Scientists for first time observe Optical polarisation phenomenon of fast spinning star
Scientists for first time have observed Optical polarisation phenomenon (polarised light emitted by rapidly rotating stars) after it was predicted by Indian astrophysicist and Nobel laureate Subrahmanyan Chandrasekhar 70 years ago. Optical polarisation phenomenon is a measure of the orientation of the oscillations of a light beam to its direction of travel. Key Facts The ..
