This May Be an Evidence to Aliens, say Scientists

December 16, 2016

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.

This image of NGC 2440 shows the colourful "last hurrah" of a star like our Sun. The star is ending its life by casting off its outer layers of gas, which formed a cocoon around the star's remaining core. Ultraviolet light from the dying star makes the material glow.

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.”

Huge waves are sculpted in this two-lobed nebula some 3000 light-years away in the constellation of Sagittarius. This warm planetary nebula harbours one of the hottest stars known and its powerful stellar winds generate waves 100 billion kilometres high. The waves are caused by supersonic shocks, formed when the local gas is compressed and heated in front of the rapidly expanding lobes. The atoms caught in the shock emit the spectacular radiation seen in this image.[Image courtesy of NASA]

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.”

Sparkling at the centre of this beautiful NASA/ESA Hubble Space Telescope image is a Wolf–Rayet star known as WR 31a, located about 30 000 light-years away in the constellation of Carina (The Keel). The distinctive blue bubble appearing to encircle WR 31a, and its uncatalogued stellar sidekick, is a Wolf–Rayet nebula — an interstellar cloud of dust, hydrogen, helium and other gases. Created when speedy stellar winds interact with the outer layers of hydrogen ejected by Wolf–Rayet stars, these nebulae are frequently ring-shaped or spherical. The bubble — estimated to have formed around 20 000 years ago — is expanding at a rate of around 220 000 kilometres per hour! Unfortunately, the lifecycle of a Wolf–Rayet star is only a few hundred thousand years — the blink of an eye in cosmic terms. Despite beginning life with a mass at least 20 times that of the Sun, Wolf–Rayet stars typically lose half their mass in less than 100 000 years. And WR 31a is no exception to this case. It will, therefore, eventually end its life as a spectacular supernova, and the stellar material expelled from its explosion will later nourish a new generation of stars and planets.[Image courtesy of NASA]

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.
