- 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.
- The phenomenon was observed using High Precision Polarimetric Instrument (HIPPI), world’s most sensitive astronomical polarimeter to detect polarised light from Regulus, one of brightest stars in night sky about 79 light years away.
