Astronomers have received a mysterious radio signal from a distant galaxy
Very often, astronomers peer into distant galaxies to better understand how the universe and even our own solar system. But one of the large and distant galaxies has interested scientists for another reason: it came from the signal that we were able to register here on Earth. A powerful and fast signal is heard radar in Australia, and will not be repeated. Who could it send?
Fast radio bursts, Who sends them?
Galaxy with a complex scientific name DES J214425.25-405400.81 located 4 billion light-years away (a billion times more than from the Sun to the nearest star). Light year - the distance that a beam of light can be overcome for the year. That is, light or radio signal from the galaxy come to us for 4 billion years. It is because of this galaxy signal came - "fast radio burst," as they are known in the scientific world. They are so powerful that a single fast radio bursts ejected into space the energy that our sun can throw for 10 000 years.
Fast radio bursts are among the phenomena that science can not explain. Upon receiving the signal, astronomers began to look for, where he came from. They managed not only to detect the galaxy, which became the source of the signal, but also narrow a search to a specific location in the galaxy - 13 000 light-years from the galactic center. But what is important: how did this signal?
According to scientists, it is quite possible that this "message" has created one of the most powerful cosmic phenomena: the destruction of a star or a black hole that sucked the star and tore it to pieces. Of course, this may be the message the aliens, but at the moment the scientists refuse to believe it. They believe that the universe plenty of powerful and unusual events that could send us such a message.
Fast signals are recorded more often: there were more than twenty in the past year. Their main feature is that they are usually not repeated. But if at least some signal again - be sure telescopes all over the world will be directed to one point of the sky. Because send a repeating signal can and something reasonable.
