NASA’s Juno probe continues to beam back stunning pictures of Jupiter and its turbulent atmosphere. One of the latest shows the Great Red Spot in an image captured 21 December during the spacecraft’s most recent close approach. The photo also shows another large storm, dubbed Oval BA, that reached its current size when three smaller storms collided and merged together in 2000. Oval BA has changed shape over the years and changed from reddish brown to a more uniform white, according to NASA. This colour view is made up of three images captured when Juno was between about 23,800 miles to 34,500 miles above Jupiter’s cloud tops. The image was processed by citizen-scientists Gerald Eichstädt and Seán Doran.
