Hubble Marks 10 Years of Stunning Outer Planet Discoveries
The Hubble Space Telescope's Outer Planet Atmospheres Legacy (OPAL) program has provided a decade of detailed observations of the outer planets—Jupiter, Saturn, Uranus, and Neptune—revealing significant atmospheric changes and weather patterns. These observations have allowed scientists to track phenomena such as Jupiter's Great Red Spot, Saturn's seasonal ring spokes, Uranus' brightening polar cap, and Neptune's dark storms, enhancing our understanding of these distant worlds.
