NASA’s IXPE Studies Magnetar

News - public release Created on 07 Aug 2026 National Aeronautics and Space Administration

Scientists using NASA’s IXPE (Imaging X-ray Polarimetry Explorer) conducted more than 140 hours of observations of the magnetar 1E 1547-5408, shown in this Aug. 5, 2026, artist’s concept, between March and April 2025. In doing so, they may have captured empty space behaving in a way physicists have predicted for 90 years, but never directly […]

This artist’s concept depicts magnetar 1E 1547.0-5408, a rapidly rotating neutron star with magnetic fields over a trillion times stronger than Earth’s. Blue curves emanating from the star's two magnetic poles represent the magnetic field lines. The magnetar is a significant emitter of radio and X-ray radiation, with their peaks offset during its 2.1-second rotation period. This indicates the primary X-ray emitter is a secondary “hot spot” offset from the magnetic axis. These emitters are depicted as conical sections: the lighter blue radio emission peaks at the magnetic field's symmetry axis, while the darker blue X-ray emission peaks below. NASA/Pablo Garcia

Scientists using NASA’s IXPE (Imaging X-ray Polarimetry Explorer) conducted more than 140 hours of observations of the magnetar 1E 1547-5408, shown in this Aug. 5, 2026, artist’s concept, between March and April 2025. In doing so, they may have captured empty space behaving in a way physicists have predicted for 90 years, but never directly observed.

Magnetars are a special class of neutron stars with ultra-strong magnetic fields, the strongest of any object in the observable universe, around a trillion times stronger than the strongest permanent magnets ever built on Earth.
