This image shows the planet Uranus set against the blackness of space. The planet appears as a smooth, bright cyan disc at the center, its atmosphere reveals soft, hazy tones of blue. Surrounding the planet is a vivid reddish glow, forming a diffuse halo that contrasts strongly with the cool blue of the planetary disc. Encircling Uranus are several thin, concentric rings, visible as pale gray arcs. Subtle variations in brightness can be seen across the planet’s face, with slightly brighter patches near the limb, hinting at atmospheric structure.

$Image shows a large spiral galaxy that that has a bright white center, with several lanes of reddish-brown dust and gas in between faint white arms. The galaxy takes up the center third of the frame. There are several thousand stars, some with diffraction spikes, scattered around the image. This image is labeled Hubble. A small box outlining an area at the center of the galaxy leads a pullout square at the top right. The image, labeled Webb, is dark with a white glowing oval at the center.$

A region of space is filled with stars and clumps of glowing orange and tan dust. A small portion of the sky at the center of the image is outlined with a white box. Lines extend from the corner of the box to the inset panel at the top right showing a magnified version of the outlined portion of the image. In the inset, there are smatterings of dim whitish-blueish stars and about seven glowing red orbs across the center in a line. Also across the center of the inset is a green glow. The background of the image is filled with stars and galaxies of various shapes and colors.
