A beautiful storm ? In this image taken by our @NASAJuno spacecraft, a swirling storm somersaults through Jupiter’s South Equatorial Belt. This feature -- not to be confused with the planet’s iconic Great Red Spot -- is escorted by several smaller, reddish vortices above and to the left.

This natural color view offers an approximation of what Jupiter would look like to human eyes from Juno’s vantage point near the time of closest approach in its orbit. Jupiter’s stunning appearance is due to its atmosphere of colorful cloud bands and spots. The vivid red and orange hues are created by chemicals of uncertain composition called "chromophores." The image was taken July 15, 2018 as our spacecraft performed its 14th close flyby of Jupiter. At the time, Juno was about 4,900 miles (8,000 kilometers) from the planet's cloud tops, above a southern latitude of 36 degrees. Since 2016 Juno has been penetrating Jupiter’s deep, colorful zones and belts in a quest to answer fundamental questions about the gas giant planet's origin and evolution.
