Earth’s Hidden Biospheres
Two recent discoveries in astrobiology challenge many of our assumptions about an integrated biological community on Earth. At the microbial level, it seems that there may be previously hidden biospheres that exist on Earth alongside our more familiar neighbors. One such community has been found deeply buried underground, while the other lives in the sea alongside more familiar life forms.

Microbes of the Deep
In this week’s Science, researchers from NAI’s Indiana, Princeton, Tennessee Astrobiology Initiative (IPTAI) and Carnegie Institution of Washington Teams report that they have found an extant microbial biome at 2.8km depth in a South African mine. Analyses showed thermophilic sulfate reducers existing “with no apparent reliance on photosynthetically derived substrates.”
