I was awestruck looking at this photo with just a pair of cardboard red-blue 3D glasses. Grab your pair and let your eyes climb over the foreground crags and onto the ‘neck’ joining the top and bottom lobes of the comet. A thick blanket of dust appears to cover the area. Did some spill from the spectacular range of cliffs above? And how about the boulders? Did they roll down the same cliffs?
Some of the crater-like depressions in the bulbous foreground lobe are filled with similar but smaller boulders while others liberally pepper the landscape. At front left, check out that huge jagged gash in the comet.
We’ve grown accustomed to detailed, close-up photos of planets and asteroids from our spacecraft and landers, but there’s something about seeing this comet in three dimensions that brings an alien landscape alive. It looks familiar in some respects, but strange and incomprehensible too.
Here are a couple more full-screen variations on the original stereo perspective: 1, 2
I’ve also selectively cropped several areas from the original image:
