The pH scale is a measure of how acidic or alkaline something is, 1 being highly acidic, 14 being highly alkaline, and 7 ...

Notably, hydrogen could serve as a potential energy source for microbial life — much like it does at Earth’s hydrothermal ...

An image of Saturn's moon Enceladus taken by NASA's Cassini spacecraft. (Image credit: NASA/JPL-Caltech) The discovery has implications beyond Enceladus' corner in the solar system.

Scientists have long viewed Saturn’s moon Enceladus, which harbors an ocean beneath its thick, icy shell, as one of the best places to search for life beyond Earth.. Now, a new analysis of data ...

Saturn's E-Ring, as imaged here by Cassini, is created by it's frozen Moon, Enceladus, ejecting icy... [+] material over time. Enceladus is the bright spot at the image's center.

Saturn's moon Enceladus has an even better chance of supporting extraterrestrial life than previously thought: researchers have discovered its oceans are more complex than first believed.

Enceladus is too far from the sun for life to employ photosynthesis, but the chemical energy released by geothermal activity could help fuel any hypothetical microbes in the moon’s ocean.

Chalk up one more feat for Saturn’s intriguing moon Enceladus. The small, dynamic moon spews out dramatic plumes of water vapor and ice — first seen by NASA’s Cassini spacecraft in 2005.

The possibility that Saturn's moon Enceladus could support life has strengthened after researchers determined its ocean is likely 1 billion years old, placing it in the sweet spot.

Saturn’s moon Enceladus drifts before the rings and the tiny moon Pandora in this view that NASA’s Cassini spacecraft captured on November 1, 2009.

Saturn is orbited by 146 moons, with Enceladus being the sixth largest at approximately 500km in diameter. This small, icy moon is characterized by its highly reflective white surface and geyser ...

Steady geysers of water ice on one of Saturn's icy moons appear to erupt more strongly when the moon is farthest from its ringed parent planet, scientists say. The warm vents at the south pole of ...
