That Alien World that Rains Iron Just Got Even Weirder
Researchers have discovered a huge exoplanet with an extreme climate..
Using ESO’s telescope, an international team of astrophysicists found an exotic planet called WASP-76b, 640 light-years from Earth in the constellation Pisces. A giant the size of Jupiter revolves around a star and is in a tidal position (it takes the same amount of time to revolve around its axis as it does around a star), so it is always turned towards it with only one side.
Due to its proximity to the luminary, the planet receives thousands of times more radiation than the Earth from the Sun. This warms up the atmosphere on the day side above 2400 °C, which is sufficient to vaporize metals.
Time never receives light on the night side, then the temperature there drops to about 1500 °C. Due to the large temperature difference, the WASP-76b has strong winds that carry hot metal vapors to the cooler side, where they turn into iron rain..
Researchers identified this incredible phenomenon, since they condensed during the movement of the atmosphere, the boundaries of the evening and night sides of the planet were of greatest importance, and on the morning side they were practically nonexistent, therefore, during the movement of the atmosphere, they condensed.
Recall that recently scientists have also Mamnie why photons from other galaxies don’t reach Earth.
