Conference Details:

International Conference on the occasion of the 375th birthday of Christiaan Huygens, (born 14 April 1629) In the 17th century, Christiaan Huygens was one of the most respected leading European scientists. He was the first to be what we would today call “scientific director” of the Académie Française. A highlight in his career was the discovery of Saturn’s largest moon, Titan, in 1655


This conference will start with a tribute to Christiaan Huygens, his contributions and interactions in the 17th century followed by recent results of observations of Saturn/Titan from ground and space, an overview of the Cassini/Huygens mission. The conference will end with a public outreach day aimed at the amateur astronomy community that will have the opportunity to present, in the forms of posters or exhibits, their latest observations of Saturn and Titan.
