Juno gives insight into Jupiter's epic winds

Jupiter is covered in violent, powerful winds that last hundreds of years

Clusters of cyclones churn over Jupiter

Researchers studying Jupiter using data and observations from the Juno spacecraft just released four new papers on their results, and I honestly can't say what's cooler: the science, or the jaw-dropping images.

The out-of-this-world images, which are derived from data collected from NASA's Juno spacecraft, show a multitude of massive cyclones on Jupiter, churning around the planet's north and south poles. They penetrate deep and last much longer than Earth's atmospheric processes.

By better understanding these strong jet streams and the gravity field, Mr. Kaspi said scientists can better decipher the core of Jupiter.

These astonishing science results are yet another example of Jupiter's curve balls and a testimony to the value of exploring the unknown from a new perspective with next-generation instruments.

This computer-generated image is based on an infrared image of Jupiter's north polar region that was acquired on February 2, 2017, by the Jovian Infrared Auroral Mapper (JIRAM) instrument aboard Juno during the spacecraft's fourth pass over Jupiter.

Until now, we only had a superficial understanding of them and have been able to relate these stripes to cloud features along Jupiters jets.

NASA's Juno Mission has revealed Jupiter's cyclone clusters mystery and showed that a certain amount of polygonally shaped cyclones that lye deep in 1,900 miles into the surface that are now visible thanks to NASA's efforts.

These discoveries and others are detailed in a series of papers published this month in the journal Nature. In the northern pole, eight cyclones perimeter around the pole revolve around another cyclone, while in the south pole five such cyclones move around a sixth. These poles are one of a kind in the solar system, being very close to one another, having very fast winds up to 350 kph, and being very large in size. By measuring this imbalance, which represents a change in the planet's gravity field, scientists have been able to establish that the winds reach a depth of around 3,000 kilometres; quite a bit more than previous estimates had calculated. Now, following the Juno gravity measurements, we know how deep the jets extend and what their structure is beneath the visible clouds. Finally, and perhaps most remarkably, they are very close together and enduring. It's like going from a 2-D picture to a 3-D version in high definition.

"By contrast, Earth's atmosphere is less than one millionth of the total mass of Earth", said Kaspi "The fact that Jupiter has such a massive region rotating in separate east-west bands is definitely a surprise".

Yohai Kaspi, co-author of the paper and a professor at the Weizmann Institute of Science, Israel, who led the research said: "That is much more than anyone thought and more than what has been known from other planets in the Solar System".

The other surprise? Juno detected that underneath its colorful, violent shroud, the planet rotates almost as a rigid body. A feature such as it is something that is like nothing else that has been observed so far in the solar system.

Tristan Guillot, a Juno co-investigator from the France University, said, "This is really an wonderful result, and future measurements by Juno will help us understand how the transition works between the weather layer and the rigid body below".
