Biogeology: A deep subject
Way down deep, below the lowest depths of the oceans, below the floor of the seas – in the rock of the ocean crust – there exists a world with life. It’s been known for some time that bacteria can live in rock. According to the research done by Martin Fisk and colleagues at the [...]

Life under an Antarctic glacier
Suppose you’re standing on a glacier in Antarctica, twelve miles (19 km) from the sea, and you drill a hole in the ice to get a core sample. Down about 600 feet (180 meters), you hit a little bit of water, and you think, “It’s unfrozen water. Could be something living in this – a [...]

Enceladus has (at least) a sea, possibly life
It’s all but official. New data released from the Cassini spacecraft has confirmed that Enceladus, one of the moons of Saturn, has liquid water – as a sea – underneath its exterior layer of ice. The idea of Enceladus having large bodies of liquid water is not new but thanks to Cassini, the evidence is [...]

On the Moon or elsewhere: Follow the water
In the detective business, the standard advice is: “Follow the money.” In human space exploration, perhaps somewhat similar advice applies: “Follow the water.” This needs debate, however there are some potent arguments in favor of the notion that human (as differentiated from robotic or probe) exploration of space should go where sources of water are [...]
