A large, long portion of one of the spiral arms in galaxy M51. Red-orange, clumpy filaments of gas and dust that stretch in a chain from left to right comprise the arm. Shining cyan bubbles light up parts of the gas clouds from within, and gaps expose bright star clusters in these bubbles as glowing white dots. The whole image is dotted with small stars. A faint blue glow around the arm colors the otherwise dark background.

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.

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