NASA Marshall(@NASA_Marshall):Using our IXPE telescope, scientists found strong evidence that supports a 90-year-old quantum theory! While observing a magnetar, the measurements showed a higher-than-expected level of polarization - pointing to an effect known as vacuum birefringence: https://t.co/8nE5ilru2e
