Editor’s note: If we aspire to mount expeditions to new worlds and then embrace the task of characterizing and quantifying whatever life forms we find, the ability to map and […]
Editor’s note: When we start to mount Astrobiology missions to explore ocean worlds we’ll need ways for our robotic submersibles to observe and interact with whatever life forms they may […]
While NASA imagery has shown evidence of ancient rivers and lakes on Mars that transitioned to dry dunes, uncertainty remains over the timing of the environmental changes that may have […]
The vast chemical space of possible small molecules, estimated at 1060 compounds for molecules composed of just C, N, O, and S, is only sparsely occupied by biology.

Rock-dwelling chlorolichens and cyanobacteria provide most of the total biomass of the ice-free zone of Antarctica, i.e., the McMurdo Dry Valleys (MDV), and yet, the water sources of MDV are […]
How microbial communities respond to extreme conditions in the stratosphere remains unclear.
