ASTROSAT
AstroSat’s Ultraviolet Imaging Telescope spots rare ultravioletbright stars in a massive intriguing cosmic dinosaur in the Milky Way.
□ SIGNIFICANCE.
◇ Such UV-bright stars could be the reason for the ultraviolet radiation coming from old stellar systems such as elliptical galaxies which are devoid of young blue stars.
□ ABOUT :-
