Fortunately, none of them is closer than SGR 1900+14, so your keys should still be right where you left them. 1 When a large star burns out, it explodes into a massive cloud of gas called a supernova. 2 The star's core condenses and if it spins fast enough, it generates a powerful magnetic field. 3 The field surrounds the star; its force can crack the surface, which explodes in a "starquake."

Astronomers expect more data soon, from less powerful starquake aftershocks on SGR 1900+14, and from the other three suspected active magnetars in the galactic neighborhood.
