Saturn (WFC3/UVIS)

An image of Saturn on the black background of space. Image is labeled Saturn, Hubble Visible Light, August 22, 2024. Saturn’s horizontal bands appear pale yellow, with some bands towards the north and south pole having a light blue hue. The rings appear bright white, glowing slightly less than Webb’s infrared image. White dots, representing several of Saturn’s moons, are labeled Janus, Mimas, and Epimetheus. Mimas casts a small dark circular shadow onto Saturn’s surface.

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.

Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

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

Side-by-side comparison of Saturn observed at different wavelengths and times show how differently it appears in infrared, on the left, versus visible light, on the right. Left image is labeled Saturn, Webb Infrared Light, November 29, 2024. Right image is labeled Saturn, Hubble Visible Light, August 22, 2024.nIn infrared, Saturn has horizontal bands, with bands at the north and south poles appearing darker orange and lightening to tan as they approach the equator. The north and south poles glow a greenish-grey. The rings appear in an icy neon white. White dots, representing several of Saturnu2019s moons, are labeled Janus, Dione, and Enceladus.nIn visible, Saturnu2019s horizontal bands appear pale yellow, with some bands towards the north and south pole having a light blue hue. The rings appear bright white, glowing slightly less than Webbu2019s infrared image. White dots, representing several of Saturnu2019s moons, are labeled Janus, Mimas, and Epimetheus.

A wide look at Saturn and several of its moons on the black background of space. Image is labeled Saturn, Webb Infrared Light, November 29, 2024. Saturn has horizontal bands, with bands at the north and south poles appearing darker orange and lightening to tan as they approach the equator. The north and south poles glow a greenish-grey. The rings appear in an icy neon white. White dots, representing several of Saturnu2019s moons, are labeled Titan, Janus, Dione, and Enceladus. Titan is the largest dot, and appears at the far left of the image, some distance away from Saturn and the other moons.

A wider view of Saturn from NASA’s James Webb Space Telescope shows six of Saturn’s larger moons, including the largest, Titan, at far left.

Two side-by-side images of Saturn, with the left labeled Webb NIRCam, November 29, 2024 and the right labeled Saturn, Hubble WFC3/UVIS, August 22, 2024.nIn each image, Saturn has horizontal banding. Saturn is a darker orange in the NIRCam image, and a paler yellow in the WFC3/UVIS image. The planetu2019s rings are white in both, but glow brighter in the NIRCam image. White dots representing moons are labeled in both images.nAt bottom right of each image are compass arrows indicating the orientation of the image on the sky. The north arrow points to 12 ou2019clock, the east to 9 ou2019clock.nThe scale bar, at the bottom left of each image, reads 65,000 miles/100,000 km/16 arcsec and spans about one-third of each image. Below each image label is a color key showing which filters were used to create the image and which visible-light color is assigned to each filter. NIRCam filters are F164N in blue, F212N in cyan, F430M in green and F470N in red. WFC3/UVIS filters are F395N in blue, F502N in green, and F631N in red.
