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.


SEEC supports on-going seminar series as well as special retreats, symposiums, and workshops. Learn more by clicking on the boxes to the right.

EMAC workshop

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.

Technosignature seminar series

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.

GSFC Extrasolar Planets Seminar Series

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.
