Venus is known to be completely shrouded in dense clouds. To understand what's going on underneath,
In the new work, the authors have created a technique for observing the circulation of clouds over the night side of Venus: they have developed a technology to compensate for noise in images of Venus's clouds.

Preliminary data showed that at nightthe circulation of air masses in the planet's atmosphere changes direction by 180 ° C: from equatorial-polar during the day to polar-equatorial at night. Scientists believe that this phenomenon may enhance super-rotation.
We can finally watch the night winds fromnorth to south, known as meridional circulation. Surprisingly, they go in the opposite direction from their daytime winds. Such a dramatic change cannot happen without significant consequences. This observation could help us build more accurate models of the Venus weather system, which will hopefully resolve some long-standing questions about Venus's weather and possibly the weather on Earth.

This weather data on Venus can help scientists understand the geological history of the planet, as well as learn about how weather is formed on other planets.
