The study says the exoplanet K2-141b may have a magma ocean and be affected by supersonic winds

Researchers recently discovered the exoplanet K2-141b, which has extreme environments,media Slash Gear reported. It’s a hot world with orbits so close to the stars that some parts of the planet are likely to be magma oceans. Scientists from McGill University, York University and the Indian Institute of Science Education say the atmospheric and climate cycles on K2-141b are extreme.

The researchers say the planet is characterized by evaporation and precipitation of rocks, with supersonic winds ravaging the planet at speeds of more than 5,000 km/h and magma oceans up to 100 km deep. A study of the exoplanet was published recently, and scientists used computer simulations to predict the planet’s condition.

K2-141b is an Earth-sized exoplanet whose surface, ocean and atmosphere are made up of rocks. Scientists believe the extreme weather they have analyzed could permanently alter the planet’s surface and atmosphere over time. Two-thirds of K2-141b is in permanent daylight and belongs to a subset of rocky planets whose orbits are very close to stars. Proximity to a star locks a planet by tides, so it always faces the star on the same side.

The planet is a magma ocean of 3,000 degrees Celsius during the day and extremely cold below minus 200 degrees Celsius at night. Daytime temperatures are high enough to melt and vaporize rocks and form thin atmospheres in some areas. Extreme heat causes rock vapor to precipitate, just like the water cycle on Earth, but not water, but sodium, silica and silica, on K2-141b.

The evaporated rock was then blown into the cold night by the supersonic wind, and eventually the rock fell from the sky. The researchers point out that all rocky planets start in a melting world before cooling. K2-141b gives us a glimpse of what the Earth might look like before it cools down. Once the James Webb Space Telescope is launched in 2021, it will be investigated further.
