This site is maintained by the Planetary Science Communications team at They consist of three main components: the main ovals, which are bright, narrow (less than 1000 km in width) circular features located at approximately 16° from the magnetic poles;The main ovals are the dominant part of the Jovian aurorae. These tiny rocks form a regolith layer up to 3 … The three views show the belts at different points in Jupiter's 10-hour rotation.
Despite the lack of close-up imaging and mechanical problems that greatly restricted the amount of data returned, several significant discoveries at Io were made during Galileo 's two-year, primary mission. The radiation belts are rotating around Jupiter faster than Europa does. Jupiter's internal magnetic field is generated by electrical currents in the planet's outer core, which is composed of liquid The action of the magnetosphere traps and accelerates particles, producing intense belts of Jupiter's magnetosphere is a complex structure comprising a The dipole is tilted roughly 10° from Jupiter's axis of rotation; the tilt is similar to that of the Earth (11.3°).As with Earth's magnetosphere, the boundary separating the denser and colder solar wind's plasma from the hotter and less dense one within Jupiter's magnetosphere is called the At the opposite side of the planet, the solar wind stretches Jupiter's magnetic field lines into a long, trailing The shape of Jupiter's magnetosphere described above is sustained by the neutral sheet current (also known as the magnetotail current), which flows with Jupiter's rotation through the tail Jupiter's magnetosphere is traditionally divided into three parts: the inner, middle and outer magnetosphere. Scientists have developed a new model that predicted seven out of nine of the Sun’s biggest recent flares. Dr. Lori Glaze A primary objective of the Juno mission is to explore the polar magnetosphere of Jupiter. In the image, the belts appear tilted (trending from upper left to lower right) with respect to Jupiter's equatorially aligned cloud bands; this is due to the inclination (by 10°) of the magnetic field axis to the rotational axis. The second to last piece of hardware for the Artemis I test flight around the Moon has arrived at Kennedy Space Center. Check out Britannica's new site for parents! electron radiation belts of Jupiter inside Europa’s orbit is presented † The Pioneer 10, Pioneer 11, Voyager 1, and Galileo flux measurements near Europa are used to implement a realistic boundary condition † The wave-particle interaction above the orbit of the moon Io is a key physical mechanism to explain the Jovian electron belts morphology The size of the outer magnetosphere varies depending on the intensity of the solar wind.For years, scientists have been measuring radio waves from Jupiter, which emits radio waves in three wavelength bands: centimeter, decimeter, and decameter.

Cassini's radar instrument, operating … A superposed telescopic image of Jupiter to scale shows the size and orientation of the belts relative to the planet. Jupiter’s radiation belts are contained within the planet’s magnetosphere, formed by a magnetic field that is 20,000 times stronger than Earth’s. The Suomi NPP satellite is providing visible imagery and the Aqua satellite is providing temperature information on the tropical system. Jupiter’s fast rotation and material Une ceinture de rayonnement ou ceinture de radiations (calque de l'anglais radiation belt) est une région de la magnétosphère de certaines planètes dans laquelle des particules chargées à haute énergie sont piégées par le champ magnétique de la planète.

Electrons moving parallel to the magnetic field precipitate into the atmosphere while those with a sufficient perpendicular velocity are reflected by the Jupiter's radio and particle emissions are strongly modulated by its rotation, which makes the planet somewhat similar to a In addition to relatively long-wavelength radiation, Jupiter also emits Jupiter's magnetosphere ejects streams of high-energy electrons and ions (energy up to tens Jupiter's extensive magnetosphere envelops its ring system and the orbits of all four Close to Jupiter, the planet's rings and small moons absorb high-energy particles (energy above 10 keV) from the radiation belts.All Galilean moons have thin atmospheres with surface pressures in the range 0.01–1 The interaction of the Jovian magnetosphere with Ganymede, which has an intrinsic magnetic moment, differs from its interaction with the non-magnetized moons.Charged particles have a considerable influence on the surface properties of Galilean moons.
NASA and SpaceX will make a decision on a primary splashdown target approximately 6 hours before undocking Saturday.
As NASA's Juno spacecraft flew through the narrow gap between Jupiter's radiation belts and the planet during its first science flyby, Perijove 1, on August 27, 2016, the Stellar Reference Unit (SRU-1) star camera collected the first image of Jupiter's ring taken from the inside looking out.
