• "In this image, a highly-magnetized neutron star undergoes a "starquake", a violent seismic rearrangement of the neutron star's crust, creating a explosion of gamma-rays which can easily be seen from across the galaxy."
• "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."
