See that blue stuff in the back that's steaming? That's near-boiling water.

See all that orange shit everywhere that looks like someone covered the ground with iron and waited for it to rust? That's bacteria. An actual carpet of bacteria. A whole floor of living things. Nasty stuff. They're called Thermophiles and Extremophiles because of the conditions they live in. Some of these strains of bacteria are aiding in both DNA sequencing and looking into seeing if similar kinds of life can exist on Mars.

Cool shit, huh?
