Earth Webcam Catches Mars Rotation

Explanation: Mars won't look this good. Tonight and over the next few days, when Mars is at its closest approach to Earth in nearly 60,000 years, you might get your best view ever of our planetary neighbor. Please, though, don't expect to see this much structure, or expect to see Mars rotate so much in so brief a period. The above 20-frame movie was created from 1000 frames of a backyard webcam that were meticulously aligned, added, and digitally sequenced. Pictured, Mars appears to rotate in a time-lapse sequence, with each frame separated by 30 minutes of real time. In reality, one full Martian rotation -- a Martian day -- is only about 40 minutes longer than an Earth day. For those with access to a small telescope, here is how mars will really look.
