The geologic record suggests that despite Earth’s hot, thin crust during the Proterozoic, mountains were still able to form thanks to an extinct style of crustal deformation.
A new study challenges the assumption that cyanobacteria were the only major nitrogen fixers in the Proterozoic eon.
New research finds that Actinobacteria in lava caves fix carbon and survive independent of surface inputs, offering a fresh perspective in the search for life beyond Earth.
Microbial mats in a Lake Huron sinkhole, combined with modeling work, suggest that the changing length of Earth’s day could have played a key role in oxygenating the atmosphere.
Scientists seek to understand the elusive properties of stellar and galactic cosmic rays before searching for life on exoplanets.
On early Earth, rock created by lightning strikes to the ground likely held a form of phosphorus necessary for prebiotic chemistry.
Algún día, un catálogo de fragmentos moleculares podría ayudar a científicos a identificar vida extraterrestre en las lunas heladas de nuestro sistema solar.
A new study of seafloor sediments finds that the temperature record in the early Paleozoic corresponds to significant shifts in the diversity of life on Earth.
Someday, a catalog of molecular fragments might help scientists identify extraterrestrial life on our solar system’s icy moons.
New analysis indicates that planetary feedbacks alone don’t make habitability an inevitability.
