NASA's Cassini spacecraft has provided scientists the first clear evidence that Saturn's moon Enceladus exhibits signs of present-day hydrothermal activity which may resemble that seen in the deep oceans on Earth.

NASA will host a teleconference at 11 a.m. EDT on Thursday, March 12, to discuss Hubble Space Telescope's observations of Ganymede, Jupiter's largest moon. These results will help scientists in the search for habitable worlds beyond Earth.

The pH of Enceladus' Ocean

Observational data from the Cassini spacecraft are used to obtain a chemical model of ocean water on Enceladus.

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.
