On this day in 1625 - June 8th - Italian-French astronomer Giovanni Domenico (Jean-Dominique) Cassini was born.

Cassini was one of the most important astronomers of the 17-18th centuries, and was the first of four Cassinis to be the director of the Paris Observatory. His study of Saturn, including discovering four of Saturn's moons, led to the NASA/ESA/ASI Cassini–Huygens mission bearing his name.
