The face and big ears are not Mickey's, just three overlapping craters in Mercury's southern hemisphere. The look-alike picture was shot by NASA's Messenger spacecraft, currently in orbit around the solar system's innermost planet. Images taken when the sun is low on the horizon help scientists see the planet's small-scale surface features because of the long shadows. The three-crater configuration is near a larger crater called Magritte, the space agency reports. Click Here for Pictures: Final Frontier Messenger, launched in 2004 on a long orbital tour of the inner solar system, went into orbit around Mercury in 2011 after flying by in 2008. The long trip was plotted as a way to use a smaller, less expensive rocket to launch the ship from Earth. ABC's Ned Potter contributed to this report.
