Repeat signals from deep space could be alien messages, study claims

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.

The center of the Milky Way is too violent for advanced life. Galaxies have habital zones too and anything more advanced then us would be further out. Not in.

That's hard because we are on the furthest end of the furthest spiral arm of the galaxy.   is there anything further out without going to the next galaxy?

We are in the middle on a smaller spiral arm.

Huh, when I look at the "we are here" maps it shows our sun near the end of the furthest spiral arm.    Where can I find an accurate map?

Google it. We are in the Local Arm right below the Perseus Arm. The Quora thingy isn't accurate.

Thanks.  I will look when I am not juggling.

you say this as if it's true...they may be so advanced/ technically far beyond anything we can imagine that they adapted to this violent environment years ago-- you've no idea what's out there, i don't that's for sure

Possibly they can adapt better if they are very advanced but how would such an advanced civilization develop in the first place in a violent place with frequent events, such as radiation bursts and asteroids, that are lethal to life.

They slipped in there later to hide. O_o
