Jelly doughnut mystery solved
Researchers have finally figured out the mystery of a Martian rock known as "Pinnacle Island" which resembles a jelly doughnut. The rock isn't some alien being or the result of a cosmic anomaly. The rock is simply a piece of a larger rock broken and moved by the wheel of NASA's Mars Exploration Rover Opportunity in early January.
This image from the panoramic camera (Pancam) on the Mars Rover shows where the rock had been before it appeared in front of the rover in early January 2014.
