The astronomers record signals regularly coming from far space. They reach the Earth every 157 days. Science cannot explain these strange and mysterious signals, and the attempts are being made to do so. A group of astronomers calls that signal a fast radio flash - FRB. Mysterious "messages" are energy flashes that last no more than a millisecond, representing a wave. They are repeated with an enviable frequency - exactly every 157 days.
The signal was given the name FRB-121102. It flares up for ninety days, and then fades out for exactly sixty-seven days. That glow was first seen in 2007. Since that time, the scientists have suggested many different ideas and hypotheses related to the occurrence of outbreaks, but none of them could explain the origin of the mysterious impulses.
To date, they have recorded more than a hundred. About a month ago, a group of astronomers recorded another outbreak, calling it the most powerful in the entire history of observations. It was so intense that the scientists suggested an outbreak in another galaxy.
And in January of that year, the researchers from the Cornell University suggested that the source of outbreaks could be magnetars. Charged by neutron stars and spinning around their axis, they create a process of motion called precession.
The scientists suggest that flares can create just such magnetars. Another hypothesis is associated with a neutron star that rotates around a neighbor in a binary system, causing modulation at the peak of activity.
Kaustubh Rajwad, a leading specialist from the University of Manchester, believes that none of the hypotheses has a clear explanation. Impulses continue to be a mystery to astronomers. To discover their secret, further observations are needed. They may take decades, but will help to find out the source and origin.
