Explanation: No one on Earth sees the Moon rotate like this. That's because the Moon is tidally locked in synchronous rotation, showing only one side to denizens of our fair planet. Still, given modern digital technology, combined with many detailed images returned by the Lunar Reconnaissance Orbiter (LRO), a high resolution virtual Moon rotation movie can be composed. In fact, the featured time-lapse video starts with a view of the familiar lunar nearside and quickly finds the Mare Orientale, a large crater with a dark center that is difficult to see from the Earth, rotating into view just below the equator. In a complete lunar rotation condensed into 24 seconds, the video clearly shows that the Earth-facing nearside of the Moon contains an abundance of dark lunar maria, while the lunar farside is dominated by bright lunar highlands. Of course, you can just join other moon-watchers under hopefully clear skies tonight. Check out the sunlit portion of the lunar nearside on International Observe the Moon Night.
