AKIPRESS.COM - NASA scientists have recently announced the largest moon in outer space may have ice and liquid oceans “stacked up” in several layers like the club sandwich and apparently can support life, International Business Times reported.

“That would make it the largest club sandwich in the solar system,” Steve Vance of NASA's Jet Propulsion Laboratory (JPL) in Pasadena (California), leading the study for the NASA-funded research, said.

The study led by Vance has provided new “theoretical evidence” for the research team's club sandwich model, which was first proposed in 2013.

NASA added the results provided a possibility that the icy moon Ganymede must have harbored “primitive life.”

“The first layer on top of the rocky core might be salty water,” NASA said, adding scientists say places where there is an interaction between water and rock are more likely to develop life.

Basing on models of Ganymede, NASA cited scientists first suspected an ocean in the largest moon in outer space in the 1970s. In the 1990s, it was confirmed that there are oceans with evidence for “salty seas” in the icy moon through NASA's Galileo mission.

Ganymede is only one of five moons in the solar system thought to support vast oceans beneath icy crusts.
