometers (1 mile) per pixel. Just like seeing our own Moon as a crescent allows us to better see the craters along the terminator, the lit terrain seen here highlights the craters on Dione, as well.
