A sluggish mid-Proterozoic biosphere and its effect on Earth's redox balance
Kazumi Ozaki, Christopher T. Reinhard, Eiichi Tajika
The possibility of low but nontrivial atmospheric oxygen (O2) levels during the mid-Proterozoic (between 1.8 and 0.8 billion years ago, Ga) has important ramifications for understa…
Anoxygenic photosynthesis and the delayed oxygenation of Earth's atmosphere
Kazumi Ozaki, Katharine J. Thompson, Rachel L. Simister +2
The emergence of oxygenic photosynthesis created a new niche with dramatic potential to transform energy flow through Earth's biosphere. However, more primitive forms of photosynth…
Effects of primitive photosynthesis on Earth's early climate system
Kazumi Ozaki, Eiichi Tajika, Peng K. Hong +2
The evolution of different forms of photosynthetic life has profoundly altered the activity level of the biosphere, radically reshaping the composition of Earth's oceans and atmosp…
Rethinking CO Antibiosignatures in the Search for Life Beyond the Solar System
Edward W. Schwieterman, Christopher T. Reinhard, Stephanie L. Olson +4
Some atmospheric gases have been proposed as counter indicators to the presence of life on an exoplanet if remotely detectable at sufficient abundance (i.e., antibiosignatures), in…
The remote detectability of Earth's biosphere through time and the importance of UV capability for characterizing habitable exoplanets
Christopher T. Reinhard, Edward W. Schwieterman, Stephanie L. Olson +10
Thousands of planets beyond our solar system have been discovered to date, dozens of which are rocky in composition and are orbiting within the circumstellar habitable zone of thei…
The Super-Earth Opportunity - Search for Habitable Exoplanets in the 2020s
Renyu Hu, Charles A. Beichman, David Brain +23
The recent discovery of a staggering diversity of planets beyond the Solar System has brought with it a greatly expanded search space for habitable worlds. The Kepler exoplanet sur…
A Statistical Comparative Planetology Approach to Maximize the Scientific Return of Future Exoplanet Characterization Efforts
Jade H. Checlair, Dorian S. Abbot, Robert J. Webber +37
Provided that sufficient resources are deployed, we can look forward to an extraordinary future in which we will characterize potentially habitable planets. Until now, we have had…
The Importance of 3D General Circulation Models for Characterizing the Climate and Habitability of Terrestrial Extrasolar Planets
Eric T. Wolf, Ravi Kopparapu, Vladimir Airapetian +27
While recently discovered exotic new planet-types have both challenged our imaginations and broadened our knowledge of planetary system workings, perhaps the most compelling object…
A Limited Habitable Zone for Complex Life
Edward W. Schwieterman, Christopher T. Reinhard, Stephanie L. Olson +2
The habitable zone (HZ) is commonly defined as the range of distances from a host star within which liquid water, a key requirement for life, may exist on a planet's surface. Subst…
