This is stated in the Institute’s press release, Ukrinform reports.

Astronomers found not only water vapor and sulfur dioxide but also silicate (sand) clouds in WASP-107b’s atmosphere. These particles are in a dynamic atmosphere that exhibits a dense flow of material.

At the same time, astronomers found no trace of the greenhouse gas methane in WASP-107b. First of all, it is stated that the absence of methane indicates that the interior of the planet is potentially hot. Second, the discovery of sulfur dioxide came as a big surprise because previous modeling had predicted its absence. However, new climate models of WASP-107b’s atmosphere now show that WASP-107b itself contributes to the buildup of sulfur dioxide in its atmosphere.

Although its host star emits a relatively small proportion of high-energy photons due to its cold nature, these photons can penetrate deep into the planet’s atmosphere due to its “puffy” nature. This allows you to create the reactions necessary for the formation of sulfur dioxide.

“The discovery of sand clouds, water and sulfur dioxide on this ‘puffy’ exoplanet by James Webb’s MIRI (Mid Infrared Instrument – ed.) instrument is a major milestone. It transforms our understanding of the formation and evolution of planets and sheds new light on our solar system.” “It holds,” said Professor Leine Desin from the University of Leuven.

As reported by Ukrinform, an international research group, the first evidence that the black hole at the center of the M87 galaxy rotates was obtained as a result of analysis of images obtained as a result of more than 20 years of observations.
