Juno reveals the base of Jupiter and its large red dot

Only in 2016 did space exploration take place Juno Entered Around the circular path Around Thursday, The The largest planet in our solar system. Not less than five years from launch. Its purpose: to better understand what is playing underneath Clouds From Gas giant. After collecting data returned through years of research, researchers have begun to draw little by little the most accurate 3D image of the amazing, complex and violent process of its bold sound. Atmosphere.

Thanks to the microwave radiometer (MWR) Examine Juno, In particular, Astronomers Access valuable information about gas companies’ cloud tops. They can also explore Rotates Excites them up to 200 kilometers from the visible surface. Of these, the most famous is undoubtedly one that has fascinated researchers for at least two centuries: Big red dot.

In the secret of the big red dot

Recent results show that Storms Will be hotter than the height Gas Surrounding areas, with low atmospheric density. The Anti-storms – Turns in the opposite direction – Conversely, the altitude is cooler. That Storms It has become much deeper than astronomers thought. Some people only dive 100 kilometers under the clouds. But the Great Red Spot goes down to 350 kilometers! So these storms extend beyond areas where water condenses and clouds form. Down to any depth Light Of சோலைல் Can warm Jupiter’s atmosphere.

Complete this data Big red dot, In particular, The Astronomers Its gravity sought to classify the signature. The signature they believed could be detected due to the size and enormous mass of this massive meteorological image. They used it as an advantage Flyover Jupiter changes altitude at 650 million kilometers above Earth in July 2019 at Juno Speed 0.01 millimeters per second – this is 100 times slower than the speed of a snail and has a probe speed of 209,000 kilometers per hour. “Shocking Accuracy”, Marcia Parisi, JBL Researcher (Jet Propulsion Laboratory) From NASA, In a press release. Enough to help researchers provide a range of 500 kilometers to the depths of the Great Red Spot.

Details of Jupiter’s clouds

This big red dot is not the only one plotting astronomers in Jupiter’s atmosphere. The belts of white clouds and red areas are actually circling The giant planet. The Juno study has already clarified Holes Powerful forces moving in opposite directions between these bands sank for about 3,200 kilometers. At this time, data collected by the MWR show that ammonia is rising and falling in Jupiter’s atmosphere. Jet streams. Perhaps shed light on the mechanism behind the appearance of their creation.

“We found cyclic cells Northern Hemispheres And the “feral cells” that control most of us in the south Earth climate here, Explains Karen Duer, author of one Recent Articles In the Jupiter atmosphere. On Earth, there is one ferral cell per hemisphere. On Thursday, there are eight. Each is at least 30 times the size! “

Data also show that these cloud bands and relatively cloudless areas are subject to change up to 65 km below the water clouds. At shallower depths, they are brighter in the microwave range than their neighbors. But on deeper levels, it’s the opposite. Like what we observe on the edge of our oceans. Hence the name Jovicline for this position Analogy With Thermocline Terrain – The place where water temperature changes abruptly.

Stable polar storms

Recent figures studied by astronomers, Polar storms Juno had already discovered. The eight are arranged in an octagonal shape on the north pole side of Jupiter. Five forms a Pentagon above its South Pole. The Jovian Infrared Auroral Mapper Through the (Giram) study, it was possible to find that these atmospheric phenomena are highly resistant and stable.

“Its hurricanes oscillate around a state of equilibrium, Explains Alessandro Mura, a researcher at the National InstituteAstronomy From Rome (Italy). The behavior of these slow oscillations suggests that these hurricanes have deep roots. As the giram data indicates Hurricane On Earth, these hurricanes tend to move towards the poles. But the hurricanes at the center of each pole are pushing them back.
