How does water form on exoplanets and what could this mean for the search for life beyond Earth? This is what a recent study published in Nature hopes to address as an international team of scientists investigated the processes responsible for exoplanets producing liquid water. This study has the potential to help scientists better understand the conditions for finding life beyond Earth, and specifically which exoplanets could be viable future targets for astrobiology.
