(PhysOrg.com) -- While geological evidence points to the presence of liquid water on Mars during the Noachian epoch (the period from 4.5 to 3.5 billion years ago), determining the temperature of that water – a factor ...
For life as we know it to develop on other planets, those planets would need liquid water, or oceans. Geologic evidence suggests that Earth's oceans have existed for nearly the entire history of our world. But would that ...
