| contents | Subsurface Life on Earth as a Key to Unlock Extraterrestrial Mysteries. Vidal, Emeline Lindsay, Melody R Bradley, James A Osburn, Magdalena R Ruff, S Emil Earth, Planet Exobiology Extraterrestrial Environment Geologic Sediments Microbiota Origin of Life The first forms of life on Earth were microbial, preceding the evolution of multicellular life by more than two billion years. Based on our current understanding of the origin of life, it is likely that the first life forms on any extraterrestrial world would also be microbial. Due to the extreme temperatures, radiation or aridity on most planetary surfaces, such extraterrestrial microbes would most likely dwell in subsurface environments. Earth's subsurface features a wide range of environments, including deep marine sediments, crustal aquifers, rock fracture fluids, hydrocarbon reservoirs, caves and permafrost soils. These environments are known to host an immense diversity of life forms, predominantly microbes that survive or even thrive under extreme conditions and energy scarcity. Life's ability to endure and possibly evolve in Earth's subsurface lends credence to the possible existence of life beyond our planet and provides a blueprint for the extraterrestrial life forms and biosignatures we might expect. The exploration of space via extraterrestrial samples analysed on Earth, in situ extraterrestrial analyses, and remote sensing continue to advance our search for and understanding of potential biosignatures on other planetary bodies. But by investigating Earth's deep, dark and isolated ecosystems, we not only broaden our understanding of life's adaptability but also refine our strategies and technologies for detecting life on other planets and moons. Subsurface exploration is not just a frontier of Earth science-it is a cornerstone of astrobiology and in the pursuit of understanding the multitude of processes that could create and sustain life anywhere. In this opinion article, we discuss the latest highlights in subsurface research and technology, how Earth's subsurface environments serve as models for potential environments on other planetary bodies, why insights into subsurface microbiomes inform the search for life elsewhere, and which technologies and developments will advance the field in the future. |
