SWIFT J195509+261406 magnetar, optical image
SWIFT J195509+261406 magnetar. Images showing the possible magnetar SWIFT J195509+261406 over a time span of around 30 minutes, during which the source brightens quickly then fades away. This object showed intense flaring, emitting 40 visible-light flashes over a 3 day period 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 (white lines) in magnetars give rise to 'starquakes', which will eventually lead to an intense soft gamma-ray burst. It is thought that 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. Imaged by the IAC80 telescope at Teide Observatory, Spain.
