Hot Topic Solar System Saturn Enceladus
Fueling Hot Jets
Topic: Enceladus
Summary: 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
Topic: Enceladus
Summary: 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.

Rubbing Tiger Stripes
Topic: Enceladus
Summary: New research suggests that the water plumes seen on Enceladus may not require the presence of liquid water near the moon's surface. However the moon may harbor a liquid ocean deep below its icy crust.

A Hot Start on Enceladus
Topic: Enceladus
Summary: Deep inside Saturn's moon Enceladus may be an organic brew, a heat source, and liquid water -- all the key ingredients for life. But where does the heat come from on a small body made of rock and ice? A new model suggests radioactive elements within Enceladus may have jump-started the heating of the moon's interior.

The Cosmic Graffiti Artist
Topic: Enceladus
Summary: Astronomers have found that Saturn's moon Enceladus is pelting some of the planet's other moons with ice particles sprayed from geysers at its surface.

Astrobiology Top 10: Water on Enceladus?
Topic: Enceladus
Summary: Astrobiology Magazine is looking back over 2006, highlighting the Top 10 astrobiology stories of the year. At number 3 is the discovery of what may be a reservoir of liquid water on Saturn´s icy moon, Enceladus. If true, it would broaden the diversity of solar system environments where there are conditions suitable for life. (This article originally appeared on March 10, 2006.)

Cracking Enceladus
Topic: Enceladus
Summary: Last year, the Cassini spacecraft discovered plumes of gas, water vapor and ice particles erupting from Saturn's moon Enceladus. At first, scientists thought it might indicate liquid water below the icy moon's surface, but now researchers have proposed an alternative model.

Enceladus Exudes an Air of Mystery
Topic: Enceladus
Summary: Atomic oxygen could never be confused with expensive perfume. But just as a fragrance lingering in the air of an empty room offers hints about a previous occupant, the cloud of oxygen the Cassini spacecraft encountered as it first approached Saturn turned out to be a calling card from another celestial presence.

Enceladus Rolled Over
Topic: Enceladus
Summary: Saturn's moon Enceladus - an active, icy world with an unusually warm south pole - may have performed an unusual trick for a planetary body. New research shows Enceladus rolled over, literally, explaining why the moon's hottest spot is at the south pole.

Liquid Water on Enceladus?
Topic: Enceladus
Summary: Could Saturn´s tiny moon Enceladus have liquid water right below the icy surface? A new paper in the journal Science argues for the presence of such a reservoir, saying it is the most likely source for the plumes of particles ejected from the moon´s south pole.
