The Earth’s Lyman-α geocorona as observed from a distance of 0.1 au (panel a). The Earth’s exosphere is predominantly composed of neutral hydrogen, which escapes the lower atmosphere after being photodissociated into H and O atoms.95 Panel b represents the illumination of Earth by the Sun at the time of the observation. HWO may be capable of detecting this feature in Earth-like exoplanets, and we aim to make sure the its UV spectrograph is capable of doing so. -- astro-ph.EP
