Scientists finally discover the reason behind the weird spin rates of Venus

It is already known that the planet Venus spins a bit weirdly and until now the researchers were unable to find out the span of one day on the planet. According to the previous estimations, a revolution of the Venus takes around two hundred forty-three Earth days with a varying rate of rotation. This varying rotation rate was never really explained.

A new study undertaken lately by a team of researchers has pointed out the reason behind the faster movement of the atmosphere of the planet while the planet itself moves comparatively slower. This new study was formulated by analyzing the pictures received from the Akatsuki spacecraft belonging to the Japanese space agency JAXA. According to the inferences of the study, the synergy between the faster moving atmosphere of Venus and the planet’s surface affect the velocity of the spin of the planet.

The data captured by the Akatsuki spacecraft depicted a massive atmospheric formation on the planet. According to the information provided by Akatsuki, the bow-like formation kept continuously appearing and disappearing as if following some sort of sequence. However, the formation never changed its position but stayed atop the mountains standing on the surface of Venus.  The scientists inferred that this peculiar atmospheric formation could be a faster moving “mountain wave.”

This phenomenon taking place in Venus was immensely tough for the researchers to study as it is not easy to image the surface of the planet both because of the constantly varying rotation rate of the planet as well as due to a permanent “thick cloud cover” over the surface of Venus. However, with this new study, the researchers have confirmed the mountain wave phenomenon taking place in Venus.  The researchers involved in the study explained briefly as to how the existence of the mountain wave affected the spin of the planet. The researchers said that the varying rotation rates of Venus were brought about by the wind’s varying direction while flowing against the mountains.

The author of the study, Thomas Navarro at the University of California, said in a statement, “Overall, a net force is exerted on the mountain, and the whole solid body follows.”

The observations of this new study were published in the Nature Geoscience journal on Monday 18th June.
