Scientists Propose Radical New Way To Detect Alien Life – Without Traditional Biosignatures

Researchers propose an agnostic biosignature framework that looks for statistical patterns across many exoplanets, rather than relying on a single life marker.

The method uses planetary similarities and spatial clustering, backed by agent-based simulations, to identify where life may have spread and altered worlds.

Led by Harrison B. Smith and Lana Sinapayen, the approach is designed to detect life even when traditional biosignatures are ambiguous.

If validated, it could reduce false positives and help astronomers prioritize limited telescope time for the most promising targets.
