Astronomers find signature of magnetar outbursts in nearby galaxies
Apart from black holes, magnetars may be the most extreme stars in the universe. With a diameter less than the length of Manhattan, they pack more mass than that of our sun, wield the largest magnetic field of any known object—more than 10 trillion times stronger than a refrigerator magnet—and spin on their axes every few seconds.
