Swirling Neptune (VIDEO) University of Arizona This video is under embargo. Please login to access this video. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Caption By tracking atmospheric features on Neptune, a UA planetary scientist has accurately determined the planet's rotation, a feat that had not been previously achieved for any of the gas planets in our solar system except Jupiter. In this animation, the viewer takes the perspective of an object circling Neptune matching its rotational speed, much like a geostationary satellite hovering above the same spot. Only then does the giant gas planet reveal the movements of its features relative to each other, often in opposite directions. Credit E.
