NASA has discovered the hottest object in the solar system, a moon orbiting Jupiter

Jupiter revealed a Novel picture In a new flight he made NASA's Juno spacecraft On the largest planets in the solar system.

The ship captured the small one Jovian Moon AmaltheaWhich is characterized by being the reddest or hottest body in the solar system, During its 59th flyby of Jupiter on March 7 The two photos were obtained just this week.

The pictures provide a detailed view of Colored belts and storms of Jupiter, Including famous ones Big red spot. The Moon Amalthea is shaped like a potato, because it lacks mass to become a ball, and its radius is only 84 kilometers.

In 2000, NASA's Galileo spacecraft It revealed some surface features, including archaeological craters, hills and valleys. Amalthea orbits Jupiter within the orbit of Io, the innermost of the planet's four large moons, and takes 0.498 Earth days to complete one orbit.

Amalthea is the hottest body in the solar system The notes indicate this It emits more heat than it receives from the sun. This may be because it rotates within Jupiter's strong magnetic field, causing electrical currents to appear in the moon's core.

Alternatively, the heat could be due to tides caused by Jupiter's gravity. At the time the first of the two images was taken, it was the Juno spacecraft About 265,000 kilometers above Jupiter's cloud topsat a latitude of about 5 degrees north of the equator.

Citizen scientist Gerald Eichstadt created these images using raw data from the JunoCam instrument, applying processing techniques to improve the clarity of the images, NASA said.

Last week a recent study was published in the journal nature, Where scientists discovered A Wave-like movement in a magnetic field JupiterThis fact happens approximately every 4 years.

This discovery is very important for understanding how the interior of Jupiter moves and changes, and helps a lot in the study of space and how planets work. Planetary magnetic fields.

Experts pointed out that magnetic field Jupiter changes over time, and those Changes are key To understand how to create it.

The identified circular motion could be a direct indication of very internal motions that fuel the creation of Jupiter's magnetic field.

Previous studies have shown that the movement of electrical fluids inside the massive planet interacts with its magnetic field, which would cause changes that can be measured from the outside. By demonstrating this wave motion, scientists have a new way to study what is happening inside Jupiter, specifically in its interior. metallic hydrogen.

The scientific study also found changes in certain air currents near an area with a very strong magnetic field at the equator. Jupiter They are caused by the prevailing flux that greatly affects the magnetic field.

This fact has forced a revision of previous models, because the data do not agree as previously described.
