"I'm not saying it was aliens, but it was aliens," is a phrase that is generally associated with a particular big-haired Ancient Aliens theorist, but Mr. Tsoukalos isn't the only one saying it now.
A new study is looking to extraterrestrial life as the cause of a set of mysterious modulations emanating from a group of stars. These signals could be extraterrestrial life hoping to alert others out in space of their existence, much in the way former reality show celebrities join Dancing With the Stars to let people know they still exist.
The study has found these very specific modulations coming from just 234 of 2.5 million stars surveyed. That means a tiny fraction of these stars are behaving in a strange, but similar manner. The search for an explanation of these signals led the paper's authors to conclude, well, aliens.
"We find that the detected signals have exactly the shape of an [extraterrestrial intelligence] signal predicted in the previous publication and are therefore in agreement with this hypothesis," say Ermanno Borra and Eric Trottier from Laval University in Canada, the paper's authors. "The fact that they are only found in a very small fraction of stars within a narrow spectral range centered near the spectral type of the sun is also in agreement with the ETI hypothesis."
