(.#198).- The unknown object that passes through the Solar System is not an alien ship?
The unknown object that passes through the Solar System is not an alien ship (a priori).

Two American teams have turned their large radio telescopes to try to record a possible signal that would be emitted by the strange asteroid that crossed the Solar System in October 2017.
The flash passage in mid-October of a foreign asteroid to the solar system, surprised the scientific community. And when astronomers observed that the object called 'Oumuamua seemed to have a very elongated shape, like a big cigar several hundred meters long, it gave free rein to all the fantasies: and if it were an extraterrestrial vessel, passing through our solar system?
Two teams of extraterrestrial signal search, the Seti Institute and the program Breakthrough Listen, have not resisted the temptation to turn the antennas of their radio telescopes to try to record signals that could be emitted by the object. But neither the small antennas of the Allen Telescope Array in California, nor the giant 100m diameter parabola of the Green Bank Observatory in West Virginia have detected any signal that has been emitted since 'Oumuamua. So disappointment for fans of aliens and flying saucers!
Harvard University astrophysicist Avi Loeb, who advises Russian billionaire Yuri Milner in his program Breakthrough Initiatives for Tracing Alien Life, warned before the attempt that there was little chance of detecting anything. whatever. Although the elongated shape, the most suitable for reducing impacts at very high speed during interplanetary travel, does not resemble any known natural form in the solar system, its rotation is too slow to produce any artificial gravity useful in the object. . There is little chance that it is artificial, had explained the researcher to the site of the magazine Scientific American.
Despite this first unsuccessful attempt, the program Breakthrough Listen will continue listening, expanding the range of radio frequencies. But time is running out because the object is already halfway to Jupiter and continues to move more than 93,000 km / h which will make observations quickly impossible.
