Scientist has found a definitive explanation for the extraterrestrial signal "Wow!"
In addition, the scientist was able to detect several more signals similar to "Wow!". The astronomer found that they all came from comets (266P / Christensen, P / 2013 EW90 (Tenagra), P / 2016 J1-A (PANSTARRS) and 237P / LINEAR), and this confirms their natural origin.
Signal "Wow!" (in Russian "Wow!") was recorded on August 15, 1977 by the Big Ear radio telescope of the Ohio State University. The signal lasted 72 seconds and approximately corresponded to the hydrogen line (with a frequency of about 1420 megahertz and with a wavelength of about 21 centimeters). He was received by a scientist named Jerry Eiman, who left the mark "Wow!" In the margin of an observational journal.

His research, according to Antonio Paris, he conducted over the past two years and came to the conclusion that his initial hypothesis - about the origin of the signal "Wow!" from a comet - confirmed. The culprit of the signal was most likely a comet called 266P / Christensen, the passage of which was observed from July 27 to August 15, 1977 in the vicinity of the constellation Sagittarius. Another comet, P / 2008 Y2, could also have caused the signal, but it is difficult to say for certain, since it can only be observed in 2018.
