The storm has been raging on Neptune, the eighth planet in our solar system. Its storm, known as the "Great Red Spot," has been around for at least 350 years. A storm known as the "Great Dark Spot" was recorded on the planet by Voyager 2 in the 1980s. But Neptune storms had never been tracked to understand their short lifespans. The dark spot was first seen on the planet at mid-southern latitudes.
