James Webb Telescope Discovers Jupiter-Sized 'Fluffy' Planet Where Sand Falls As Rain

Wasp-107b is known as the ”sweet floss” as it’s a lot much less dense than different large gasoline planets.

In a groundbreaking discovery, NASA’s James Webb house telescope has revealed a planet the place specks of sand fall as rain, the Guardian reported. Although the planet has an identical water and cloud cycle to Earth, its clouds are fabricated from sand and the clouds are fabricated from silicate. This distinctive Jupiter-sized exoplanet, known as Wasp-107b, is 200 gentle years away from Earth within the constellation Virgo. Wasp-107b can be also known as the ”sweet floss” as it’s a lot much less dense than different large gasoline planets. Though the planet is concerning the dimension of Jupiter, it’s a lot lighter, with about the identical mass as Neptune. 

”In actual fact, this fluffy planet has one of many lowest densities we have ever seen. That enables 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 advised 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 revealed 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 capabilities equally to Earth’s water cycle, however with sand as an alternative 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 develop 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 gentle on our personal Photo voltaic System,” Mr Decin added. 

”It is a terrific 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 large alerts once we take 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,” mentioned Dr Joanna Barstow, a planetary scientist at Open College who’s engaged on separate JWST measurements of the identical planet.
