- The Astronomers and scientists at the Indian Institute of Astrophysics (IIA) have found that hot stars and white dwarfs emitted less ultraviolet radiation than expected.
- It is discovered while studying the Omega Centauri, which is the most massive globular cluster system in our galaxy.
- The enhancement in helium could be one of the reasons for the lesser far-ultraviolet radiation emitted by these stars.
- The team detected strange hot stars in the cluster using the Ultraviolet Imaging Telescope (UVIT) images on AstroSat.
- AstroSat is India’s first dedicated space observatory, which has been operating since 2015.
