Signals probably from aliens – scientists

Author: Megan Ellis Updated: 08:30 27-10-2016

Two scientists have claimed in a research paper that unusual signals detected in space are probably from intelligent alien life.

The paper, accepted for publication in the Publications of the Astronomical Society of the Pacific , was written by Ermanno F. Borra and Eric Trottier from Laval University in Quebec, Canada.

The research used a Fourier transform analysis (which looks at the frequencies within a signal) of 2.5 million spectra, which identified "periodic spectral modulations" (signals) which can't be explained by the usual methods.

The paper's scientists have said that signals with the same period in the F2 to K1 range were found in 234 stars – and that these signals "cannot be caused by instrumental or data analysis effects".

So what is their explanation for the signals?

Well, one of the scientists – Borra – has previously written a paper on the possibility that aliens are sending us signals to make us aware of their existence.

This new paper therefore considers the same possibility.

"We considered the possibility that the signals are caused by intensity pulses generated by Extraterrestrial Intelligence (ETI), as suggested by Borra (2012), to make us aware of their existence. The shape of the detected signals has exactly the shape predicted by Borra (2012). The ETI hypothesis is strengthened by the fact that the signals are found in stars having spectral types within a narrow spectral range centered near the G2 spectral type of the sun," the scientists said.

Trottier and Borra ruled out other possibilities for the signals, such as rotational transitions in molecules.

While the scientists say that aliens are the most likely explanation for these signals, they confirm that their hypothesis would need to be confirmed by more work.

"The objects…should also be observed with large telescopes to obtain spectra with high resolutions and high signal to noise ratios that would allow studying the signals in greater details to definitely confirm that they are not data reduction or instrumental effects," they said.
