Save the date for the 23rd Sagan Summer Workshop!

Observations of an exoplanet’s atmosphere provide the best hope for distinguishing the makeup of its outer layers, and the only hope for understanding the interplay between formation, natal composition, chemical and disequilibrium processes, and dynamics & circulation. The field is entering a revolution in our understanding of exoplanet atmospheres thanks to measurements from the ground, from space, and particularly from the new JWST – the superlative facility for exoplanet studies. In the longer term, such observations will also be essential for seeking signs of biosignature gasses in nearby exoplanets using future, next-generation observatories.

This year’s workshop will cover theoretical modeling, interpretation, and observations of exoplanets using a variety of telescopes, techniques, and hands-on exercises, presented by leading experts in the field.

We currently plan to hold the 2023 workshop as a hybrid with both in-person and on-line attendance. It is unclear at this time (September 2022) what, if any, restrictions will be in place due to COVID. This page will be updated with more information in the coming months and we expect registration will open in February 2023.

The Sagan Summer Workshops are aimed at advanced undergraduates, grad students, and postdocs, however all are welcome to attend. There is no registration fee for these workshops.

Attendees will also participate in hands-on tutorials and have the chance to meet in smaller groups with our speakers.

All participants must follow this Code of Conduct.
