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

SEEC 2024 Symposium

Recent exoplanet surveys from the ground have discovered myriad nearby systems that are non-transiting. Currently, the number of known non-transiting systems dominate by a factor of two compared to transiting ones within 20 pc, and by a factor of 9x within 10 pc. SEEC will host a interdisciplinary symposium which will focus on exploring pathways to characterize non-transiting planets - in particular, the regions of planetary parameter space that are not well represented in transiting planet characterization studies. Check this page for more information.

Technosignature seminar series

Observing the atmospheres of exoplanet's 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.
