1966: National Medal of Science At the end of a star’s life, if its remaining mass is greater than 1.4 times our sun’s mass, then its ultimate fate will be rather strange. In 1930, Subrahmanyan Chandrasekhar, then 19, developed calculations to show that stars more than 1.4 times the mass of the sun disappear in massive explosions called supernovas. He is popularly known as the "birdman of India". Subrahmanyan Chandrasekhar worked on the origins and structures of stars, earning an important place in the world of science.
