Astrobiology, while traditionally focused on understanding the origin of life on Earth and the potential for life elsewhere, offers powerful tools and insights for addressing urgent challenges on our planet.
Methane forms beneath ice sheets through microbial methanogenesis and thermogenic breakdown of organic matter, creating a potentially large greenhouse gas reservoir prone to release during glacial retreat.
The primary purpose of this review is to present chemistry analysis. In this theoretical study exploring the origin of life, the main argument is that life on Earth may not […]
Decades of space exploration have shown that surface environments on Mars were habitable billions of years ago. Ancient, buried surface environments, or paleosols, may have been preserved in the geological […]
Differentiating biotic and abiotic processes in nature remains a persistent challenge, specifically in evaluating microbial contributions to geochemical processes through time. Building on previous work reporting that biologically-influenced systems exhibit […]
Extraterrestrial impacts are a ubiquitous process in the solar system, reshaping the surface of rocky bodies of all sizes. On early Earth, impact structures may have been a nursery for […]
