S. Chandrasekhar's 107th Birthday

Looks like Google celebrated Subramanya Chandrasekhar's 107'th birthday with a doodle. I had missed it, so I got excited to go check it out again.

The doodle is amazing! It illustrates the concept of a star when it gains 1.4 times the mass of sun will turn into white-dwarf and eventually into a black-hole!

Chandrasekhar discovered this, and it is known as Chandrasekhar's limit.
