There has yet been no greater visual survey of a planetary system in the outer solar system than Cassini's imaging of the bodies in the Saturn environment. The enchanting beauty and visual clarity of our images have earned the attention and admiration of people all over the world, and our scientific discoveries, some of them quite startling, have revolutionized our understanding of everything Saturnian.|
We have collected here in the Newsroom the official announcements we have press released over the course of our travels through the Jupiter system and then on to, and in orbit around, Saturn. These bulletins serve as a chronological record of our `best hits'... those major scientific revelations that Cassini Imaging Team members made, often with colleagues, studying all those wondrous images they so meticulously planned.
Our major findings include determining the source of Saturn’s electrostatic discharges discovered decades earlier by Voyager; the 2005 discovery of the geysers of Enceladus, the 2006 inference thereby of a liquid water source beneath the moon’s surface, and the 2014 association of individual geysers with thermal hot spots and the conclusion that the geysers are producing the heat and not vice versa; new moons in orbit around Saturn; the first discovery in nature of free unstable normal modes and substantial wave amplification in any cosmic disk system, from Saturn's rings to the spiral galaxies; first sighting of a lake on Titan; solving the mystery of the piebald-like surface of Iapetus; and much, much more. These major announcements can be found under Press Releases.
Other public releases highlighting noteworthy images and special events, like moon flybys or `The Day the Earth Smiled', can be found under Special Events. (For in-depth scientific discussion, visit our Science page and check out our scientific publications, abstracts, and IAU circulars, as well as our 2018 `Cassini Mission Science Report: Imaging Science Subsystem' which itemizes almost all our discoveries at Jupiter and Saturn.)
We have also posted here the remarkably detailed, blow-by-blow Looking Ahead features that we released to the public, written by team associate Jason Perry, to allow anyone interested to follow the trajectory of Cassini and anticipate what scientific observations were up and coming in the next orbit around Saturn. It makes for a thrilling adventure story, even in hindsight.
Finally, we have also included here the results of a Cassini imaging contest we at CICLOPS ran in 2008 … great fun for us and for the participants as well.
