NASA Juno reveals two massive storms on Jupiter's last flyby

Juno's latest Flyby shows two massive storms

This image of Jupiter's turbulent southern hemisphere was captured by NASA's Juno spacecraft as it completed its latest flyby of the giant gas planet on December 21, 2018.

This new perspective captures the remarkable Great Red Spot as well as a huge thunderstorm called Oval BA. The storm reached its current size when three small spots collided and merged in the year 2000. The Great Red Spot, which is about twice the width of the Oval BA, may have formed from the same process centuries ago.

Juno captured Oval BA in another image earlier in the mission on February 7, 2018. The turbulent regions around and even the shape of the storm have changed significantly since then. The Oval BA has changed even more in recent months, turning the color reddish to a more uniform white.

Juno took the three images used to produce this enhanced color vision on December 21, between 9:32 AM and 9:42 AM. At the time the images were taken, the spacecraft ranged from approximately 38,800 miles to 34,500 miles from the top of the planet's cloud, above southern latitudes, ranging from 49.15 to 59.59 degrees.

Citizen scientists Gerald Eichstädt and Seán Doran created this image using data from the spacecraft's JunoCam recorder.
