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 ...
Surrounding Jupiter's magnetosphere is a magnetopause, located at the inner edge of a magnetosheath—a region between it and the bow shock. The solar wind interacts with these regions, elongating the magnetosphere on Jupiter's lee side and extending it outward until it nearly reaches the orbit of Saturn. The four largest moons of Jupiter all ...
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 ...
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 ...
The aurorae on Saturn seem, like Earth's, to be powered by the solar wind. However, Jupiter's aurorae are more complex. Jupiter's main auroral oval is associated with the plasma produced by the volcanic moon Io, and the transport of this plasma within the planet's magnetosphere. An uncertain fraction of Jupiter's aurorae are powered by the ...
The Dungey cycle, officially proposed by James Dungey in 1961, [1] is a phenomenon that explains interactions between a planet's magnetosphere and solar wind. [2] Dungey originally proposed a cyclic behavior of magnetic reconnection between Earth's magnetosphere and flux of solar wind. This reconnection explained previously observed dynamics ...
The energetic particles coming from Jupiter's magnetosphere create bright auroral ovals, which encircle the poles. Unlike their terrestrial analogs, which appear only during magnetic storms, aurorae are permanent features of Jupiter's atmosphere. [28] The thermosphere was the first place outside the Earth where the trihydrogen cation (H +
