Five places where life may exist in solar system

Washington: Life on Earth occupies some bizarre places from deep-sea hydrothermal vents to frigid and lightless lakes. While scientists hunt for hospitable planets circling other stars, the solar system has a few candidates.

According to the Christian Science Monitor, the following are the five places where life may exist:

Mars:

Early in its history, the red planet had abundant surface water. Could microbes lurk underground?

Europa/Ganymede:

With rocky cores heated by tugs from Jupiter, these moons are thought to have potentially life-supporting seas beneath their icy crusts.

Enceladus:

This icy moon of Saturn also has subsurface deposits of liquid water or slush, a rocky core, and Saturn`s gravity for heat. Active ice volcanoes could be circulating nutrients that life forms could use.

Titan:

Saturn`s largest moon has lots of hydro-carbons as raw material for biologically important molecules. It`s extremely cold. Could life exist underground?

Venus:

It`s a long shot, with its crushing atmosphere and surface temperatures that would melt lead. But 30 miles up, conditions might be more favourable. Bacteria on Earth endure much worse.
