Jupiter

Jupiter is one of the brightest objects in the sky and the largest planet in the solar system. It is a gaseous planet located among the outer planets. The most unique feature of Jupiter is the Great Red Spot. The Great Red Spot is larger than two Earths combined. This feature exists because it is a high pressure region and the cloud tops are much higher and colder than surrounding areas. Jupiter's surface clouds correlate with altitude.

In this photograph the emphasis was on Jupiter’s surface clouds. Although the image is in black and white, one can see the various brightnesses which correlates with Jupiter’s altitude. The darker clouds are areas of lower altitude and the lighter clouds are areas of higher altitude. The top and bottom of the planet consists of darker bands; near the center of planet is a fairly wide dark band. When one looks closely small wisps come from the wide dark central band. While the rest Jupiter appears to be lighter, small bands can be seen throughout which are a darker shade. Based on the image above and its distance on November 5, 2010 (4.2 AU), the diameter is approximately 180,000 km.
