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.
