Astrobiologists continue to find a single definitive biosignature, a single chemical that could be found in the atmosphere of an exoplanet that screams, "there's life here." In a new paper, researchers propose that you need multiple planets in a system to know if you're looking at exo-forests or exo-volcanoes. If there are inhospitable planets in a system, they can serve as an abiotic baseline that you can compare with potentially habitable worlds to see life’s signals.
