He knew how the stars will die | Chandrasekhar

Chandrasekhar became famous for his discoveries about the evolution of the stars. His work was vast, and he began early, developing his theory of stars’ evolution before he had even turned 20. Google is changing its logo globally to a doodle of him and the Chandrasekhar Limit. That refers to his calculation that once a star reaches 1.44 times the size of our own sun, it doesn’t form a white dwarf as expected but collapses, eventually becoming a black hole.
