OPAL Jupiter Observations

A nine-panel collage showing Hubble images of Jupiter taken under the OPAL (Outer Planet Atmospheres Legacy) program from 2015 to 2024, with approximately true color. OPAL tracks the Great Red Spot (GRS) and other notable changes in Jupiter's banded cloud structure of zones and belts over time.

About the colours

These images are a composite of separate exposures acquired by the WFC3 instrument on the Hubble Space Telescope. Several filters were used to sample medium wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Blue: F395N, Green: F502N, Red: F631N
