what archaea found in lava
The microbes were collected from a lava tube near Newberry Crater in Oregonâs Cascades Mountains, at an elevation of about 5,000 feet. They were within the ice on rocks some 100 feet inside the lava tube, in a low-oxygen, near-freezing environment.Conditions in the lava tube are not as harsh as on Mars,â Fisk said. âOn Mars, temperatures rarely get to the freezing point, oxygen levels are lower and at the surface, liquid water is not present. But water is hypothesized to be present in the warmer subsurface of Mars.
