This is a picture of a part of Jupiter, the largest planet in the solar system. In this picture, you can see some of the 'belts' and 'zones' that make the planet instantly recognizable.
Included in the picture is the Great Red Spot, a giant storm that has been raging on Jupiter for at least 375 years or so, and probably much larger. The Great Red Spot is big enough to contain the entire Earth.
