Aliens may be sending strange messages from the stars, scientists says. They believe that the unusual messages they took from deep space might have come from aliens.

Scientists from Cornell University have recently released a report claiming that they acquired encouraging signals from stars. The report points that the signals could be coming from extraterrestrial intelligence that is aiming to alert us to their existence. Scientists E.F. Borra and E. Trottier from Laval University in Quebec also reports that they found disturbances in the fractions in stars far, far away.

A message from Aliens?

"A Fourier transform analysis of 2.5 million spectra in the Sloan Digital Sky Survey was carried out to detect periodic spectral modulations. Signals having the same period were found in only 234 stars overwhelmingly in the F2 to K1 spectral range. The signals cannot be caused by instrumental or data analysis effects because they are present in only a very small fraction of stars within a narrow spectral range and because the signal to noise ratio considerations predict that the signal should mostly be detected in the brightest objects, while this is not the case."

Scientists Borra and Trottier believe that the messages are probably coming from being from the outer rims. The report 'Discovery of Peculiar Periodic Spectral Modulations in a Small Fraction of Solar-Type Stars' says;

"We consider several possibilities, such as rotational transitions in molecules, rapid pulsations, Fourier transform of spectral lines and signals generated by Extraterrestrial Intelligence (ETI). They cannot be generated by molecules or rapid pulsations. It is highly unlikely that they come from the Fourier transform of spectral lines because too many strong lines located at nearly periodic frequencies are needed. Finally, we consider the possibility, predicted in a previously published paper, that the signals are caused by light pulses generated by Extraterrestrial Intelligence to makes us aware of their existence."

According to scientists, the signals do match with some previous reports about extraterrestrial intelligence possibility, hence in agreement with a cumulative hypothesis. Surely they both are clear that the claim needs further researches and work to confirm.

"We find that the detected signals have exactly the shape of an ETI signal predicted in the previous publication and are therefore in agreement with this hypothesis. 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. However, at this stage, this hypothesis needs to be confirmed with further work. Although unlikely, there is also a possibility that the signals are due to highly peculiar chemical compositions in a small fraction of galactic halo stars."

The research might be illuminating a hundred years old mystery that has been one of the main subjects of science fiction scene. And even if they need time to prove their idea, it is already a big success and such an exciting phase for science field either.
