Scientists have detected a strange planet 390 light-years from EarthSo hot, that its sky is raining iron.
The daytime temperatures in this distant planet rise above 2400 ° C, which is high enough to dissolve minerals, and the winds traveling hundreds of miles per hour carry the particles of dissolved minerals to the cold night side, where they condense into clouds filled with iron droplets.
The new planet rains its iron sky only in the evening
“One could say that this planet is raining in the evening with iron,” said Professor David Ehrenrich, astronomer at the University of Geneva in Switzerland.
This strange phenomenon occurs because the strange, distant planet only shows one side of its side to its parent star, and its other side, which remains night or dark, remains cooler in complete darkness.
New findings can boost the search for extraterrestrial life, by helping to identify planets or moons that are likely to house them.
The international research team used the very large telescope of the European Southern Observatory (ESO) in the Atacama Desert in Chile to observe this giant planet in detail.
The planet is known as “WASP-76b”, and it is almost three times larger than Jupiter, and like the moon and its orbit around the earth, WASP-76b is “tidy locked”, which means that its rotation around its axis takes longer than the orbit around a star.
The planet receives thousands of times more radiation from its parent star than Earth receives from the sun, which are boiling molecules divided into atoms and vaporized minerals like iron in the atmosphere.
The intense temperature variation between the sides, day and night, results in strong winds, and this brings iron vapor from the extreme heat of the day to the cooler night side, where temperatures drop to about 1500 degrees Celsius.
According to the study, “WASP-76b” not only has different day and night temperatures, but has different night and day chemistry, as a new telescope scanner called “ESPRESSO” allowed to identify the chemical differences on this planet for the first time.
