Saturn (Webb NIRCam and Hubble WFC3/UVIS Compass Image)

👁 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. In 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 planet’s rings are white in both, but glow brighter in the NIRCam image. White dots representing moons are labeled in both images. At bottom right of each image are compass arrows indicating the orientation of the image on the sky. The north arrow points to 12 o’clock, the east to 9 o’clock. The 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.

These images of Saturn, captured by NASA’s James Webb and Hubble Spaces Telescopes, show compass arrows, scale bar, and color key for reference.

The north and east compass arrows show the orientation of the image on the sky. Note that the relationship between north and east on the sky (as seen from below) is flipped relative to direction arrows on a map of the ground (as seen from above).

The scale bar is labeled in miles, kilometers, and arcseconds. 

These images shows near-infrared and visible wavelengths of light with their color assignments. The color key shows which filters were used when collecting the light. The color of each filter name is the visible light color used to represent the light that passes through that filter.

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 NIRCam instrument on Webb and WFC3/UVIS instrument on Hubble. The color results from assigning different hues (colors) to a monochromatic (grayscale) image. In this case, the assigned colors for Webb are: Blue: F164N, Cyan: F212N, Green: F430M, Red: F470N, and for Hubble 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.
