How does jupiter have a magnetic field

At 1, kilometers miles in diameter, Rhea is the second largest satellite of Saturn. Only Titan is larger. Bright wispy streaks cover one hemisphere of Rhea. Through the atmosphere of the southern hemisphere of Saturn rolls a large storm, seen here as a tight dark circle in the lower left of this image. Horizontal strands of other atmospheric formation Rolling Thunder. During its very close flyby of Enceladus on March 9, , Cassini took images of parts of the icy moon from different viewing angles, allowing the construction of stereo views.

These "3-D" views, Sliced-up Craters 3-D. This artist's conception of newly-discovered object 'Quaoar' - orbiting our Sun far beyond Pluto - shows how the tiny object compares to the size of North America. Another World. This image of Ceres is part of a sequence taken by NASA's Dawn spacecraft April 24 to 26, , from a distance of 8, miles 13, kilometers.

This image of Io was taken by the New Horizons spacecraft in The Tvashtar volcano is seen on top ejecting material km miles high.

This image shows two eruptions on the surface of Io taken by the Galileo spacecraft in The large eruption on the left edge of Io shows an eruption about km high. The eruption shown in the middle of the planet near the shadow line shows the Prometheus plume rising 75 km above the moon. Juno has braved that magnetic field during the probe's close approaches to the planet since arriving in July ; it skims about 2, miles 4, kilometers above the planet every 53 days over the course of elongated orbits.

A new paper, published Wednesday Sept. Like Earth, Jupiter's magnetic field has a primary north and south pole, close to the planet's actual poles as it rotates. But while the gas giant's south pole is relatively orderly, the planet's north pole has one narrow magnetic hotspot amid more chaotic patches of magnetic field, where positive and negative sections don't have concrete counterparts. And the planet has another big magnetic "south pole" close to the equator the researchers refer to this equatorial patch as a "great blue spot" in their paper, in contrast to the planet's swirling Great Red Spot storm.
