How the James Webb Space Telescope Photographs Exoplanets: Coronagraphs, Spectra and the Fight Against Starlight
The James Webb Space Telescope uses coronagraphs to block host star glare and spectrographs to analyze planetary light, enabling direct imaging and atmospheric composition studies of exoplanets. This technique is particularly effective for young, wide-separation gas giants.
