Reflected Spectroscopy of Small Exoplanets. III. Probing the UV Band to Measure Biosignature Gases
Direct-imaging observations of terrestrial exoplanets will enable their atmospheric characterization and habitability assessment. Considering Earth, the key atmospheric signatures for the biosphere are O _2 and the photochemical product O _3 . However, this O _2 –O _3 biosignature is not detectable...
