How would detecting methane help astronomers identify if exoplanets, or even exomoons, have life as we know it, or even as we don’t know it? This is what a recent study published in The Astronomical Journal hopes to address as a team of researchers led by the NASA Goddard Space Flight Center investigated how a method called BARBIE (Bayesian Analysis for Remote Biosignature Identification on exoEarths) could be used on a future space mission to detect methane (CH4) on Earth-like exoplanets in optical (visible) and near-infrared (NIR) wavelengths.
