As nutty as it may seem to the uninitiated, the notion of looking for alien artifacts on our own Moon may finally be gaining mainstream scientific traction.
There are good reasons to seriously consider the possibility that at some point in the Earth-Moon system’s storied 4.5 billion year-old history, an alien intelligence may have passed through our solar system; leaving physical artifacts of their visits.
These artifacts would likely entail more than just alien space trash, and would arguably include evidence of alien scientific or industrial activity, such as extremely advanced lunar mining, energy generation; even technology related to lunar nearside Earth reconnaissance.
Or so says Paul Davies, a longtime SETI (Search for Extraterrestial Intelligence) researcher, physicist, and now Director of the Beyond Center at Arizona State University in Tempe.
At least one related paper on the subject is due to presented at the September meeting of the UK SETI Research Network, a group of mainstream British academicians. But even a decade ago, talk of alien lunar artifacts was mostly beyond the ken of anything remotely resembling the mainstream astronomical community.
With the success of crowdsourcing, citizen science initiatives such as SETI@home; Einstein@home; and Cosmology@home however, Davies and a handful of other serious scientific researchers are now advocating marrying crowdsourcing analysis with the images now being catalogued by NASA’s Lunar Reconnaissance Orbiter (LRO).
Since 2009, LRO has been measuring lunar landforms down to half meter resolution; in the process targeting more than 10,000 lunar sites and covering up to 90 percent of the lunar surface. The mission’s current success has resulted in a treasure trove of thousands of very high resolution images, almost all of which could be searched via an citizen science initiative.
Davies thinks the ideal lunar survey would not only include a search for optical anomalies but would go beyond the breadth of LRO’s own mission to include searches for evidence of alien lunar industrial activity.
“[Evidence of past] mining or quarrying could show up in gravimetry or magnetic surveys, even if an ancient mine was buried under the lunar regolith,” said Davies. “We could detect [alien] nuclear waste perhaps from a lunar satellite by looking for localized gamma ray sources from the lunar surface.”
A crowdsource lunar image analysis initiative might use Tomnod-type search software in the same way that volunteers were recruited to search satellite imaging for the missing Malaysian 777.
Davies says at some stage any search needs to be automated and use state-of-the-art software.
“In searching for artifacts, one is looking for ‘something fishy’,” said Davies. “But ‘fishiness’ requires a human decision in advance about a signature of artificiality. There are some simple examples, like right angle edges. But we have little idea what million year-old technology might look like.”
Yet Andrew Siemion, a research astronomer at the University of California at Berkeley, says citizen science projects involving image analysis are relatively straightforward to set up.
“Professional astronomers sometimes suffer from the tendency to discount anything other than our expected signal as instrumental noise or some kind of interference,” said Siemion. “When identifying the unexpected, the eye of an amateur citizen scientist can be just as effective, if not more so, than that of a conditioned professional.”
Volunteers sifting through images as part of a crowdsourcing effort, could make their efforts dual purpose. That is, they might look for orange pyroclastic rocks or even residual vulcanism at the same time they would look for artificial anomalies.
Davies says a search for lunar artifacts should be combined with a search for unusual geological features. However improbable, Davies says planetary scientists need to keep their eyes open for non-random anomalies; even ones on the moon and scrutinize their respective databases to “keep an eye out” for putative signatures of alien technology.
A 1995 academic paper by Ukrainian radio astronomer Alexey Arkhipov argues that only artifacts larger than one meter in size would be found on the lunar surface; with objects smaller than that buried by meters of regolith due to the lunar surface’s continual bombardment by micrometeorites.
Even so, Davies says, the moon is an attractive environment to search for artifacts because they would be preserved for much longer than on Earth (or Mars ). “On Earth, human artifacts get buried in centuries,” said Davies. “On the Moon it takes millions or tens of millions of years.”
However, Davies thinks the case for jettisoned material or junk is stronger than a gadget deliberately left for what might be an unknown and truly immense duration.
Arkhipov argued that the peak of the southern wall of the moon’s nearside crater “Malapert” would make a logical site for alien reconnaissance of Earth, since our planet can always be seen from there.
“Given that the moon is a big place, it pays to narrow the search by such educated guesses,” said Davies. “Lunar lava tubes would preserve artifacts and also provide an attractive location for equipment to be shielded from ultraviolet radiation and meteorites.”
When would alien probes have first arrived in our solar system?
Because Earth is only about a third of the age of the universe, habitable planets in the galaxy could thus have emerged at least 8 billion years ago, says Davies. So, he notes it’s likely that if alien technology ever entered our solar system, it happened a long time ago. Assuming that the number of technological extraterrestrial civilizations remain uniform over time, then Davies says it’s still arguable that our solar system has been visited at least once during that 8 billion year timeframe.
Thus, Davies reasons that the average expectation for a visit is of the order 4 billion years ago and later. But he says even a 100 million years ago is optimistically the most recent timeframe for their arrival. And to think they’ve been here since the dawn of recorded human civilization, he says, would be pretty much a statistical impossibility.
However you cut the numbers, says Davies, you would not expect “recent” visits.
In any event, Davies doesn’t expect that there have been any visits by flesh and blood entities and if there were, he reckons they would have moved on.

there are so many of these kind of postings but i have yet to see anything other than rocks .
go outside and stare at the clouds , you will see all sorts of shapes that could resemble anything you mind wants to see
.
i am not saying that there is nothing to see on the moon but until there are some clear pictures that show anything other than rocks i will reserve my judgment

It still surprises me that we have to suffer with fuzzy images with bad definition, yet we can build telescopes that can see other galaxies perfectly.
Why is it so hard to get some clear close ups of somthing only hundreds of thousands of miles away?!

Fuzzy?
Yeah, not so much.

The LRO Narrow Angle Camera (NAC) imagery is amazing detailed with images with resolutions of up to of 50 centimeters per pixel.

I just looked on LROC (LRO/LROC Target Observation Request)
An the max.Resol. we people get from them is 250 m/pixel.
IMHO absolutely outrageous.
See for yourself (use +/- switches leftside on the moonmap)

Ooh how wonderfull!!!.., you can make a request at NASA to get some F*ckn' BLURRY Images. (Sarcsm)

I'm formally calling on the ATS anomalies community to get on board with this. The professionals see value in what you are doing and rather than see you all as lunatiks (pun intended ) they see you as potential peer co-discoverers.

I respond to your call at arms, JadeStar.
I've already found some anomalies right in the image posted by Rob48.
