Enceladus, a small icy moon of Saturn, is one of the most remarkable bodies in the solar system.

The Importance of Plumes

The Hubble Space Telescope is famous for finding black holes. It can pick out thousands of galaxies in a patch of sky the size of a thumbprint. The most powerful space telescope ever built, the Hubble provided evidence that the Universe is slowing down in its infinite rush into whatever lies beyond.

NASA's Cassini spacecraft and Deep Space Network have uncovered evidence Saturn's moon Enceladus harbors a large underground ocean of liquid water, furthering scientific interest in the moon as a potential home to extraterrestrial microbes.

We constructed a 6-degrees of freedom rotational model of Titan as a 3-layer body consisting of a rigid core, a fluid global ocean, and a floating ice shell.

Water Vapor Discovered At Ceres

ESA's Herschel space observatory has discovered water vapour around Ceres, the first unambiguous detection of water vapour around an object in the asteroid belt.

The hydrostatic equilibrium of multi-layer bodies lacks a satisfactory theoretical treatment despite its wide range of applicability.

In November and December 2012 the Hubble Space Telescope maged Europa's ultraviolet emissions in the search for vapor plume activity.

Europa Beckons

In light of today's announcement that Europa is likely spouting its vaporized ocean water into space, The Planetary Society calls on the White House and Congress to approve a new mission to explore this enigmatic moon of Jupiter to better understand its potential to support life.

A new analysis of data from Galileo has revealed clay-type minerals at the surface Europa that appear to have been delivered by a spectacular collision with an asteroid or comet.

Hubble has observed water vapor above the frigid south polar region of Jupiter's moon Europa, providing the first strong evidence of water plumes erupting off the moon's surface.
