During its 59th flyby of Jupiter on March 7, The Juno spacecraft captured detailed images of this object unusually hot. The images, which were obtained after a meticulous processing process, show not only this finding, but also reveal details that caught the attention of experts in Jupiter’s cloud and storm belts, including the Great Red Spot.

Which object close to Jupiter is the hottest in the Solar System according to NASA
The hottest object in the Solar System identified by NASA is Amalthea, a moon of Jupiter. This has the peculiarity of emit more heat than it receives from the Sun. The Juno mission captured images of Amalthea, which has a radius of just 84 kilometers and an irregular, potato-like shape. Observations suggest that its high temperature could be related to the electrical currents induced in its core while orbiting within Jupiter’s magnetic field. Another theory is thatThe heat comes from the tides generated by the intense gravity of this planet.
While capturing images, Juno was approximately 265,000 kilometers away. above the cloud tops of Jupiter, at a latitude about 5 degrees north of the equator. Scientist Gerald Eichstädt used raw data from the JunoCam instrument to create these detailed images, applying advanced processing techniques to improve their clarity.

What is the other NASA discovery related to Jupiter?
In addition to the discovery of Amalthea, NASA announced another significant discovery related to this planet. A recent study published in the journal Nature detected a wave-like motion in Jupiter’s magnetic field, a phenomenon that occurs approximately every four years. This discovery is crucial to understanding how Jupiter’s interior moves and changes, providing new insights into how planetary magnetic fields work.
The scientists observed that the Jupiter’s magnetic field varies with time, and these changes are fundamental to understanding its creation. Previous studies have shown that the movement of electrical fluids within the planet interacts with its magnetic field, causing variations that can be measured from the outside.

From this discovery, a new methodology emerged to study the interior of the largest planet, specifically in the metallic hydrogen region. In addition, changes in certain air currents were found near an area with a very strong magnetic field at Jupiter’s equator, leading experts to review past data that contained very different information.
