Life Detection Knowledge Base

The Knowledge Base (KB) of the Life Detection Forum (LDF) is an online repository of our current knowledge with regard to the detection of various signs of life and/or living processes. These signs, known as biosignatures, can vary from visually observable patterns to chemically measurable phenomena and even to signs of technological activity. The LDF KB is designed for easy browsing and searching of known biosignatures and includes descriptions of the criteria through which a biosignature may be counted as a robust sign of life. Furthermore, the KB provides a forum for scrutinizing the scientific literature, data, and arguments with regard to whether a suspected biosignature is truly diagnostic of living processes.
