Researchers Ermanno F. Borra and Eric Trottier have lifted the lid on the bizarre signals from distant stars being sent to Earth using a mathematical tool.
The duo claim our planet has received 234 alien signals – from 2.5 million readings detected by the Sloan Digital Sky Survey, an eight-foot diameter telescope in Sunspot, New Mexico.
It is believed if lifeforms from outer space flashed lasers, bursts of radiation would be spotted in the light coming from the host stars.
The pair, from Laval University in Quebec, have said the most likely explanation is aliens – after ruling out other alternatives.
“The fact that they are only found in a very small fraction of stars within a narrow spectral range centred near the spectral type of the sun is also in agreement with the ETI hypothesis.”
But not everyone is so sure.
The SETI Institute”s Breakthrough Listen project – backed by billionaires Yuri Milner and Mark Zuckerberg and famed physicist Stephen Hawking – said it was too early to say it”s the work of aliens.
“It is too early to unequivocally attribute these purported signals to the activities of extraterrestrial civilisations,” the statement said.
“Internationally agreed-upon protocols for searches for evidence of advanced life beyond Earth (SETI) require candidates to be confirmed by independent groups using their own telescopes, and for all natural explanations to be exhausted before invoking extraterrestrial agents as an explanation.”
But the project at UC Berkeley praised the research as “certainly worthy of additional study”.
This comes as Mr Hawking launched a dire warning in the hunt for life.
And earlier this year, space boffins discovered freak radio signals which were believed to be possibly signs of alien contact.
Russia were blasted for covering up the discovery for a whole year – but Vlad”s country denied hiding extraterrestrial lifeforms.
