Paul Davies and Robert Wagner of Arizona State University (USA) offer analyze hundreds of thousands of pictures of the moon for the search for traces of extraterrestrial life.
After all, aliens could leave messages, scientific instruments, waste or evidence of mining.
Chances of discovery are extremely small, but scientists believe that a computer analysis and crowdsourcing — very cheap event compared to the size of possible sensations. One is not surprising because the project SETI, despite its futility, right?
While researchers shtudiruet pictures yourself. They decided to focus on the images obtained by the American lunar probe Lunar Reconnaissance Orbiter, which in mid-2009 had time to photograph in high resolution about a quarter of the surface of our natural satellite. Scientists have found a landing place "Apollo" as well as the American and Soviet automatic stations. Some of them managed to set only for an unusual shade.
NASA laid out Bole 340 thousand images in the public domain. When the probe will cover the whole moon, their number exceeds a million. The analysis of such a database manually by a small group of specialists — a hopeless exercise.
Experts offer to write software for the search of unusual details: straight lines of solar panels, dust-covered contours of quarries, buildings with domes, etc. Since the moon has no appreciable geological activity, traces of reasonable activity must be maintained for millions of years. As for the impact of meteorites, the seismograph ship "Apollo 12" showed that within 350 km of a collision with a large asteroid (the size of a grapefruit) occurs only once a month. Thus, the researchers point out, the fact that the dust formed by such events could bury a man-made object to leave hundreds of millions of years.
Proof — the entrance to the lava tunnels, which still remain intact and unburied. By the way, inozemlyane could use them to create their bases: they say there is water …
Crowdsourcing — the approach is less effective, because if you want the human eye can see in any picture you know what.
It would be easy to find a message, intentionally left by aliens. For example, it could encapsulate and put in some crater. Another option — a transmitter for safety hidden deep under the lunar soil.
The scientists presented their considerations in the journal Acta Astronautica.
