http://shadowboxent.brinkster.net/moon/esjmoon.html The August, 2003 issue of Electric Space Craft, a scientific journal, contains an amazing series of images taken from NASA footage included in the TV program, NOVA: To the Moon. The significance of the images has only recently been noticed.
As Apollo 8 orbited 70 miles above the lunar surface, with Earth in the background, it filmed the ground below. At one point, a small, black object, tall and cylindrical, appears jutting from the moon. Just as the camera is about to pass by, the strange object clearly releases a jet-like cloud. It looks like a smokestack ejecting a puff of smoke. The cloud drifts to the right and then dissipates. Though the black object appears small on the screen, it must be thousands of feet tall if the footage was taken from such a high altitude.
Included below are the black and white stills used in the Electric Space Craft issue. We have assembled these into an animated gif that reproduces the NASA footage. The black and white stills are frames from the footage, posted in order from left to right. As you can see, the anomaly first appears near the center of the frame, then descends toward the lower left-hand corner as the camera moves forward. The additional color stills were sent to us by the publication.
