A yellowish star is at the center of the image. It is surrounded by a mottled disk of gas and dust that transitions from bright yellow to darker orange as you move outward. The disk stretches from about 8 o'clock to 2 o'clock and is tilted so that the nearer side is toward the viewer.

This illustration is awash in bright blues, with only areas of the black background of space peeking out near the edges. Just above center is a large white spiral galaxy that is forming within a large cloud of blue gas. Its spiral arms twirl clockwise. Immediately around the galaxy’s edges are larger light blue dots. The gas appears thicker and brighter blue below the galaxy and toward the bottom left in what looks like a loose, extended column. Other wispy blue gas appears all around the galaxy, extending to every edge of the illustration. There are two additional spiral galaxies, though they are about half the size of the one at the center. They appear toward the top left and bottom right, and both are connected to regions of blue gas. Several bright knots dot the brightest blue areas near the center, and toward the top right. The background is clearer and more obviously black along a wider area at the left edge, a sliver along the top right, and in triangles toward the bottom right corner.

Illustration of a rocky exoplanet and its star. The star is in the background at the lower left and appears somewhat, but not significantly, smaller in the sky than the planet. It has a bright orange-red glow, and appears to have an active surface. The planet is in the foreground to the upper right of the star. The left quarter of the planet (the side facing the star) is lit, while the rest is in shadow. The planet has hints of a rocky, partly molten surface beneath the haze of a thin atmosphere. The boundary between the day and night sides of the planet is fuzzy.

Illustration showing a hazy blue planet against the black background of space. The planet is in the left side of the frame. The axis is tilted roughly 20 degrees counter-clockwise from vertical. The eastern side (right half) is lit by a star out of view and the western side (left half) is in shadow. The terminator (the boundary between the day and night sides) is fuzzy. There are white patchy clouds visible on the dayside, near the terminator, along the equator, that appear to be originating from the nightside.

A clumpy dome of blueish-gray clouds rises about a third of the way from the bottom. Above it, streaky, translucent red wisps brush upward to about halfway up the image. The top half of the image is the black background of space with one prominent, bright white star with Webb’s 8-point diffraction spikes. Additional stars and galaxies are scattered throughout the image, although very few are seen through the thick clouds at bottom and all are significantly smaller than the largest star.

Left: Messier 82 as imaged by NASA's Hubble Space Telescope. Hour-glass-shaped red plumes of gas are shooting outward from above and below a bright blue, disk-shaped center of a galaxy. This galaxy is surrounded by many white stars and set against the black background of space. A small square highlights the section that the image on the right shows in greater detail. White text at bottom reads "Hubble." Right: A section of Messier 82 as imaged by NASA's James Webb Space Telescope. An edge-on spiral starburst galaxy with a bright white, glowing core set against the black background of space. A white band of the edge-on disk extends from lower left to upper right. Dark brown tendrils of dust are scattered thinly along this band. Many white points in various sizes – stars or star clusters – are scattered throughout the image, but are most heavily concentrated toward the center. Many clumpy, red filaments extend vertically above and below the galaxy’s plane. White text at bottom reads "Webb."

At the center of the image is a nebula on the black background of space. The nebula is comprised of clumpy, red, filamentary clouds. At the center-right of the red clouds is a large cavernous bubble, and at the center of the bubble there is an opaque blueish glow with speckles of stars. At the edges of the bubble, the dust is white. There are several other smaller cavernous bubbles at the top of the nebula, including two tiny cavities at the top center of the image. There are thousands of stars that fill the surrounding area outside the nebula, most of them are yellow or white. At 11 o’clock and 6 o’clock there are extremely bright stars with 8 diffraction spikes. There are also some smaller, red stars and a few disk-shaped galaxies scattered across the image.

A rectangular image with thousands of galaxies of various shapes and colors on the black background of space. Some are noticeably spirals, either face-on or edge-on, while others are blobby ellipticals. Many are too small to discern any structure. One prominent foreground star at top center features Webb’s signature 8-point diffraction spikes. At lower right, a small region is highlighted with a white box. Vertical lines extend upward like a cone to the bottom corners of a larger box at upper right, showing a zoomed in version of the highlighted area. The pullout features a galaxy labeled GN-z11, seen as a fuzzy yellow dot. Above it is another galaxy, seen as a fuzzy red oval.

A three-panel image of a supernova remnant. The left panel is labeled “NIRCam” while the two right panels are labeled “MIRI M R S Argon two” (at top) and “NIRSpec I F U Argon six” (at bottom). At left, a mottled light pinkish-orange oval whose inner edge resembles a string of pearls. Within the oval is a dense blue-green cloud, shaped like a keyhole. Three stars with six-point diffraction patterns surround the oval. Above and below these structures, are very faint orange rings, which form a figure eight pattern. The center of the supernova remnant is surrounded by a white box with lines leading to the upper and lower right of the image, where two stacked panels show a bright orange ring with an orange dot in the middle. The upper panel is fuzzier and more blobby, while the bottom panel has more clearly defined edges around the ring and central dot.
