Jupiter, the biggest mass giant of our Solar system. Juno that was launched at 2011 arrived at 2016 and proceeded to take pictures of Jupiter. New data has revealed some interesting details about Jupiter’s massive storm.

In the first two of the new studies, researchers explore the tiny variations in the tug of Jupiter’s gravity. The analysis suggests that the atmospheric storm bands swirling around the planet are not just surface features. Instead, they likely extend around 1,860 miles down.

As for Jupiter’s core, this has been an enduring mystery. The third new study, however, is starting to sort this out. The analysis suggests that the interior mass of Jupiter rotates as one single body, unlike its swirling surface. The findings also suggest that the core is likely in a liquid state and is not a solid.

The next revelation from Juno is a series of new photos from its Jovian Infrared Auroral Mapper, an instrument that was able to probe the weather at Jupiter’s poles as deep as 45 miles. The effort revealed an area of closely packed cyclones, some roaring at 220 miles per hour. At the north pole, eight cyclones circle around one central swirl while Juno found five of these whirls around the central cyclone of the south pole.

More interesting finds will likely be revealed about Jupiter as Juno orbits and scans the mass giant. Read more on smithsonianmag.
