We have taken a set of new discoveries from Juno Mission in NASA under the surface of the volcanic moon of the giant gas giant, IO, and in the world of hurricanes that play abundant cars in the Arctic Jovian.
Juno Reach Jupiter The system in 2016, but a failed fluctuation means that it is now stuck in a wide polar orbit approaching Jupiter and its moons every 53 days. However, during those flybys, Juno collected a set of high -quality data around Jupiter’s atmosphere, including in the planet columns, which have not been studied before in detail.
In the Arctic on Jupiter, there is a hat of the stratosphere, which was measured by Juno to be cooler than its surroundings by 52 degrees Fahrenheit (11 ° C). Around the polar cover there are jet currents blowing faster than 100 miles per hour (161 km per hour). Under the fog, the Arctic area is inhabited by one giant, a central hurricane, about 1864 miles (3000 km), surrounded by “groups” – eight smaller hurricanes ranging between 1,490 and 1790 miles land.

Juno has tracked the movement of this system of hurricanes in visible light and infrared (at the heat of the heat coming from the deepest inside the atmosphere) since 2016, using Junocam and Jovian Infrared Aurora Mapper (Jiram), respectively. These two residents showed that each of the eight hurricanes was drifting towards the electrode through a process called “Beta Drift”. The same process of hurricanes occurs on Earth, which is the result of the Coriolis power that interacts with the spinning wind pattern that belongs to each hurricane. However, on the ground, hurricanes do not get anywhere near the columns. This is because the closer they approach the cold and dry columns, the deplete of the warm, wet air that gives them energy. On Jupiter, the dynamics of the atmosphere vary, and this is not a problem. But once they reach the electrode, Jupiter’s hurricanes begin to collide with each other.
“These competing powers lead to the liar of hurricanes” from each other in a way that reminds us of springs in a mechanical system, “said Yahay Casbi, a participant in Juno from the Fayzman Institute of Science in Israel. statement. “This reaction not only proves the entire composition, but also leads to hurricane fluctuation around its central sites, because it slowly drifting west, in the direction of the clock, around the pole.”

Meanwhile, away from Jupiter’s atmosphere, Juno recently made a frequent fly of the deepest Juventus. IO The volcanic body in the solar system.
During Juno’s Flyby of IO on December 27, 2024, the spacecraft monitored what turned out to be Most of the active volcanic explosion I registered on IO. When Juno returned on March 2, the volcano was still spreading volcanic lava, and is expected to remain active during the Flyby in Juno, which is held on May 6 at a distance of 55300 miles (89,000 km) from IO’s roof.
But this lies below IO’s surface that got the science team in Juno. By combining the microwave radiation scale in the spacecraft (MWR) with Geram, scientists have been able to measure the underground temperature on IO, revealing the presence of magma’s underground flows.

“The Juno Science team loves to combine very different data collections of completely different tools and know what we can learn,” said Shannon Brown of NASA. “When we merged MWR data with infrared jerm pictures, we were surprised by what we saw: evidence of magma that still exceeds not to be strengthened after the bottom of the cooling dandruff in IO. In all lines of length and width lines, there were cold lava flows.”

Juno was previously I was excluded The presence of a large magma’s perimeter below the IO surface that can nourish volcanoes, but these increased flows, can explain how IO volcanoes erupt. The science team calculates that about 10 % of the surface surface of the moon has these cooling flows, which tells us more about how to transfer heat from IO from IO to its surface, allowing the world often to appear through lava flows above the ground.
Brown said: “IO volcanoes, lava fields and lava flows work like a radiator for the car, move with heat efficiently from the inside to the surface, and cool itself in the space vacuum.”
The latest results of Juno were presented on April 29 at the General Assembly of the European Union of Earth Sciences in Vienna.
