Astronomers looking for signs of alien life are listening out for radio pulses originating from the center of the Milky Way.
If there is someone out there trying to communicate with us we have yet to pick up their signals (as far as we know), but now a recent study published in The Astronomical Journal
has outlined a novel new strategy designed to detect what could be messages sent by intelligent extraterrestrials.
Headed up by Cornell University graduate student Akshay Suresh, the researchers have developed new software designed to pick up repeated radio pulses coming from the depths of our galaxy and to determine whether they are naturally occurring pulsars or potential alien signals.
"Until now, radio SETI has primarily dedicated its efforts to the search for continuous signals," said study co-author Vishal Gajjar of the SETI Institute.
"Our study sheds light on the remarkable energy efficiency of a train of pulses as a means of interstellar communication across vast distances. Notably, this study marks the first-ever comprehensive endeavor to conduct in-depth searches for these signals."
The research, which uses data from the Green Bank Telescope in West Virginia, has targeted the center of our own galaxy because this region is particularly dense with stars and planets that could support life.
It may also be easier for a civilization in this area to send out signals towards the rest of the galaxy due to its central location.
It will be interesting to see what, if anything, the team discovers.
