Astronomers solve the mystery of rotation of the strange planet Venus


According to the American “space” website, compared to the Earth, Venus rotates rapidly on its axis, where its surface takes 243 days from Earth to complete one rotation. 96 hours, an effect known as super-spin.

This mysterious phenomenon of circulation in the atmosphere appears not only on Venus, but also on Saturn’s largest moon, Titan.

Scientists analyzed data from the Japanese space probe Akatsuki, which has been orbiting Venus since 2015 to discover the secret behind it.

They focused on the super spin in the flower cloud layer, where the spin speed is higher, reaching about 245 miles per hour (395 km / h) in the area around the equator.

Scientists have developed a method to track Venus cloud movements to map the planet’s winds and the method for heat circulation in the atmosphere, based on ultraviolet images and thermal infrared data from Akatsuki.

This helped to give researchers a picture of how clouds are distributed across the cloud summit, which is about 42 miles (70 km) in height, and this, in turn, has helped them estimate the forces that maintain the superior spin atmosphere.

“Personally, our success in doing this was my biggest surprise,” study author Takeshi Horinouchi, planetary scientist at Hokkaido University in Sapporo, Japan, told

Scientists have discovered that Venus’ atmosphere got these clouds through thermal tides, which are differences in atmospheric pressure driven by solar heating near the equator on the planet.

They also found planetary waves in the atmosphere as well as widespread weather disturbances that worked against this influence of thermal tide.

Horinouchi revealed that the super-spin can balance the temperature differences between day and night, adding that future research can investigate how the super-spin of the atmosphere on Venus has remained stable over time.
