A new theory for how oceans formed on ancient Mars also hints at the
best
spots for future fossil hunts on the red planet.
Based on the geology of Mars's northern plains, the new study suggests
that bodies of water formed as groundwater slowly seeped through cracks
in the crust. This process would have made oceans and lakes
quickly--within just a few years--but also could have sustained the
bodies of water over millennia.
However, even when Mars was supposedly wet, the planet likely didn't
have a very thick atmosphere. Many scientists therefore think that if
life as we know it evolved on Mars, the best places to look for it would
be where liquid water would have been protected from extreme temperature
changes and damaging ultraviolet radiation from the sun.
