Sellers Exoplanet Environments Collaboration
A multidisciplinary effort at NASA Goddard Space Flight Center to study the broad diversity of exoplanet environments
The Sellers Exoplanet Environments Collaboration (SEEC) brings together multi-disciplinary researchers from the Planetary, Earth, Astrophysics, and Heliophysics science divisions at NASA’s Goddard Space Flight Center to study exoplanet atmospheres and climates. Using a wide range of scientific and technical resources, SEEC scientists inform current NASA exoplanet observations and prepare for future missions.
Key Questions Guiding SEEC Research
By studying ways that biospheres interact with planetary environments, SEEC researchers are pioneering methods to detect life on other worlds.
A vast multitude of physical, chemical, and geological processes combine to produce the characteristics of a specific exoplanet’s atmosphere and surface that will be visible to future telescopes.
Planetary habitability results from a complex network of interactions between the planet, its planetary system, and host star.
In our quest to find life outside of our solar system, we look for planets that resemble Earth, the only planet that we know of that is habitable.
Earth is our only example of a planet that is habitable and inhabited, and as such represents the archetypical habitable environment for remote sensing and mission development studies.
Events
SEEC supports on-going seminar series as well as special retreats, symposiums, and workshops. Learn more by clicking on the boxes to the right.
The first Exoplanet Modeling Analysis Center (EMAC) workshop will be held virtually on February 7-9, 2023. This event will showcase invited and contributed talks as well as workshops from the exoplanet developers and teams which have built and supported the various resources that can be found on the EMAC repository. You can still register to attend the conference for free using this link.
Observing the atmospheres of exoplanets can reveal a lot about their composition and history. These observations may even contain signs of current or past habitability. The NASA GSFC technosignature seminar series explores what sort of evidence advanced civilizations may leave behind that could be detected by future missions.

The GSFC Exoplanet seminar series is hosted virtually every other Thursday featuring GSFC and external exoplanet scientists. Topics range from observations and atmospheric modeling to planetary interiors and orbital dynamics. Click here to watch past talks or learn about future speakers.
