WebApr 2, 2024 · Now a team of astronomers has found that the polarisation of the light, or the orientation of its wave, varies as the two stars orbit. Light that travels directly is unpolarised, oscillating along multiple planes at once. When it's reflected off a nonmetallic surface, the light becomes polarised, and oscillates along just one plane. http://www.astronomy.com/news/2024/02/how-do-stars-create-and-release-their-energy
