A Dead Star's X-rays May Have Just Confirmed a 90-Year-Old Prediction About Empty Space
NASA's IXPE spacecraft, paired with NICER and Australia's Murriyang radio telescope, caught magnetar 1E 1547.0-5408 emitting X-rays polarized up to ~80% — evidence that its trillion-times-Earth magnetic field bends empty space itself, as QED predicted in 1936.

A Faint X-Ray Flash Just Filled In the 'Missing Link' Between Ordinary Supernovae and Gamma-Ray Bursts
China's Einstein Probe caught a brief X-ray shock breakout from a dying Wolf-Rayet star that had all the makings of a gamma-ray burst but never fired one, giving astronomers just their second clean look at this elusive process in two decades.
