Stones also melt in these planets, NASA discovered exoplanets with 3 thousand degrees Fahrenheit

NASA scientists have discovered planets where temperatures exceed 3,000 degrees Fahrenheit (about 1650 degrees Celsius), enough to melt even titanium. In the course of their study of ultra-hot exoplanets, teams of astronomers working with the NASA Hubble Telescope reported WASP-178b, an exoplanet 1300 light years away.

Astronomers using NASA’s Hubble Space Telescope had got That a part of WASP-178b always remains in front of its burning star. During the day it has been observed that the atmosphere on exoplanets is surrounded by silicon monoxide gas. At the same time, towards the dark side, silicon monoxide is cold enough to turn into rocks falling from the sky. But at dawn and dusk, these same rocks evaporate due to hot temperatures. This study was published in the journal Nature.

“When you look at Earth, all of our weather predictions are still fine-tuned, which we measure,” said co-author David Sing on two studies from Johns Hopkins University in Baltimore, Maryland. But when you go to distant exoplanets, you have limited powers for prediction, because you haven’t built up a general theory about how everything moves together in an atmosphere and at extreme conditions. How does he react?”

Astronomers also spotted the planet KELT-20b, a giant exoplanet the size of the planet Jupiter, 400 light years away. in their study, which appeared in the astrophysical journal Letters. publish They found that this outer world is constantly receiving ultraviolet light from its parent star, creating a thermal layer in its atmosphere similar to Earth’s stratosphere.

While on Earth, the ozone layer protects us from harmful UV light by limiting high temperatures to a layer between 7 and 31 miles above Earth’s surface, the same is not the case with KELT-20b. The parent star of the exoplanet is working to form a strong inverted thermal layer by trapping metals in the atmosphere.<!–
