Enceladus is the sixth-largest moon of Saturn and the 18th-largest in the Solar System. It is about 500 kilometers (310 miles) in diameter, [5] about a tenth of that of Saturn's largest moon, Titan. It is mostly covered by fresh, clean ice, making it one of the most reflective bodies of the Solar System.
Icy moons warmed by tides may be the most common type of celestial body in the galaxy to have liquid water, [3] and thus the most likely type of object to possibly have water-based life. Some icy moons exhibit cryovolcanism, as well as geysers. The best studied example is Saturn's Enceladus.
Over the course of its mission, Cassini discovered geyser-like water plumes erupting through the icy shell of Saturn’s moon Enceladus, long thought to be a potential place in the Solar System ...
The discovery was based on data collected by NASA's Cassini spacecraft, the first to orbit Saturn, during its 13-year landmark exploration of the gaseous giant planet, its rings and its moons from ...
An annotated picture of Saturn's many moons captured by the Cassini spacecraft. Shown in the image are Dione, Enceladus, Epimetheus, Prometheus, Mimas, Rhea, Janus, Tethys and Titan. The moons of Saturn are numerous and diverse, ranging from tiny moonlets only tens of meters across to the enormous Titan, which is larger than the planet Mercury.
Enceladus used to be just another icy moon until the Cassini spacecraft spotted geysers on its surface, spewing water 125 miles into the sky back in 2005. Now, after years of research, scientists ...
The Cassini mission, run by Nasa and other space agencies, already found cracks on the south pole of Enceladus, a moon around Saturn. Plumes containing gas and ice grains spew out of those cracks ...
Dione (/ d aɪ ˈ oʊ n i /), also designated Saturn IV, is the fourth-largest moon of Saturn.With a mean diameter of 1,123 km and a density of about 1.48 g/cm 3, Dione is composed of an icy mantle and crust overlying a silicate rocky core, with rock and water ice roughly equal in mass.
