<\/a><\/span><\/div><\/div><\/div>Not only Jupiter, but also Saturn has its own band system, clearly visible in this image from August 25th.<\/p>\n
Unlike those of Jupiter, which are quite stable over time, Saturn's bands migrate slowly in latitude, following the point of maximum insulation (subsolar point). Note that the saturnian NEB (and SEB) is actually very large in latitude and splitted into 2 components (NEBn and NEBs).<\/p>\n

The next transit of Iapetus visible from Italy is foreseen on November 25, 2035.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
