Laser Insight into Gas Giants
Using a high-energy laser, scientists are learning about the evolution and internal structure of gas giant planets. The research will yield information about planets like Jupiter and Saturn as well as distant extrasolar worlds.

Rings Made in the Shade
Scientists may have solved a long-standing mystery about anomalies in Jupiter's rings. The finding provides new information about the Jovian system and may yield clues about planetary formation.

The Extraordinary Ecosystems of Enceladus
Scientists discuss whether or not microbial life could survive inside Saturn's moon Enceladus. Based on observations of microbes on Earth that can live in environments absent of sunlight and oxygen, the researchers have outlined potential scenarios for how life might exist on the unique moon.

Organic Brew on Enceladus
Cassini has discovered that plumes from Saturn's moon Enceladus are 'hot' and brimming with water vapor and organic chemicals. The surprising discovery has important implications in the search for habitable environments in the Solar System.

A Brief Enceladus Shower
Earlier this month, NASA's Cassini spacecraft made a daring flight through the icy water jets of Enceladus. The data gathered might tell us if the moon harbors a water ocean or organics beneath its surface.

The Enceladus Enigma
Plumes of water and dust that spout from the south pole of Saturn's moon Enceladus have intrigued scientists ever since the Cassini spacecraft first captured images of the phenomenon. Now, new information may help scientists determine how the massive geysers are formed.

Studying Saturn's Ecology
With data from Cassini, scientists are beginning to understand the interactions between Saturn’s many dynamic moons. The environment of Saturn’s moons is important in determining whether or not some of them could be abodes for life, and how transport of material between the moons affects the development of important organic molecules.

Plumbing Enceladus
Scientists are beginning to understand the source of the giant geysers on Saturn's moon Enceladus. A new theory points to the potential existence of a liquid reservoir or lake just beneath the moon's surface.

Fueling Hot Jets
New data from NASA's Cassini spacecraft provides conclusive evidence that jets of icy particles spraying from Enceladus originate from hot spots on fractures that straddle the moon's south polar region. Enceladus caused a stir in 2005 when the jets were first found and scientists thought they might indicate liquid water beneath the moon's surface.

Enceladus Cold Case
A new model of Saturn’s icy moon Enceladus may indicate that liquid water is not present on the moon, quelling hopes of finding life there.
