A volcanically active planet is shown in closeup at the left side of the image with glowing eruptions and lines of lava on the surface. To the right and in the distance is a faint blue glowing ball representing the more massive planet in the system.

Sixteen frames from Voyager 1's flyby of Jupiter in 1979 were merged to create this image. Jupiter's Great Red Spot is visible in the center. Jupiter's moon Europa can be seen in the foreground at the bottom left of the image.

The frame is a horizontal rainbow of color on a grid. Shadows of molecules can be seen through the light as well as the jagged peaks and troughs of spectral lines.
