General Observer Programs in Cycle 2. The proposals listed below establish the program for JWST’s second year of science operations. Approximately 5,000 hours of prime time and up to 1,215 hours of parallel time were awarded to observing programs in this Cycle 2. STScI hosted the Cycle 2 Telescope Allocation Committee in April 2023.Nov 22, 2022 · NASA’s James Webb Space Telescope made the first identification of sulfur dioxide in an exoplanet’s atmosphere. Its presence can only be explained by photochemistry – chemical reactions ... Now the JWST has turned its incredibly powerful eye on an exoplanet for the first time. WASP-39b is a gas giant about the mass of Saturn but slightly larger in diameter than Jupiter. We mostly think of gas giants as being distant from their stars, but that isn’t the case here. WASP-39b orbits only about 0.0486 AU — the average distance from ...This is a primary photochemical reaction: (28-1) The subsequent steps are dark reactions. At temperatures much above room temperature, the ethanoyl radical breaks down to give another methyl radical and carbon monoxide: (28-2) If this reaction goes to completion, the principal reaction products are ethane and carbon monoxide: (28-3) 2 …Home/Universe/ JWST discovered PHOTOCHEMISTRY in an exoplanet's atmosphere (this is a BIG deal) ft.

Synopsis. It looks like we don't have a Synopsis for this title yet. Be the first to contribute!A broad-wavelength 0.5–5.5 µm atmospheric transmission spectrum of WASP-39b, a 1,200 K, roughly Saturn-mass, Jupiter-radius exoplanet, demonstrates JWST’s sensitivity to a rich diversity of ...

JWST has been watching the Trappist system a lot. But each planetary transit only lasts for like 5 hours and that's only enough time to use a couple of filters each time. The data hasn't been released yet because the scientists involved have 1 year to work on the data before they have to release it. ical equilibrium. Recently, JWST observations of WASP-39 b have revealed the presence of SO 2, which represents the first di-rect evidence of photochemistry in a hot exoplanet atmosphere (Tsai et al. 2023a). Similar to the mechanism of HCN, SO 2 is produced if its parent species H 2S loses its hydrogen through re-Nov 23, 2022 · NASA’s James Webb Space Telescope 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. Nov 22, 2022 · The higher-resolution JWST data reveals the first indication of a photochemical byproduct — a chemical reaction accelerated by starlight — on an exoplanet. This and other findings are included in a set of five new scientific papers, three of which are in press and two of which are under review.

Dr. Becky explains why WASP-39b was chosen for early exoplanet exploration using the James Webb Space Telescope (JWST) and why the ability to detect photochemistry is so important. While WASP-39b ...The first JWST observations of TRAPPIST-1 c showed a secondary eclipse depth of 421+/-94 ppm at 15 um, which is consistent with a bare rock surface or a thin, O2-dominated, low CO2 atmosphere (Zieba et al. 2023). Here, we further explore potential atmospheres for TRAPPIST-1 c by comparing the observed secondary eclipse depth to synthetic spectra of a broader range of plausible environments. To ...…
