The magnetosphere of Jupiter is the cavity created in the solar wind by Jupiter's magnetic field.Extending up to seven million kilometers in the Sun's direction and almost to the orbit of Saturn in the opposite direction, Jupiter's magnetosphere is the largest and most powerful of any planetary magnetosphere in the Solar System, and by volume the largest known continuous structure in the Solar ...
During its Jupiter encounter, the probe made measurements of the planet's magnetosphere. [33] Since the probe had no cameras, no images were taken. In February 2004, the probe arrived again at the vicinity of Jupiter. This time the distance from the planet was much greater—about 120 million km (0.8 AU)—but it made further observations of ...
Jovian Infrared Auroral Mapper ( JIRAM) is an instrument on the Juno spacecraft in orbit of the planet Jupiter. It is an image spectrometer and was contributed by Italy. [1] Similar instruments are on ESA Rosetta, Venus Express, and Cassini-Huygens missions. [1] The primary goal of JIRAM is to probe the upper layers of Jupiter's atmosphere down ...
By May 2017, some of the first scientific analyses reported that JADE observed plasma coming up from the upper atmosphere of Jupiter into the magnetosphere. [5] Some auroral processes were compared to the ones on Earth, but there seemed to be other processes at work creating the auroras at Jupiter, according to the JADE project leader, in early ...
During this pass, the spacecraft studied Jupiter's magnetosphere, although it had no cameras to photograph the planet. The spacecraft passed by Jupiter six years later, this time at a much greater distance. [178] In 2000, the Cassini probe flew by Jupiter on its way to Saturn, and provided higher-resolution images.

The magnetosphere of Jupiter is the largest planetary magnetosphere in the Solar System, extending up to 7,000,000 kilometers (4,300,000 mi) on the dayside and almost to the orbit of Saturn on the nightside. [17] Jupiter's magnetosphere is stronger than Earth's by an order of magnitude, and its magnetic moment is approximately 18,000 times ...
The following is a chronology of discoveries concerning the magnetosphere. 1600 - William Gilbert in London suggests the Earth is a giant magnet. 1741 - Hiorter and Anders Celsius note that the polar aurora is accompanied by a disturbance of the magnetic needle. 1820 - Hans Christian Ørsted discovers electric currents create magnetic effects.
Io (Jupiter I) is the innermost of the four Galilean moons of Jupiter; with a diameter of 3642 kilometers, it is the fourth-largest moon in the Solar System, and is only marginally larger than Earth's moon. It was named after Io, a priestess of Hera who became one of the lovers of Zeus. It was referred to as "Jupiter I", or "The first satellite ...
