Astronomers have found a lava planet with supersonic winds and stone rains

One of the most extreme exoplanets discovered to date contains entire oceans of lava, according to a study by McGill University. Also here supersonic winds blow towards the icy night side, condensing into stone rain and snow.

Among the most extreme planets found outside our solar system are incandescent worlds that orbit so close to their star that regions are constantly melting. According to scientists from McGill University, York University and the Indian Institute of Science Education, the atmosphere and weather cycle at least one such exoplanet assumes evaporation and precipitation from rocks, supersonic winds at a speed of more than 5000 km / h and a magma ocean 100 km deep.

In the study, published in the Monthly Notices of the Royal Astronomical Society, scientists used computer simulations to predict conditions on K2-141b, an Earth-sized exoplanet. The extreme weather conditions predicted by their analysis show that hell is reigning on K2-141b, with rock melting and then precipitating on the night side. Two-thirds of the planet is illuminated, and this side is constantly facing the star and heated to 3000 C. On the night side, the temperature is constantly below -200 C.
