Exoplanet Biosignatures: Understanding Oxygen as a Biosignature in the Context of Its Environment
Victoria S. Meadows, Christopher T. Reinhard, Giada N. Arney +13
Here we review how environmental context can be used to interpret whether O2 is a biosignature in extrasolar planetary observations. This paper builds on the overview of current bi…
Exoplanet Biosignatures: Future Directions
Sara I. Walker, William Bains, Leroy Cronin +11
Exoplanet science promises a continued rapid accumulation of new observations in the near future, energizing a drive to understand and interpret the forthcoming wealth of data to i…
Exoplanet Biosignatures: A Review of Remotely Detectable Signs of Life
Edward W. Schwieterman, Nancy Y. Kiang, Mary N. Parenteau +15
In the coming years and decades, advanced space- and ground-based observatories will allow an unprecedented opportunity to probe the atmospheres and surfaces of potentially habitab…
Pale Orange Dots: The Impact of Organic Haze on the Habitability and Detectability of Earthlike Exoplanets
Giada N. Arney, Victoria S. Meadows, Shawn D. Domagal-Goldman +5
Hazes are common in known planet atmospheres, and geochemical evidence suggests early Earth occasionally supported an organic haze with significant environmental and spectral conse…
False negatives for remote life detection on ocean-bearing planets: Lessons from the early Earth
C. T. Reinhard, S. L. Olson, E. W. Schwieterman +1
Ocean-atmosphere chemistry on Earth has undergone dramatic evolutionary changes through its long history, with potentially significant ramifications for the emergence and long-term…
