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

A first of its kind measurement of a magnetar may have captured empty space behaving in a way physicists have predicted for 90 years, but never directly observed. The results published Wednesday in Nature. Fast facts Scientists using NASA’s IXPE (Imaging X-ray Polarimetry Explore
