Night weather on Venus makes imaging difficult to observe. Because there is no sunlight to know it clearly.

However, astronomers have found a way by using infrared sensors on the Venus Akatsuki orbiter. This will reveal the first details of the nighttime weather of a nearby planet.

The study of Venus’ weather allows researchers to learn more about the mechanisms underlying Earth’s weather. Because Earth and Venus have a lot in common.

Infrared Imaging Detects Night Weather on Venus

So far, in the new study, researchers have known little about Venus’ conditions at night. The team found a new way to use infrared sensors. Located on Japan’s Venus climate orbiter, Akatsuki.

Launching space.com, in 2015 a probe arrived in orbit around the planet Venus. Then finally reveal the nighttime weather on Venus. Sensors found some strange wind circulation patterns and nighttime clouds.

Venus is actually in the livable zone, just like Earth. The surface is dense and has an atmosphere, there is even weather.

However, to understand Venus’s cucak, researchers must study the movement of the clouds using infrared light. Venus has the slowest rotation of any other planet in our Solar System, even though its atmosphere rotates rapidly. So that the occurrence of night and day on this planet lasts long enough.

Until now, only Venus’s daytime weather is easily observable. Because the weather at night is difficult to see even though using infrared. There are studies with infrared observations from the night side. However, it has not been able to clearly show the night weather on Venus.

To that end, the researchers switched to using Japan’s first explorer vehicle, the Akatsuki. In order to be able to monitor Venus at night, the probe has a special plan so that it does not require Sunlight.

Despite such a design, imagers have not been able to capture the night weather on Venus in detail. However, researchers can indirectly observe weather that is difficult to understand with new analytical methods.

Takeshi Imamura, a professor at the Graduate School of Frontier Science at the University of Tokyo, said there were small cloud patterns that dimmed immediately. Then can’t tell the difference from the background noise.

Researchers need to suppress noise to see the details. Unlike the other planets, Venus has an entire weather system that rotates so fast. So the researchers had to compensate for the movement to highlight the formation.

Venus Weather System

Venus has a rapidly rotating weather system. To overcome this movement or better known as super rotation, the researchers developed a new technique.

Super rotation is one of many significant meteorological phenomena. Of all the weather systems around the equator of Venus, the circulation is fierce from the east to the west.

Imamura and his team will explore the mechanism that supports this super rotation. They believe that the characteristics of the nighttime weather on Venus will help provide an explanation.

In the end the teams were able to observe north-south winds at night. These meridional circulations run in the opposite direction from their peers during the day. Without significant consequences, there would not be such a dramatic change.

This observation is expected to help the team build a more accurate model of the Venus weather system. So that it can reveal the weather of Venus and possibly the weather on Earth as well.

Venus Explorer Mission

The United States space agency, NASA also announced two new missions named DaVichi and Varieties that will explore Venus. Then the European Space Agency announced the Venus mission called Envision.

They will combine the mission with Akatsuki’s observation skills with Imamura and his team. The researchers used this new method and hope to reveal new details of weather on other planets, such as Earth or Mars. Missions from NASA and the European Space Agency will launch later this decade and early 2030s.

These observations are expected to resolve a number of long-standing questions about Venus’ weather that have yet to be answered. So that the night weather on Venus can be revealed, even regarding its geological history. (R10/HR Online)
