Discovery galileo galilei found what came to be known as the galilean moons around december 1609 or january 1610 as a result of improvements he made to the telescope, galileo was able to see celestial bodies better than ever before in human history. From 1996 to 1999, the galileo spacecraft careered through the jovian system on a complex but carefully planned trajectory that provided repeated close encounters with the large galilean moons.
