A Framework for Detecting Life Beyond Earth: Biosignatures Structured as Substances, Objects, and Patterns

To the point

Detecting life beyond Earth relies on a framework that groups biosignatures into substances, objects, and patterns, acknowledges that abiotic processes can mimic them and create ambiguity, and relies on multi-scale context, big data, and standardized, open, interdisciplinary methods to distinguish biogenic signals from abiotic ones across planetary environments.

Deciphering Biosignatures in Planetary Contexts

Microbial life permeates Earths critical zone and has likely inhabited nearly all our planets surface and near subsurface since before the beginning of the sedimentary rock record. Given the vast time that Earth has been teeming with life, do ...
