NASA's IXPE Captures First Evidence of Vacuum Behavior Predicted 90 Years Ago
NASA's Imaging X-ray Polarimetry Explorer (IXPE) has achieved a potentially groundbreaking observation of a magnetar that may confirm a decades-old theoretical prediction about the behavior of empty space.
Scientists conducted more than 140 hours of observations of magnetar 1E 1547-5408 between March and April 2025.
