This one, in a photo snapped by the Lunar Orbiter, has been named "the shard" or "the tower," by Richard C. Hoagland, who comments on this photo at "Richard Hoagland's Lunar Anomalies." Taken from a distance of about 250 miles, the strange structure (if that's what it is) would be enormous - seven miles high, by Hoagland's calculations. (The star-like shape above the tower is a camera registration mark.)
It's difficult to believe that such a huge structure actually stands on the moon... so what are we seeing in this photo? Is it a plume of "smoke" from some lunar gaseous emission? Are we seeing the ejecta from a meteorite impact? What is it?
