Venusian Climate May Have Been Habitable
tqft writes "Venus - life signs maybe - 'The hellish climate of Venus may have arisen far more recently than previously supposed, suggests new research. If so, pleasant Earth-like conditions probably persisted for two billion years after the planet's birth - plenty of time for life to have developed.' Mars is for wimps afraid of a real hot acid drenched challenge."

Oxygen is a dangerous poison. Most early life (and lots still extant) not only do not need oxygen but are harmed by oxygen. Early life was probably based on hot methane plumes in the Earth's oceans, which is not dependent upon the sun, nor on oxygen.
I'd do something interesting, but my server can't handle a slashdotting.
Perhaps not just water, but any kind of ocean or atmosphere that can boil away to provide a nice temperature gradient. There is an interesting article at: This dynamic earth, USGS
