Google is commemorating 17th century astrologer, astronomer and mathematician Johanes Kepler's 442nd birthday with its latest doodle.
Kepler was born on 27 December 1771 and took to astronomy after working as a maths teacher in Austria where he became an associate of Prince Hans Ulrich von Eggenberg.
According to the Independent, he became an assistant to astronomer Tyro Brahe and later the imperial mathematician to Emperor Rudolf II.
Kepler is best known for his laws describing the motion of planets around the sun, which he published between 1609 and 1619.
He passed away at the age of 58 on 15 November 1630.
