Besides black holes, magnetars may be the most powerful celestial bodies in the Universe. They have a diameter
Magnetars are so highly magnetized that evensmall disturbances in the magnetic field can produce bursts of X-rays that last sporadically for weeks or months. These unusual stars are also thought to be the source of some types of gamma-ray bursts (GRBs): bright flashes of high-energy radiation.
Short gamma-ray burst detected on April 152020 in a galaxy 11.4 million light-years away could help astronomers find magnetic bursts more easily. This is necessary to explain the nature of magnetars and the features of their rays.
A giant flash, recorded as GRB 200415A, was detected by NASA detectors. They determined its possible location: all guesses intersected on the spiral galaxy NGC 253.
GRB beams are the most powerful in space and can bedetectable from a billion light years away. Most of them last less than two seconds, this is called a gamma-ray burst. It occurs when a pair of spinning neutron stars merge with each other.
