 Other atmospheric observations included a swirling dark oval of high atmospheric @-@ haze , about the size of the Great Red Spot , near Jupiter 's north pole . Infrared imagery revealed aspects of circulation near the poles , with bands of globe @-@ encircling winds , and adjacent bands moving in opposite directions . The same announcement also discussed the nature of Jupiter 's rings . Light scattering by particles in the rings showed the particles were irregularly shaped ( rather than spherical ) and likely originated as ejecta from micrometeorite impacts on Jupiter 's moons , probably on Metis and Adrastea . On December 19 , 2000 , the Cassini spacecraft captured a very @-@ low @-@ resolution image of the moon Himalia , but it was too distant to show any surface details .
