On August 15, 1977, at 11:45 pm , Ohio’s Big Ear radio telescope received a signal of unknown origin from the constellation Sagittarius . It lasted 72 seconds and was 30 times higher than background noise.
No one heard that signal. The system did not even record it. He simply recorded it in writing and it was not until a couple of days later when Jerry R. Ehman said (and wrote) ‘Wow!’. It was the most intense strange signal we had ever encountered . What came after is 40 years of mystery.
Wow! The story of a sign that left us speechless
The Wow! He had everything he needed to become a pasture of alien theories . In fact, Ehman himself was a member of the SETI project, so the idea that it was a (strange and unexplained) evidence of extraterrestrial life took hold. Was the best candidate
Over time, the enthusiasm cooled . As Ehman explained in 2002 , the alien theory seemed unlikely. “We should have seen her again when we looked for her more than fifty times more; Something suggests to me that it was a signal with terrestrial origin that was simply reflected by some piece of space junk ».
This solves a mystery that is 40 years old
But Ehman was wrong again. As Antonio Paris has just shown, it is not a terrestrial signal. Paris is an astronomer who has spent years turning the Wow! In 2016, along with Evan Davies, proposed that the signal could have been caused by an asteroid , the 266P / Christensen or the P / 2008 Y2, that at that moment was traveling by the solar system.
According to Paris and Davies , these two asteroids have one thing in common: a huge cloud of hydrogen around them. Both celestial bodies were discovered in 2006, so they were not contemplated during signal investigations . As the signal falls near the ‘ hydrogen line ‘, it is perfectly plausible that these clouds were the cause of the ‘Wow!’ Signal.
The thesis was suggestive, but it was not clear that it could be done. So to prove it, Paris devoted the last months of 2016 and the first of 2017 to follow the comet 266P with a radio telescope. And, indeed, the signals he has found fit perfectly with the 1977 signal .
Moreover, Paris has examined other asteroids with similar clouds and has concluded that, if the cause was not 266P, it could have been any other. This is how it solves a mystery of more than 40 years and one of the great hopes of those who continue looking for life beyond our planet Earth.
