NASA recently released this composite image of 9 round objects. 8 of them are the bottoms of frying pans. 1 of them is Europa, a moon of Jupiter. It was taken by NASA's New Horizons space probe in 2007.
Can you guess which is Europa? Attempt no landing there, but make a guess. Then check it against the answer in the Daily Telegraph.
Did you guess correctly?
