Jupiter and Its Two Red Spots June 2010 Jupiter and Its Two Red Spots Gemini North adaptive optics image of Jupiter and its two red spots (which appear white because this is a near-infrared image; in visible light they appear reddish).
Jupiter is the largest planet in the solar system. It has 67 moons which orbit around it. The spot in the lower left is the Great Red Spot, a giant high-pressure storm that has existed since at least the century.
