However, no unambiguous ... Our transmission spectrum shows additional opacity centered at 8.6 μ m, and detailed atmospheric modeling and retrievals identify this feature as SiO 2 (s) (quartz) clouds. The SiO 2 (s) clouds model is preferred at 3.5–4.2 σ versus a cloud-free model and at 2.6 σ versus a generic aerosol prescription. We find the SiO 2 (s) clouds are ...Humanity’s latest space telescope is giving us a clearer picture of planets far outside our solar system.After many delays, a Christmas launch, and a months-long period of travel and testing, the first science images from the James Webb Space Telescope (JWST) …
