Very often astronomers peer into distant galaxies to better understand how the universe works and even our own Solar system. But one of the great and distant galaxies has interested scientists for a different reason: her signal came that we were able to register here on Earth. One powerful and fast radio signal heard by the radar in Australia, and did not recur. Who would you send it?
Fast radio bursts: who sends them?
Galaxy with a complex scientific name DES J214425.25-405400.81 is 4 billion light years from us (a billion times farther than from the Sun to the nearest star). A light year is the distance that a beam of light can be overcome in a year. That is, light or radio signal from the galaxy will reach us in 4 billion years. It is from this galaxy came the signal — “quick burst“as they are called in the scientific world. They are so powerful that with one quick burst in the space is ejected by the energy that our Sun can throw for 10,000 years.
Fast radio bursts are included in the number of phenomena that science can not yet explain.
After receiving the message, the astronomers began to search for where he came from. They managed not only to detect the galaxy, which became the source of the signal, but to narrow it down to a particular place in the galaxy, 13,000 light years from the galactic center. But what is more important: how was the signal?
According to the researchers, it is possible that this “message” has spawned one of the most powerful cosmic phenomena: the destruction of a star or a black hole that sucked the star and ripped it apart. Of course, it could be the message of the aliens, but at the moment scientists refuse to believe it. They believe that the Universe is plenty powerful and unusual events that can send us a message like that.
Quick radio register more and more often: last year there was already over twenty. Their main feature is that they generally are not repeated. But if any signal again — be sure telescopes around the world will be directed to one point of the sky. Because to send a repeating signal may something reasonable.
