One of these pictures is Europe, one of the Jupiter 4 big moons. The rest are dirty, old, damaged frying pans. Can you distinguish them? The NASA twitted the challenge in 2015 and the answer is at the end of this post.
Jupiter 4 big moons were discovered by Galileo in 1610. In 1989 a sounding line revealed this moon could have the minimum requirements for life: liquid water, chemical elements and an energy source.
The original frying pans pictures were taken by Norwegian photographer Christopher Jonassen for a project called Devour. In this image NASA intentionally replaced one of the frying pans for the moon Europe.
Have you already discovered which one it is? The answer is the image located at the left of the central stripe. The rest are just frying pans, but we can tell you for sure they are not Castey frying pans.
