Mars Images Reveal Evidence of Ancient Lakes

Matt_dk writes "Spectacular satellite images suggest that Mars was warm enough to sustain lakes three billion years ago, a period that was previously thought to be too cold and arid to sustain water on the surface, according to research published today in the journal Geology. Earlier research had suggested that Mars had a warm and wet early history but that between 4 billion and 3.8 billion years ago, before the Hesperian Epoch, the planet lost most of its atmosphere and became cold and dry. In the new study, the researchers analysed detailed images from NASA’s Mars Reconnaissance Orbiter, which is currently circling the red planet, and concluded that there were later episodes where Mars experienced warm and wet periods."

    Taking images of Mars is fine, but if they start taking pictures of Uranus you should call the police.

      Even toddlers are mature enough to know that your "joke" reeks of pathetic immaturity. Seriously, even an embryo with a partially-grown brain stem would find your attempt at humor to be absolute shit.
