Some pictures have been labelled the most compelling-yet evidence of extraterrestrial activity. They feature blurred, oddly out-of-focus spots, which some presume depict some kind of hiding place for paranormal phenomena, The Daily Star reported.
"The blurred areas that don't appear to be naturally occurring, make me wonder what is hiding," one person commented on the newspaper's website.
Other puzzling images most notably capture strange-looking Xs all over the moon’s uneven surface. Reddit user Sumner67 underscored that but for a whole pile of images taken during rover and orbiter trips to Mars and the moon, the idea of life there would have been totally ruled out.
The baffling pictures, which include the famed Martial skull picture, came as amateurish alien experts poked through tons of NASA snaps, which are mostly posted among their website archives.
Many remain, though, unconvinced, saying the bizarre spheres and blurred spots are "a normal phenomenon with impacts":
"Common sense at this point would lead to the idea that there is artificial s*** on both the moon and Mars," Reddit user GlenCompton pointed out.
He went on to say that high speed impacts behave similarly, but the entropy of rock, for instance, is to a great extent slower than water, and "they maintain the crater and drop that springs back a lot longer."
Some Reddit users claimed the aforementioned suppositions are mere incidents involving so-called pareidolia, which means one sees patterns in random data, or just mere fakes.
Meanwhile, NASA and the European Space Agency, which are collaborating with Russia’s space agency Roscosmos, consistently vow to ultimately find evidence for extraterrestrial life. For instance, ExoMars, a joint mission of the latter two, aims to find examples of biological and geological activity on Mars.
Speaking about lunar missions, according to NASA, in 2019 it will award the first contracts for the production of basic components for the global Gateway orbital lunar base, which will serve as a setting for deep-space exploration and studies. It is projected to orbit the moon, as well as operate as a launch point for upcoming manned Mars journeys.
