JWST/NIRISS reveals the water-rich "steam world" atmosphere of GJ 9827 d
Caroline Piaulet-Ghorayeb, Bjorn Benneke, Michael Radica +30
With sizable volatile envelopes but smaller radii than the solar system ice giants, sub-Neptunes have been revealed as one of the most common types of planet in the galaxy. While t…
The erosion of large primary atmospheres typically leaves behind substantial secondary atmospheres on temperate rocky planets
Joshua Krissansen-Totton, Nicholas Wogan, Maggie Thompson +1
Exoplanet exploration has revealed that many$\unicode{x2013}$perhaps most$\unicode{x2013}$terrestrial exoplanets formed with substantial H-rich envelopes, seemingly in contrast…
Constraining Background N2 Inventories on Directly Imaged Terrestrial Exoplanets to Rule Out O2 False Positives
Sawyer Hall, Joshua Krissansen-Totton, Tyler Robinson +2
Direct imaging spectroscopy with future space-based telescopes will constrain terrestrial planet atmospheric composition and potentially detect biosignature gases. One promising in…
Community Report from the Biosignatures Standards of Evidence Workshop
Victoria Meadows, Heather Graham, Victor Abrahamsson +72
The search for life beyond the Earth is the overarching goal of the NASA Astrobiology Program, and it underpins the science of missions that explore the environments of Solar Syste…
The Case and Context for Atmospheric Methane as an Exoplanet Biosignature
Maggie A. Thompson, Joshua Krissansen-Totton, Nicholas Wogan +2
Methane has been proposed as an exoplanet biosignature. Imminent observations with the James Webb Space Telescope may enable methane detections on potentially habitable exoplanets,…
Understanding planetary context to enable life detection on exoplanets and test the Copernican principle
Joshua Krissansen-Totton, Maggie Thompson, Max L. Galloway +1
The search for life on exoplanets is motivated by the universal ways in which life could modify its planetary environment. Atmospheric gases such as oxygen and methane are promisin…
