SOLAR SYSTEM

Detailed explanation-1: -Enceladus, the sixth moon of Saturn, is roughly the size of the United Kingdom and covered in miles-thick ice. Underneath is a liquid ocean, which bursts out of the surface through a series of cracks at the southern pole, sending a constant geyser spraying out into space.

Detailed explanation-2: -In a process called tidal heating, gravitational tugs from Jupiter’s moons and the planet itself stretch and squish the moons enough to warm them. As a result, some of the icy moons contain interiors warm enough to host oceans of liquid water, and in the case of the rocky moon Io, tidal heating melts rock into magma.

Detailed explanation-3: -Few worlds in our solar system are as compelling as Saturn’s icy ocean moon Enceladus. A handful of worlds are thought to have liquid water oceans beneath their frozen shell, but Enceladus sprays its ocean out into space where a spacecraft can sample it.

Detailed explanation-4: -Saturn’s moon Enceladus is famous for the huge water-vapor geysers at its south pole, which are thought to originate from a global ocean deep beneath the moon’s outer ice crust.

Detailed explanation-5: -The geysers of Enceladus: huge plumes of water vapor erupting through cracks at the south pole of this moon of Saturn. The plumes contain water vapor, ice, salts, methane and both simple and complex organic molecules, the kind of molecules normally found in living systems.
