The atmospheric composition of WASP-39 b has been revealed by the Webb Telescope.

While the Webb telescope provides a new menu on exoplanet environments, other space telescopes, including Hubble and Spitzer, have revealed individual elements in exoplanet atmospheres, and Webb has provided new readings on atoms, molecules and even That’s indicated by active chemistry and clouds.The atmospheric composition of the hot gas giant exoplanet WASP-39 b has been revealed by the Webb Space Telescope. Webb’s three instruments were used to plot the graphic of the exoplanet WASP-39 b,These instruments acquired four transmission spectra,all plotted on a common scale ranging from 0.5 to 5.5 µm.

Data from NIRISS in the top left of the image shows fingerprints of potassium (K), water (H2O) and carbon monoxide (CO), and data from NIRCam in the top right shows a prominent water signature. NIRSpec data on the bottom left of the image is shown indicating water, sulfur dioxide (SO2), carbon dioxide (CO2), and carbon monoxide (CO), NIRSpec data on the bottom right shows all of these molecules as well as sodium (Na)  The Webb telescope has produced a molecular and chemical profile of the exoplanet’s atmosphere.

WASP-39 b orbits a star about 700 light-years away, and Webb finds all these types of exoplanets – planets around other stars – giving the science community good clues about exoplanets. We observed the exoplanet with multiple instruments that, together, provide a broad swath of the infrared spectrum, says astronomer Natalie Batalha of the University of California.

Sulfur dioxide (SO2) has been discovered for the first time in the atmosphere of an exoplanet, a molecule produced by chemical reactions triggered by high-energy light from the planet’s parent star, and is how the protective ozone layer in Earth’s atmosphere is formed. Shang-Min Tsai, a researcher at the University of Oxford, says that for the first time we have seen solid evidence of photochemistry, a chemical reaction initiated by energetic stellar light, and the origin of sulfur dioxide in the atmosphere of WASP-39 b. offers us a promising approach in furthering the understanding of exoplanet atmospheres.

WASP-39 b orbits very close to its host star, and Webb tracked the planet to see its light, as passing in front of the planet allows some of the light to filter through the atmosphere, causing  Key Webb Different types of chemicals absorb different colors of the star’s spectrum, and the colors that are missing tell astronomers which molecules are present in the planet. Webb also discovered other atmospheric components in WASP-39 b’s atmosphere, including sodium (Na), potassium (K), and water vapor (H2O). Webb observed carbon dioxide (CO2) at high resolution,Which provides twice as much data as previous observations.

Carbon monoxide (CO) was detected from Webb’s data, but clear signatures of both methane (CH4) and hydrogen sulfide (H2S) were absent, if present, at very low levels. To capture WASP-39 b’s atmosphere across a broad spectrum, the researchers analyzed data from hundreds of Webb telescope’s finely calibrated instrument modes, allowing the researchers to build a chemical catalog of WASP-39 b’s ultimate goliath of a planet,suggests a history of smashups and mergers of smaller bodies for.
