Jupiter: 10 Years of OPAL Observations

Jupiter's bands of clouds present an ever-changing kaleidoscope of shapes and colors. There is always stormy weather on Jupiter: cyclones, anticyclones, wind shear, and the largest storm in the solar system, the Great Red Spot (GRS). Jupiter is covered with largely ammonia ice-crystal clouds on top of an atmosphere that's tens of thousands of miles deep. This nine-panel collage shows Hubble images of Jupiter taken under the OPAL (Outer Planet Atmospheres Legacy) program from 2015 to 2024, with approximately true color. OPAL tracks the Great Red Spot (GRS) and other notable changes in Jupiter's banded cloud structure of zones and belts over time.
