The alien life has been hard to find so far, but two scientists, E.F. Borra and E. Trottier, say that it could be a possible cause behind some unusual signals they observed.
In their recently submitted study, the astronomers from Canada's Laval University have documented their identification of 234 stars out of 2.5 million which seem to pulse light at a consistent rate.
The paper discounts possible interference from the instruments or data analysis and doubts that the signals were created by molecules, rapid pulsations, or Fourier transform of spectral lines.
As such, the team proposes the idea that, based on findings from previous research, there's a possibility that "the signals are caused by light pulses generated by Extraterrestrial Intelligence to makes us aware of their existence."
The study also notes that this small group was "overwhelmingly in the F2 to K1 spectral range."
As Universe Today points out, "That's significant because this is a small range centered around the spectrum of our own Sun. And our own Sun is the only one we know of that has an intelligent species living near it."
Despite the indications, there's certainly quite a bit of skepticism concerning the possibility of aliens behind these signals and the team states that "this hypothesis needs to be confirmed with further work."

In this combo photo, the head of New Zealandâs Mount John Observatory said on Jan. 2, 1979, that the unidentified flying objects filmed by Australian TV men were almost certainly the Planet Venus. Photo at left is from the TV film made over the weekend off the coast of New Zealand. Photo at right is of the Planet Venus made in 1974 by the Mariner space probe. New Zealand astronomer David Mabin said Venus is currently at its brightest and can be seen for about 12 hours a day. Another expert said the radar echoes reported were probably âRadar Angelsâ which are common in the Southern Hemisphere at this time of year. (AP Photo)

Michael Savage, 15-year-old son of prominent San Bernardino physician and surgeon, was practicing picture-taking with his new camera, when he saw motion out of the corner of his eye Thursday, July 24, 1956, San Bernardino, CA. He quickly shot this picture, tried to shoot another and in his haste, over-cranked the camera, drawing a blank with his second shot. The object disappeared in 30 seconds, he said, not over the horizon but quickly out of sight in the sky. (AP Photo/Michael Savage)

This photo is from the Air Force's "The Roswell Report," released Tuesday, June 24, 1997, which discusses the UFO incident in Roswell, N.M. in 1947. On balloon flights, test dummies were used and placed in insulation bags to protect temperature sensitive equipment. These bags may have been described by at least one witness as "body bags" used to recover alien victims from the crash of a flying saucer. The 231-page report, released on the eve of the 50th anniversary of the Roswell, N.M., UFO incident, is meant to close to book on longstanding rumors that the Air Force recovered a flying saucer and extraterrestrial bodies near Roswell.

Described as a leisure home of the 1970s, this flying saucer-shaped house - called the 'Futuro' - is made up of 16 pre-moulded segments of fibreglass. Designed by Finnish architect Matti Suuronen, it is being made under license from Oy Polykem of Helsinki by a Lancashire firm (Waterside Plastics Ltd, of Todmorden) and is described as the leisure home of today and tomorrow.
