Solar System
Saturn (WFC3/UVIS)
March 25, 2026 · NASA
This visible-light image of Saturn, captured Aug. 22, 2024, by NASA’s Hubble Space Telescope as part of its long-running Outer Planet Atmospheres Legacy (OPAL) program, reveals the planet’s softly banded atmosphere and bright ring system. Several of Saturn’s larger moons appear in the image. Janus is visible to the left of the planet along the rings, while Mimas appears closer to the disk as a small point of light, with its shadow superimposed on Saturn. On the right side of the image is Epimetheus, a moon that shares a unique co-orbital relationship with Janus.
The image helps scientists track seasonal changes, storms, and evolving atmospheric features on the ringed giant over time.
About the colours
These images were acquired by the WFC3/UVIS instrument on Hubble. The color results from assigning different hues (colors) to a monochromatic (grayscale) image. In this case, the assigned colors are: Blue: F395N, Green: F502N, Red: F631N
About the data
These images were created with Hubble data from proposal: 17294 (A. Simon).
