London, Feb 5 (UNI) Shortly after images showing a mystery female figure walking down a hill on Mars, a satellite orbiting it has spotted a smiley face formation embedded in a large crater.
The huge visage stares out from the surface of the red planet, beaming a wonky-faced message of goodwill out in to the solar system, the Daily Telegraph reported.
According to Mars experts, the image is not a somewhat childish piece of interplanetary graffiti, but rather a chance geological formation caused by wind erosion and meteorite impact craters.
Ten days ago Mars-watchers were baffled by what appeared to be the figure of Bigfoot, who had wandered some distance from his more usual roaming grounds in the American Rockies.
Meanwhile, Mercury was discovered to have a large geological anomaly of its own, in the form of a giant spider formation, believed to be unique in the solar system.
