English: Astronomers have discovered a possible magnetar SWIFT J195509+261406 that emitted 40 visible-light flashes before disappearing again. Magnetars are young neutron stars with an ultra-strong magnetic field a billion times stronger than that of the Earth. The twisting of magnetic field lines in magnetars give rise to starquakes, which will eventually lead to an intense soft gamma-ray burst. In the case of the SWIFT source, the optical flares that reached the Earth were probably due to ions ripped out from the surface of the magnetar and gyrating around the field lines.
Español: Astrónomos han descubierto un posible magnetar que emitió 40 destellos en luz visible antes de desaparecer otra vez. Los magnetares son estrellas de neutrones jóvenes con un campo magnético ultra-potente, un trillón de veces más poderoso que el de la Tierra. La torsión de las líneas de los campos magnéticos en magnetares ocasiona 'terremotos estrelares' que finalmente llevarán a un intenso estallido de rayos gamma suaves. En el caso de la fuente SWIFT, los destellos ópticos que alcanzaron la Tierra fueron probablemente causados por iones arrancados de la superficie del magnetar, girando alrededor de las líneas del campo.
