Neptune and Triton from Palomar
Explanation: How's the weather on Neptune? Tracking major weather patterns on the Solar System 's outermost gas giant can help in the understanding of global weather patterns here on Earth . Each summer for the past five years, Neptune has been imaged and major weather patterns studied. The latest picture, taken on September 15, is shown above in false color . Visible in pink near Neptune 's lower right is a new storm dubbed Annabelle that is several times larger than her terrestrial sister Isabel , a concurrent storm system that occurred here on Earth. Although Isabel lasted a few weeks, no one knows how long Annabelle will endure. On the upper right is Neptune 's largest moon Triton , an unusual moon that sports volcanoes that spew ice .
