They detect mysterious radio signals and they do not come from our galaxy

Until now we have not received a signal like this: astronomers have detected bursts of radio waves coming from beyond the limits of the Milky Way.

Therapid radio explosions They had already been detected on other occasions during the last decade, but on no occasion with the properties of those detected by the Arecibo radio telescope in Puerto Rico and Cornell astronomers.

The FRB (for its acronym in English Fast Radio Bursts) have hitherto been taken as signals caused by isolated phenomena, such as supernova explosions or the collapse of a star in a black hole. The last bursts haveconsistent and repetitive properties.

Unknown and repetitive radio bursts

Not much is known about the FRBs detected so far, because they are radio signals that last milliseconds and have not been able to find exactly what causes them In the universe.

The Astronomer Paul Scholzfilterthe observations of theArecibo radio telescope and recently found that there were up to 10 radio bursts, repetitive bursts that came from a phenomenon that does not have to be explosive, but could be a rotating star of great power, since also the brightness and spectrum of the bursts were different from any other FRB previously detected.

The exact location of where they originate is unknown, but it is estimated that the signals came from a galaxy more than 6 billion light years away, therefore it would be the first time that they have heard from an unknown source beyond our galaxy.

All the details of the research have been published in the journal Nature.
