This artist’s view shows how the light coming from the surface of a strongly magnetic neutron star (left) becomes linearly polarized as it travels through the vacuum of space close to the star on its way to the observer on Earth (right). The polarization of the observed light in the extremely strong magnetic field suggests that the empty space around the neutron star is subject to a quantum effect known as vacuum birefringence. The magnetic and electric field directions of the light rays are shown by the red and blue lines. Image credit: L. Calçada / ESO.

Astronomers Report First Observational Evidence for Vacuum Birefringence
