The arrows show where clouds have formed or dissipated in the short time between the images. The smallest clouds are tens of kilometers across. The smallest resolved features are tens of kilometeres in size. In the false color image, the lower cloud deck appears bluish white, while the higher layer appears pinkish. The reddening near the edge of the planet in polar regions indicates a high stratospheric haze of methane, probably produced by magnetospheric particles.
Blue color means a transparent atmosphere.
Stratospheric haze exists at both latitudes, but is approximately 50 km higher near the poles. The low and mid latitude stratospheric haze are likely caused instead by photochemical reactions. Background information and educational context for the images can be found at SEPO , the best page on project Galileo. Galileo scientists are in the process of analyzing the data and preparing their results for publication. Galileo Mission scientists and engineers hope that you enjoy sharing the excitement of these images with us.
