A new study has revealed a surprising secret for exoplanets known as "hot Jupiters" – the dark sides of these planets have "surprisingly equal" temperatures, suggesting that clouds can be made of minerals and rocks.
The study looks at 12 exoplanets and found that the night temperatures of these planets are about 800 degrees Celsius, suggesting that some kind of natural energy transfer is taking place.
"Atmospheric circulation models predicted that nighttime temperatures should vary much more than them," said the study's lead author, Dylan Keating, in a statement. "This is really surprising because all the planets we have studied receive varying amounts of radiation from their host stars, and the daytime temperatures among them vary by almost 1

Because of their distance from the sun, Jupiter's temperature measurements vary more in altitude. In the clouds, temperatures average about minus 234 degrees Fahrenheit, while near the center of the planet the temperature is bent 43,000 degrees Fahrenheit, NASA notes.
Keating and other researchers used data from the NASA Spitzer Telescope and the Hubble Space Telescope.
Researchers believe that "night clouds" may be the reason for such a rate.
"This result can be explained if most hot Jupiters have night clouds that are optically dense to longwave radiation and therefore radiate at the cloudiest temperature and gradually diffuse to planets receiving a higher incident The observations of the phase curve over a larger wavelength range are crucial for determining the extent of cloud cover and the composition of clouds in Jupiter's hot night points. "
According to NASA, more than 4,000 exoplanets have been discovered so far, and there are 3,000 more "candidates" that need additional surveillance to determine if they are genuine.
