A side-by-side image showing both faces of Jupiter on the black background of space. At the top, left corner of the left-hand image is the label Jupiter. Centered at the bottom is the label "January 5, 2024." Jupiter is banded in stripes of brownish orange, light gray, soft yellow, and shades of cream, punctuated with many large storms and small white clouds. The largest storm, the Great Red Spot, is the most prominent feature in the left bottom third of this view. To its lower right is a smaller reddish anticyclone, Red Spot Jr. On the right-hand image, centered at the bottom is the label "January 6, 2024." This opposite side of Jupiter is also banded in stripes of brownish orange, light gray, soft yellow, and shades of cream, with many large storms and small white clouds punctuating the planet. At upper right of center, a pair of storms appear next to each other: a deep-red, triangle-shaped cyclone and a reddish anticyclone. Toward the far-left edge of this view is Jupiter's tiny orange-colored moon Io.
