On the auspicious occasion of Diwali, Google doodle celebrates the 107th birthday of legendary India-origin astrophysicist Subrahmanyan Chandrasekhar, who won the Nobel Prize for his theory of the evolution of stars.
Here are things to know about 'Starman of India':
Described as a 'child prodigy', Subrahmanyan Chandrasekhar was born in Lahore in 1910 to a Tamil family.
Chandrasekhar made his most significant discovery while working as a researcher at Cambridge University, which became known as the Chandrasekhar Limit, which was earlier discredited.
More than 30 years later, in 1966, scientific research with computers and the hydrogen bomb gave credit to Chandrasekhar's calculations.
At age of 73, Mr Chandrasekhar won a Nobel Prize for Physics in 1983 "for his theoretical studies of the physical processes of importance to the structure and evolution of the stars".
He is related to Sir CV Raman, who was his uncle and won the Nobel Prize in Physics in 1930.
