Indian Astronomers have identified have identified a new population of ultraviolet stars in the globular cluster NGC 2808 using the Indian multi-wavelength space observatory AstroSat, launched in September 2015.

AstroSat: AstroSat is India’s dedicated multi-wavelength space observatory, it observes the universe in the optical, Ultraviolet, low and high energy X-ray regions of the electromagnetic spectrum.

NGC 2808: Globular clusters are collections of thousands to millions of stars, moving as one unit. These stars are tightly held together by the gravity of the cluster itself and are believed to have formed together at roughly the same time.  The globular cluster contains stars with a variety of masses but with similar chemical composition.

NGC 2808 is one of the massive globular clusters and is located at a distance of 47,000 light years from us.
