Indian Astrophysicists Spot UV-bright Stars In NGC 2808

  • Scientists from the Indian Institute of Astrophysics (IIA) have spotted rare hot UV-bright stars in the massive globular cluster NGC 2808 of our Milky Way Galaxy.
  • UV-bright stars have been distinguished from the relatively cooler main-sequence stars using images from Ultraviolet Imaging Telescope (UVIT) onboard satellite AstroSat- India’s first multi-wavelength space satellite.
  • NGC 2808 is said to have at least five generations of stars, which exist in the late stages of evolution of a Sun-like star.
  • Old globular clusters, referred to as dinosaurs of the Universe, help to understand how stars evolve through various phases between their birth and death.
