ASTROSATAstroSat’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 :-
