Astronomers and scientists at the Indian Institute of Astrophysics (IIA), along with their international collaborators, while studying the Omega Centauri, have found that hot stars and white dwarfs emitted less ultraviolet radiation than expected.

Omega Centauri

Omega Centauriis a globular cluster in the constellation of Centaurus that was first identified as a non-stellar object by Edmond Halley in 1677.
Located at a distance of 17,090 light-years(5,240 parsecs), it is the largest-known globular cluster in the Milky Way at a diameter of roughly 150 light-years.
It is estimated to contain approximately 10 million stars, and a total mass equivalent to 4 million solar masses, making it the most massive-known globular cluster in the Milky Way.
Omega Centauri is very different from most other galactic globular clusters to the extent that it is thought to have originated as the core remnant of a disrupted dwarf galaxy.
Omega Centauri is one of the few globular clusters visible to the naked eye—and appears almost as large as the full Moon when seen from a dark, rural area.
