Two images illustrating the changes in the high-altitude cloud structure on Neptune. The observations were made in the near-infrared (1.65 microns) using adaptive optics. This near-infrared image is primarily sensitive to high-altitude clouds, which appear bright against the darker disk. Adaptive optics allows ground-based telescopes to monitor Neptune's evolving weather systems and to use spectroscopy to probe different altitudes in its poorly-understood atmosphere. Neptune is the outermost of the giant planets in our solar system. It has the most dynamic and rapidly changing weather patterns.
