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 ...NASA’s James Webb Space Telescope has discovered a new, never-before-seen feature in Jupiter’s atmosphere. The high-speed jet stream, which spans more than …

Caption: NASA’s JWST made the first identification of sulfur dioxide in an exoplanet’s atmosphere. Its presence can only be explained by photochemistry – chemical reactions triggered by high-energy particles of starlight. Photochemistry is essential to processes on Earth key to life like photosynthesis and the generation of our ozone layer.While lower regions of planet atmospheres are being studied at longer wavelengths with HST, and soon with JWST and the ground-based ELTs, UV spectroscopic ...The James Webb Space Telescope's unique capabilities have finally allowed a group of international scientists to observe CH3+ for the first time, confirming its central role in interstellar chemistry. The CH3+ signal was detected in the d203-506 star-protoplanetary disc system located approximately 1350 light years away in the Orion …JWST is the most powerful space telescope ever launched. With three of its four instruments, it obtained detailed infrared spectra from the star WASP-39. Scientists then got to work analyzing the colorful codes. First up was a census of the molecules present in WASP-39b's atmosphere.

Dec 2, 2022 · While WASP-39b is a gaseous hellscape, at 1500-degrees F, the discovery of sulfur-dioxide in the planet's atmosphere means that photochemistry is at work and confirms that the JWST is able to ... Just what will JWST uncover, for example, in the TRAPPIST-1 system? The two papers among the five that I’ve had the chance to go through are Tsai et al., “Direct Evidence of Photochemistry in an Exoplanet Atmosphere” and Alderson et al., ”Early Release Science of the Exoplanet WASP-39b with JWST NIRSpec G395H” . The other three papers ... ….

The data revealed new details of WASP-39b, a “hot Saturn” exoplanet located in the Virgo constellation. The planet made headlines in August when JWST identified carbon dioxide in its atmosphere — a major breakthrough as this was the first time carbon had ever been detected in an alien atmosphere. Now, JWST has provided the …CNN —. Astronomers have detected a crucial carbon molecule in space for the first time using the James Webb Space Telescope. The compound, called methyl cation, or CH3+, was traced back to a ...

Nov 22, 2022 · Astronomers discovered sulfur dioxide produced by photochemical reactions in an exoplanet atmosphere. New JWST observations of WASP-39b have provided a clearer picture of the exoplanet, showing the presence of sodium, potassium, water, carbon dioxide, carbon monoxide and sulfur dioxide in the planet's atmosphere.
