Where’s it coming from?
The publication Science Alert writes that on April 28 the Observatory around the world detected a flare star at a distance of about 30 thousand light years from Earth. She flashed a single splash of bright radio waves with a duration of 0.1 seconds. Along with this astronomers “catch” a very bright x-ray counterpart of the burst.
This surge, according to most astronomers, was published in the milky Way Magnetar SGR 1935 + 2154. Magnetar is a neutron star, with its exceptionally strong magnetic field. As a rule, Magnetar in diameter consist of about 20-30 km, but most of the mass exceeds the mass of the Sun. The publication adds that the surge can help to learn more about one of the old cosmic mysteries — the emergence of fast radio bursts (FRB, Fast Radio Bursts).
National Geographic writes that the FRB is an extremely powerful radio signals from deep space at a distance of millions of light years from Earth. Some of these ways to radiate more energy than 500 million Suns. While they last fractions of a second, and most of them are not repeated — this makes them very difficult to predict, track, and understand.
FRB was first discovered in 2007. Among the hypotheses about their origin was and version alien nature of the signals. But perhaps now the source of their origin, finally announced Magnetar.
