Jupiter's red eye is actually more commonly known as it's "Great Red Spot". It is a huge cyclonic storm, in fact a layer of storms on top of each other which have an enormous magnitude. It was originally discovered in 1831 and is believed to have persisted long before them, according to some speculations perhaps even thousands of years. It is believed to be a permanent feature of the planet. It is easily visible through telescopes and is believed to span 2-3 times the size of the Earth. It runs counter clock wise direction and it's dimensions are 24–40,000 km × 12–14,000 km.
