The sequence below comes from this topic's published material. Sections expand or contract with the subject instead of forcing every lesson into the same five-step mold.
Evidence
Evidence for Transmission & Emission Spectroscopy
Space telescopes have detected water, carbon-bearing molecules, alkali metals, clouds, and thermal structures in exoplanet atmospheres. Repeated observations and retrieval models quantify molecular abundances with uncertainties and degeneracies.
Chapter review
Assessment still in review.
The chapter is published, but its assessment has not completed the verification and QA pipeline yet. It will appear here after publication.
