Artist's conception of what life could look like on the surface of a distant planet.On our quest to find life beyond Earth, scientists first must have to ask themselves: what signs would be the most compelling evidence?This artist's concept shows Kepler-11 -- the most tightly packed planetary system yet discovered.Participants in AbSciCon 2018.There are a plethora of journals publishing scientific results relevant to astrobiology. It is important to seek advice from your advisors and colleagues so that you can make an educated choice when publishing your data.
