The Team
The NExSS project is overseen by representatives from NASA HQ, three co-leads, and a Steering Committee composed of the PIs of funded proposal teams selected to be the founding members of NExSS.
Many Worlds
Many Worlds is a website for everyone interested in the burgeoning field of exoplanet detection and research. It presents columns, news stories and in-depth features, as well as the work of guest writers.
Recent Research
Pale Blue Reflections: Investigating the Atmospheres of Earth Analogs with Future Space Imaging Missions (Jonathan Fortney, PI)
We have created a retrieval framework for future space-based direct imaging missions to constrain properties of Earth-like planets. We simulate albedo spectra of Earth that WFIRST, HabEx, and LUVOIR may measure. With inverse modeling, we can determine our ability to measure important quantities related to habitability. To detect atmospheric water vapor, molecular oxygen, and ozone abundance, we need data at spectral resolution of 70 and signal-to-noise ratio of 20; to constrain these abundances, we need data at resolution of 140, signal-to-noise ratio of 20.
