This image, taken with Hubble’s Advanced Camera for Surveys (ACS), shows the planetary nebula NGC 2022. The color composite was assembled from images taken in visible and infrared light. Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This new Hubble image of Jupiter, taken on June 27, 2019, reveals the giant planet’s Great Red Spot, and a more intense color palette in the clouds swirling in Jupiter's turbulent atmosphere than seen in previous years. The colors, and their changes, provide important clues to ongoing processes in Jupiter’s atmosphere. The bands are created by differences in the thickness and height of the ammonia ice clouds. The colorful bands, which flow in opposite directions at various latitudes, result from different atmospheric pressures. Lighter bands rise higher and have thicker clouds than the darker bands.
