Björn Jónsson took 12 high-resolution images of Jupiter’s great spot and compiled them into the great mosiac you see above.
This 12-footprint color mosaic of Jupiter’s Great Red Spot was composed of 24 images captured through orange and violet filters by Voyager 1 on March 4, 1979 at a distance of about 1.85 million km. The resolution is roughly 24 km/pixel in the “click to enlarge” version; for a full-resolution version at 18 km/pixel (2.5 MB), click here. Credit: NASA / JPL / color mosaic by Björn Jónsson
