Scientists have developed a new approach to maximise the chances of identifying planets orbiting nearby stars that support life, by creating a comprehensive list of the gas molecules that may be present in the atmospheres of these exoplanets.
Biosignature gases emitted by exoplanetary life forms could be detected remotely by space telescopes, but these g
