Where To Look?

A few scientists are trying to pin down where the best places for life might be elsewhere in the universe:

“When people talk about ‘habitable zones,’ they mean where there’s liquid water on the surface. But there’s liquid water elsewhere in the solar system; it’s buried under thick sheets of ice on moons,” Francis Nimmo, a planetary scientist with the University of California at Santa Cruz, told Discovery News.

Nimmo is among a growing cadre of scientists who believe the search for life beyond Earth should be focused on selected moons of Jupiter and Saturn, where liquid oceans or lakes are believed to exist beneath the frozen ground.

Large bodies of liquid water with geothermal activity? Sounds like a good bet.
