SETI investigating mysterious, extraterrestrial signal from deep space star system

The Search for Extraterrestrial Intelligence (SETI) program has spent decades scanning the heavens looking for potentially alien signals — and it sounds they just picked one up.

An international team of scientists are reportedly investigating a mysterious signal spike from a 6.3-billion-year-old star located 95 light-years away from Earth in the Hercules constellation. Scientists believe there is at least one planet orbiting the star. The signal was received on May 15, 2015, at a wavelength of 2.7 cm. The estimated amplitude of the signal is 750 mJy. Word is getting out now because SETI researchers quietly spread word that the signal warranted further investigation.

Obviously, it’s way too early to even imply there could be an advanced alien civilization out there sending signals our way. But there could be. The signal is high-frequency, which is rare to occur naturally, though the team is now working to figure out whether the readings could be the result of ground interference or noise. If it is aliens, researchers say a signal of this type and strength could’ve been generated by a civilization at the Kardashev Type II level. The Kardashev scale is used to measure a civilization’s advancement, and Type II is capable of harnessing the power of a star, i.e. a Dyson sphere.

Put simply: If all of that pans out (which is a long, long shot), this potential alien race could be way more advanced than us. So, yay?

For now, SETI is putting more resources on the project to keep a closer eye on the system to see what else they might be able to pick up. It’s still early, and odds are ultimately against it being a race of ultra-advanced aliens.

But c’mon.
