Could scientists find life in the clouds of exoplanet atmospheres? This is what a recently submitted manuscript hopes to address as a team of researchers investigated how the biosignatures of microbes could be identified in exoplanet atmospheres and clouds. This study has the potential to help scientists develop new methods for finding life on exoplanets, either as we know it or even as we don’t know it.
