US scientists from Cornell University have begun searching for possible alien signals in our galaxy. The galactic center of the Milky Way, the region around the supermassive black hole Sagittarius A, was chosen as the location for such a study, Science Alert reports. “Sagittarius A” is one of the best places in the Milky Way to send broad, repetitive radio signals to anyone who listens,” the scientists say. A group of scientists led by astronomer Akshay Suresh from Cornell University created the BLIPSS project (Breakthrough Listen Investigation for Periodic Spectral Signals), which is designed to search for and amplify strange pulsed radio emissions from the Milky Way’s galactic center that may be from “extraterrestrial intelligent organisms.” An alien radio beacon similar to a pulsar.

Also, according to the scientists, there are natural objects there that send out repeating radio signals. These signals can ‘point’ in the direction where a habitable exoplanet could potentially be located. “If we’re going to find an alien signal, this (Sagittarius A – ed.) is one of the best places to look, but not without challenges. Extracting an artificial signal from the natural “cacophony of light” emanating from the galactic center is quite a monumental task,” the scientists say. Previously, scientists used BLIPSS to find pulsars that emit periodic pulses of light. The researchers tested their software on pulsars , to make sure it could detect the types of signals they were looking for. To do this, the scientists narrowed the frequency range down to less than a tenth of the range occupied by an FM radio station, with pulse intervals between 11 and 100 seconds. Then the scientists found no signals that would fit the search parameters, but the effort demonstrated the effectiveness of their methods. “Our study sheds light on the surprising energy efficiency of pulse trains as a means of interstellar communication over vast distances. It is noteworthy that this study marks the first comprehensive attempt in history to conduct an in-depth search for these (alien – ed.) signals,” the scientists emphasize. We will remind, scientists suggest that the Milky Way galaxy may have a different shape than previously thought.
