Analysis indicates Enceladus’ sub-surface ocean may be habitable.
Enceladus orbits 180,000 km (111,847 miles) from Saturn between Mimas and Tethys at 32.9 hours. Now a new study has determined it's the right age to support life, too. Icarus , published online September 11, 2015; doi: 10.1016/j.icarus.2015.08.037 Published in Instead, the observations suggested that Enceladus, stretched and squeezed by Saturn’s powerful gravity, actually has a deep subsurface ocean.
The subsurface ocean of Saturn's moon Enceladus seems possibly habitable in many ways. Scientists have discovered that a subsurface ocean on Enceladus could have existed for billions of years, providing plenty of time for microbial alien life to emerge and evolve.
Does the subsurface ocean of Saturn's moon Enceladus contain any kind of life? Researchers found the magnitude of the moon's very slight wobble, as it orbits Saturn, can only be accounted for if its outer ice shell is not frozen solid to its interior, meaning a global ocean must be present. A global ocean lies beneath the icy crust of Saturn's geologically active moon Enceladus, according to new research using data from NASA's Cassini mission.
We've known there is water on Enceladus for a while now, but NASA has just confirmed a more recent theory about the icy moon of Saturn: it has a subsurface ocean that spans the entire globe. The discovery of an ocean below Enceladus’ surface immediately raised the moon’s profile in the early 2000s, since liquid water is crucial for life here on Earth. Inner complexity of Saturn moon, Enceladus, revealed: Enceladus' subsurface ocean composition hints at habitable conditions. The subsurface ocean of Saturn’s moon Enceladus seems possibly habitable in many ways. Tidal heating is the process in which an outside objects gravitational pull, Dione, pulls at the internal structure of another object causing it to expand when it is near.
ScienceDaily . What it probably means is that, just like Enceladus, Europa could have a subsurface ocean in which primitive forms of life may be able to survive. A global ocean lies beneath the icy crust of Saturn's geologically active moon Enceladus, according to new research using data from NASA's Cassini mission. Now a new study has determined it’s the right age to support life, too. Enceladus’s measured physical libration requires a global subsurface ocean.
But until today astronomers could only speculate on the specifics of the ocean. Enceladus' orbital eccentricity and tidal heating are affected by its sister moon Dione. The icy Saturn moon Enceladus harbors a large subsurface ocean of liquid water that may be capable of supporting life as it is known on Earth, a new study reports. Newfound complex organic molecules in its water vapor plumes hint we might not be alone in the solar system. ... (CO2) from within Enceladus, an ocean-harbouring moon of Saturn, ... abundance of CO2 is best explained by geochemical reactions between the moon’s rocky core and liquid water from its subsurface ocean.
The plumes are most likely from hydrothermal vents that erupt with hot water which shoots through the ice and into the darkness like liquid fireworks.
A moon with a diameter roughly the size of Great Britain was expected to be frozen solid and certainly not active.
