Lab experiments constrain conditions necessary for a key mineral to have formed in ancient lagoons and a crater lake.
A multinational research team drilled into the seafloor to see whether chemical processes in exposed shallow mantle rocks could generate nutrients to support life in the subsurface.
If present, microbes could explain evolving patterns in the planet’s atmosphere when observed in ultraviolet light.
Some pools of salty water on the Red Planet could contain enough dissolved oxygen for microorganisms and sponges to survive, new calculations suggest.
Conditions are right for “penitentes” up to 15 meters high to form on the Jovian moon, new research shows. The spires might prevent a lander from exploring Europa’s equatorial region.
Recent research suggests that NASA’s next-generation space telescope will be good—but not the best—at finding life-sustaining levels of oxygen in an exoplanet’s atmosphere.
Scientists unravel the conditions under which life evolved to breathe oxygen—and the findings have some stellar implications.
Lacking light and energy, under-seafloor microbes rely on ancient organic materials to survive.
A volcanically heated Costa Rican lake hosts only one type of organism, suggesting that its Mars-like environment is just barely capable of supporting life.
Cobalt may have played in important role in the early development of life on Earth, and been more available to ancient life than modern due to the higher mafic composition of early continents.
