In a groundbreaking discovery, NASA’s James Webb area telescope has revealed a planet the place specks of sand fall as rain, the Guardian reported. Although the planet has the same water and cloud cycle to Earth, its clouds are made from sand and the clouds are made from silicate. This distinctive Jupiter-sized exoplanet, known as Wasp-107b, is 200 mild years away from Earth within the constellation Virgo. Wasp-107b can also be sometimes called the ”sweet floss” as it’s a lot much less dense than different big gasoline planets. Despite the fact that the planet is concerning the dimension of Jupiter, it’s a lot lighter, with about the identical mass as Neptune.
”In truth, this fluffy planet has one of many lowest densities we have ever seen. That permits us to essentially look very deeply into the environment of that planet”, Prof Leen Decin, of the Catholic Institute (KU) Leuven and first writer of the analysis instructed New Scientist.
Notably, a staff of European astronomers used JWST’s Mid-Infrared Instrument (MIRI) to element the atmospheric composition of the planet. Researchers discovered water vapor, sulfur dioxide, and silicate sand clouds residing inside the exoplanet’s dynamic environment. Their observations have been printed in Nature.

Though clouds have been detected on exoplanets earlier than, that is the primary time their chemical composition has been analysed by astronomers.
This planet’s environment features equally to Earth’s water cycle, however with sand as a substitute of water. When silicate vapour rises from the warmer, decrease ranges of the environment and cools, it kinds microscopic grains of sand. Finally, these sand clouds turn into dense sufficient to rain again right down to the decrease layers of the planet’s environment.

”The invention of clouds of sand, water, and sulfur dioxide on this fluffy exoplanet by JWST’s MIRI instrument is a pivotal milestone. It reshapes our understanding of planetary formation and evolution, shedding new mild on our personal Photo voltaic System,” Mr Decin added.
”It is an incredible goal as a result of it is actually fluffy. It is one of many fluffiest planets on the market and so they’re those we will get these huge indicators after we have a look at their environment. We have been engaged on predictions for the previous 10 years however nothing has fairly ready us for what we’re really seeing – each what we’re discovering out and the standard of the information. It has been actually thrilling,” stated Dr Joanna Barstow, a planetary scientist at Open College who’s engaged on separate JWST measurements of the identical planet.
