Astronomers are searching for the perfect biosignature, like an atmospheric chemical that indicates life on any specific world. However, this method will always be controversial and inconclusive. A new paper proposes that detecting life on any one planet might be impossible, but it should be obvious at a larger statistical level. Civilizations or life drifting from star to star will change nearby worlds to be more appropriate for their needs in a detectable way.
