Water is vital for life as we know it. But not all water has life living in it. By combing through data from extreme environments, researchers have found the limits of what constitutes habitable water conditions on our planet. This could help us figure out what types of water on other planets would be more likely to host life.
The guiding principle in our current search for alien biology is "follow the water." But the new research suggests this target needs to be refined.
"Should we follow the hot water or maybe the cold water?" asks Eriita Jones of the Australian National University, lead author of the study that appears in the latest issue of the journal Astrobiology.
