Researchers have recently detected six more blasts of radio signals originating from a place in deep space outside our galaxy from where similar signs were distinguished earlier this year as well as in 2012. 17 particular radio signs have been detected from this area in space, and scientists say this could be us being hailed by extraterrestrials.
The Green Bank Telescope in the US and the Arecibo Observatory in Puerto Rico detected the signals. And the observations are written in an article published in the Astrophysical Journal
. The experts described the signals as Fast Radio Bursts (FRBs). FRBs were first observed in 2007. These quick radio signals last for just a couple of milliseconds, and can be only be recognized using very sensitive radio arrays.
FRBs are special because although they only exist for an extremely short period of time, they can emit an amount of energy equal to what the sun produces for a whole day. As of now, the 17 signals have been recognized from a similar area in the deep space far past our solar system. Experts' theorize that they could be extraterrestrial in origin.
"We report on radio and X-ray observations of the only known repeating fast radio burst source, FRB 121102," the team wrote in The Astrophysical Journal
"We have detected six additional radio bursts from this source: five with the Green Bank Telescope at 2 GHz, and one at 1.4 GHz with the Arecibo Observatory, for a total of 17 bursts from this source."
If these signals really mean that extraterrestrials are trying to reach out to us, should we feel scared or excited?
