The Hubble Telescope detects evidence of a weather system on an exoplanet


NASA’s Hubble Space Telescope detected possible signs of a weather system on an extremely hot outer planet the size of Jupiter, with surface temperatures of 2,192 degrees Fahrenheit, as researchers from the Dutch SRON Institute for Space Research and the University of Groningen examined the WASP-31b images taken by the famous telescope.

According to the British newspaper “Daily Mail”, the WASP-31b is gradually closed, with one side always facing its host star the size of the sun, and in the “twilight zone” between the two regions, temperatures reach 2,192 degrees Fahrenheit.

Experts found evidence of chromium hydride in this region at temperatures and pressures that could allow it to switch between liquid and gas, forming a weather regime during rains on the night side and as a gas in the day.

The team says this is an important finding, because the weather system is a key feature that astronomers look for when finding a planet suitable for life, and finding a planet in such an inhospitable world could make the process easier.

The exoplanet is about 1.5 times the size of Jupiter but roughly half its mass, as it orbits its star every 3.4 days.

“Hot Jupiters, including WASP-31b, always have the same side facing the host star, so we would expect a day side with chromium hydride in gaseous form, and a night side with chromium hydride,” said Michael Main, associate researcher and head of the exoplanet program at SRON. Liquid. ”

Exoplanets are currently very far from the arrival of human-made probes, but telescopes and equipment on Earth can provide a glimpse of their atmosphere.
