Google's latest doodle is an animated one to commemorate the 540th birthday of Nicolaus Copernicus, a Polish astronomer. He was the one who formulated a comprehensive heliocentric model of solar system describing that the sun is at the center of the universe and not the Earth.
The animated doodle shows the sun placed at the centre of the universe and the moon revolving around the Earth. It also shows five other planets including Mercury, Venus, Mars, Jupiter and Saturn apart from Earth, all revolving around the sun. The letters in the Google logo appears in the backgound of the universe with the second 'O' being the sun.

Born on February 19, 1473 in the city of Thorn in Royal Prussia, Nicolaus Copernicus was a Renaissance mathematician and astronomer. By 1514, at the behest of the Catholic church, he was involved in working to improve the calendar. In 1530, Copernicus produced a major piece of research, De Revolutionibus Orbium Coelestium (On the Revolutions of the Celestial Spheres).
He passed away on May 24, 1543. Legend has it that the first printed copy of De Revolutionibus was placed in his hands on the day of his death. The Polish astronomer was reburied in Poland in a lavish ceremony 467 years after his death, when his long lost skeleton was found in the altar of Frombork Cathedral in northern Poland, where he originally was buried in 1543.
