Members of the Society For Planetary SETI Research (SPSR) have recently published a paper in the Journal of Space Exploration about certain features on the far side of the moon that appear in the crater Paracelsus C. Titled “Image Analysis of Unusual Structures on the Far Side of the Moon in the Crater Paracelsus C,” it argues that these features might be artificial in origin, meaning someone other than a human being built them and put them there.

Contrary to popular belief, reports of artificial structures on the moon are both common and persistent.  Among the first were from George Leonard’s 1976 book, Somebody Else is on the Moon, and Fred Steckling’s 1981 book, We Discovered Alien Bases on The Moon. There are many more, and from many credible sources, which we will get to later in the article.
