Cassini mission scientists have suggested the existence of a subglacial ocean of Enceladus. It is reported by NASA.
They believe that the porous core of Saturn does not allow the ocean beneath its surface to freeze.
“Under the icy surface of a celestial body hiding a global ocean, and the geysers are the result of hydrothermal activity. The researchers assessed the density of the nucleus of Enceladus and came to the conclusion that it consists of porous rocks, and 20-30% of its volume consists of voids that fall of ocean water”, – stated in the message.
According to the simulation, the tidal force of Enceladus lead to a friction between fragments of the core, resulting in heat.
Ocean water circulates through the holes heats up and forms updrafts at temperatures up to 90 degrees Celsius.
Enceladus is geologically active, and the sixth largest moon of Saturn, was opened in 1789, but remained little-studied until the early 1980s, when he was approached by two interplanetary probe Voyager. A diameter of about 500 km. the Surface reflects almost all the incident sunlight. In 2005, the study of Enceladus began the interplanetary probe Cassini. The probe was opened rich water plume flowing from the southern polar region. One of the three celestial bodies in the outer Solar system (along with Jupiter’s moon IO and Neptune’s moon Triton) where there was an active eruption.
