Explanation: What creates the colors in Jupiter's clouds? No one is sure. The
thick atmosphere of Jupiter [10] is mostly hydrogen [11] and helium [12] ,
elements which are colorless at the low temperatures of the Jovian cloud tops
[13] . Which trace elements provide the colors remains a topic of research
[14] , although small amounts of ammonium hydrosulfide [15] are one leading
candidate [16] . What is clear from the featured color-enhanced image [17] --
and many similar images -- is that lighter clouds are typically higher up than
darker ones. Pictured, light clouds swirl [18] around reddish regions [19]
toward the lower right, while they appear to cover over some darker domains on
the upper right. The featured image was taken by the robotic Juno [20]
spacecraft during its 14th low pass over Jupiter [21] earlier this year. Juno
[22] continues in its looping elliptical orbit, swooping near the huge planet
[23] every 53 days and exploring a slightly different sector each time around.
