The distant moon in our solar system may reflect the seasons of the Earth, according to scientists, who also believe that it can be a candidate to find a nearby exotic life.
Scientists discovered a mysterious movement in its atmosphere.

Titan, the largest moon in Saturn, is home to the sprawling rivers, liquid methane lakes, ice rocks and dunes of coffee grains.
She even has the ocean hiding under its surface.
About 746 million miles (1.2 billion km) away from Earth, the distant moon is believed to have rain clouds just like Earth.
Unlike the seasons on Earth, Titan has a much longer seasonal cycle, where each year reaches the moon to nearly three decades on our planet.
Despite the brutal cold temperatures, whose average is about -179 ° C (-290f), this strange strange world appears to have life -long organic components.
Titan is the only moon in our solar system with an important atmosphere, making it a great candidate for exploration.
The Dragonfly mission of $ 3.35 billion from NASA (2.48 billion pounds) will explore to Saturn to explore the possibility of previous or current water -based life, especially in the under the surface and liquid tanks.
The task passed the critical design review – which means that engineers can start building a robot similar to a helicopter before its launch scheduled in July 2028.
Dragonfly, who was officially chosen as a viable task in 2019, is expected to arrive at some time in 2034.

“Strange” movement
In late May, the researchers found that Titan's blurring atmosphere fluctuates like the gyroscope, which is in line with its seasons, instead of spinning in line with its surface.
The “strange” movement was discovered after analyzing the archived infrared data collected by the Cassini probe.
“The behavior of Titan's tilt in the atmosphere is very strange,” said Dr. Lucy Wright, a post -PhD researcher at Bristol University.
“It seems that the Joe Titan behaves like gyroscope, and settles himself in space.
“We believe that some events in the past may have removed the atmosphere from the axis of rotation, causing it to be softened.
“And the most interesting thing, we found that the size of this mile changes with the seasons of Titan.”

But understanding how the atmosphere fluctuates with the seasons is crucial to calculating the path of landing in the dragon.
Rotorcraft will be implemented by the fast Titan winds that descend in the atmosphere.
The wind can be in the upper atmosphere for a storm, with up to 270 miles per hour (430 km / hour).
Near the surface, however, the wind is much weaker.
The planet's tilt affects how the useful load of Dragonfly – a group of scientific tools designed to search for an exotic life – through the air.
Therefore, the movement's movement in the atmosphere of engineers can help better predict the location of the fans on the moon.

Food to think
There seems to be a lot of organic materials in Titan to support LifeForms Alien, according to a study published in the Journal of Planetary Science last month.
It is believed that its lakes and surroundings are under the surface of the earth believe that it is 300 miles depth, filled with cold methane, olive and ethane – an organic substance.
“There was this feeling that because Titan had such abundant organic materials, there is no shortage of food sources that could preserve life,” said Antonin, of the University of Arizona and the newspaper’s author in a statement.
The world exceeds the oil reserves of the Earth.
However, scientists are still skeptical, and while Titan can shelter life, it is likely to be only a small amount.
“We point out that not all of these organic molecules may constitute food sources, the ocean is really large,” one of the information owners added.
“There is a limited exchange between the ocean and the surface, where all these organic materials, so we discuss a more accurate approach.”
