Full report Exploration as a scientific endeavor exemplifies great American innovation. The first human steps on Mars will be a watershed moment for humanity and for science. The endeavor to […]
Debris-covered glaciers (DCGs) at the mid latitudes of Mars preserve ice accumulated in multiple episodes of high obliquity during the Amazonian age. The englacial debris layers formed during interglacials are […]
The Hawaiian islands are among the most geologically and volcanically active places on Earth. While the Hawaiian Archipelago is known for its animal and plant diversity, much less is known […]
Sources and sinks of methane within an advanced serpentinization-influenced system were investigated at the Coast Range Ophiolite Microbial Observatory (CROMO) in Lower Lake, California. Subsurface water-rock reactions at CROMO contribute […]
Exploration of oxygen-depleted marine environments has consistently revealed novel microbial taxa and metabolic capabilities that expand our understanding of microbial evolution and ecology.
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 […]
Vertical transmission of marine particles brings ocean surface cyanobacteria into the deep ocean, where heterotrophic cyanobacterial lineages probably evolve to adapt to new environments even in oxygen-depleted zones.
“Biosignatures and the Search For Life on Mars”, will be held in Iceland from 18 to 26 July 2026
The Institute of Space and Astronautical Science (ISAS) of the Japan Aerospace Exploration Agency (JAXA), in collaboration with Chuo University, Tokyo University of Agriculture and Technology, and CSIRO, Australia’s national […]
Hi Keith, The team and I have been home for about two weeks now, settling back into the familiar rhythms of home and work after our time in Antarctica. Our […]
