Saturn Storm by Ringshine
23.02.2006

Imaged on the night side of Saturn by the Cassini spacecraft, these swirling storm clouds are illuminated by ringshine - sunlight reflected from the gas giant's magnificent ring system. The storm (top) was actually spotted last month by amateur astronomers as it rotated across Saturn's day side and spans about 3,500 kilometers.

Blue jets appear blue in color and go from the tops of clouds to a height of about 50 kilometers.

Nobody knows what causes lightning. It is known that charges slowly separate in some clouds causing rapid electrical discharges (lightning), but how electrical charges get separated in clouds remains a topic of much research.

Telescopes are not very useful during lightning storms. Nevertheless, with lightning illuminating a dark landscape, the picturesque dome of the famous Kitt Peak 2.1-meter Telescope makes for a dramatic photograph. A passing car created the red and yellow streaks visible in the foreground.
