A new theory has revealed that the mysterious ‘Y’ shape on Venus is the result of high intensity winds that are distorting a ‘wave’ of clouds to produce a stretched effect.

At first when the astronomers started taking ultraviolet images of Venus, they got baffled by the mysterious ‘Y’ shape that covered the entire planet.

The astronomers from the Institute of Astrophysics of Andalusia (IAA-CSIC) in Granada, Spain have proposed this theory in collaboration with the university of the Basque Country and the Institute of Astrophysics and Space Sciences of Portugal.

On Venus, strong winds move the upper atmosphere with 225 mph (360km/h) and encircle the planet in every four to five Earth days. The planet completes an orbit in around 243 Earth days, which means that the winds are much faster than the rotation speed of the planet.

The winds move with a constant speed at different latitude, but the winds that are nearer to the pole circles the planet faster as the circumference of the planet is smaller.

This finally results into ‘Y’ shape as the clouds at the top and bottom of the shape move faster.

The discovery can also prove helpful in revealing how such kind of processes take place on other slow-rotating bodies in the solar system.
