The astronomers analyzed the light signals from 2.5 million stars observed by the Sloan Digital Sky Survey. The team of researchers discovered strange lights coming from 234 stars. They suggested that the bright pulses have the exact form of a signal produced by an extraterrestrial intelligent life form. Stephen Hawking's team, who is investigating the possibility of extraterrestrial life, took the case in order to confirm or deny it, according to descopera.ro and sciencealert.com.

Are these light signals emitted by alien civilizations?

Ermanno Borra and Eric Trottier, astronomers from the University of Laval in Canada, argue that there are 234 alien civilizations who are emitting coordinated light signals toward the Earth, but the information is extremely premature. The researchers from the Breakthrought Listen project, founded by Yuri Milner and Stephen Hawking said that aliens are the last thing they research when investigating such allegations.

Researchers from SETI Research Center said that one of the 10,000 objects with unusual light observed by Borra and Trottier deserves to be studied further. They added that extraordinary claims need to be supported by extraordinary evidence. They think that it's premature to declare that the lights are produced by extraterrestrial civilizations.

Here's what Borra and Trottier have found

In 2012, Borra suggested that if extraterrestrial civilizations wanted to contact people they would send rays of light which would look unnatural for researchers to know that they have to be examined. He teamed with Trottier to analyze more than 2.5 million stars that were recorded by the Sloan Digital Sky Survey, to notice if one of them would emit such light.

The team said they detected the same type of signal when they analyzed 234 of the stars.

The researchers said they have discovered that the light signal had the exact form produced by the of extraterrestrial life forms. The team have established a scale from 0 to 10 to quantify the discovery of the existence of life on other planets. So far, the score is between 0 and 1, but the analysis will continue.
