Three rows show Webb images of the same region taken on three different dates. The top row is labeled August 19, 2024. The middle row is labeled September 16, 2024. The bottom row is labeled September 30, 2024. Each row shows two images split by a vertical black bar where there is no data. Each image is speckled with dozens of white stars, some showing Webb’s signature 8-point diffraction spikes, against the black background of space. The images also show tightly packed, glowing red filaments that resemble muscle fibers or wood grain. While the background stars are the same in every row, the filaments change noticeably. In the top row, the filaments extend horizontally from upper left to lower right. In the middle and bottom rows, the filaments extend from lower left to upper right, and seem to shift slightly downward in position, with the last the lowest.

A frame split horizontally down the middle. At left is a galaxy cluster and background galaxies, showing thousands of overlapping objects at various distances. The background is black. The galaxies’ colors vary, including white, pink, orange, and blue. Most galaxies appear as ovals or dots. Just above center is a bright white oversized oval, a supergiant elliptical galaxy. Around it are many thin, long orange or pink arcs. These are background galaxies that appear stretched and distorted. To the bottom right is the outline of a small box. On the right side is a zoomed in view of this area. There are two smaller circular outlines flanking a larger central oval outline, labeled Firefly Sparkle galaxy. Within it is a long line, pointing from bottom left to top right with 10 circular star clusters in pink, purple, and blue. The circled galaxy to the bottom left is labeled Companion 1 and looks like a bright red dot. At top right, the circled galaxy labeled Companion 2 is lighter red and surrounded by a red disk.

A two panel image. The top image is Webb’s view of the Sombrero galaxy, the bottom image is Hubble’s view. In the Webb view, the galaxy is a very oblong, blue disk that extends from left to right at an angle (from about 10 o’clock to 5 o’clock). The galaxy has a small bright core at the center. There is clear inner disk that has speckles of stars scattered throughout. The outer disk of the galaxy is whiteish-blue, and clumpy, like clouds in the sky. In the Hubble view, the galaxy is an oblong, pale white disk with a glowing core over the inner disk. The outer disk is darker and clumpy.

A two-panel image split down the middle vertically. At the left is the Vega disk as imaged by the Hubble Space Telescope. The disk is perfectly circular, and at the center is a black spot blocking out the bright glow of a star. Closer to the center, the disk is white. Radial striations extend out from the center, giving a ripple effect to the disk like the end of a sausage casing. The outer edge of the circular disk is blue. At the right, the Webb image of the disk is an orange colored, smooth, fuzzy halo. The inner disk is whiter toward the center, and there is darker lane between the inner disk and the more orange outer disk. The disk is also perfectly circular, with a black circle in the center due to lack of data from saturation.

Two spiral galaxies take the shape of a colorful beaded mask that sits above the nose. The galaxy at left, IC 2163, is smaller, taking up a little over a quarter of the view. The galaxy at right, NGC 2207, takes up half the view, with its spiral arms reaching the edges. IC 2163 has a bright orange core, with two prominent spiral arms that rotate counter clockwise and become straighter towards the ends, the left side extending almost to the edge. Its arms are a mix of pink, white, and blue, with an area that takes the shape of an eyelid appearing whitest. NGC 2207 has a very bright core. Overall, it appears to have larger, thicker spiral arms that spin counter clockwise. This galaxy also contains more and larger blue areas of star formation that poke out like holes from the pink spiral arms. In the middle, the galaxies’ arms appear to overlap. The edges show the black background of space, including extremely distant galaxies that look like orange and red smudges, and a few foreground stars.

An artist's concept looks down into the core of the galaxy M87, which is just left of center and appears as a large blue dot. A bright blue-white, narrow and linear jet of plasma transects the illustration from center left to upper right. It begins at the source of the jet, the galaxy’s black hole, which is surrounded by a blue spiral of material. At lower right is a red giant star that is far from the black hole and close to the viewer. A bridge of glowing gas links the star to a smaller white dwarf star companion immediately to its left. Engorged with infalling hydrogen from the red giant star, the smaller star exploded in a blue-white flash, which looks like numerous diffraction spikes emitted in all directions. Thousands of stars are in the background.

At center right is a compact star cluster composed of luminous red, blue, and white points of light. Faint jets with clumpy, diffuse material extend in various directions from the bright cluster. Above and to the right is a smaller cluster of stars. Translucent red wisps of material stretch across the scene, though there are patches and a noticeable gap in the top left corner that reveal the black background of space. Background galaxies are scattered across this swath of space, appearing as small blue-white and orange-white dots or fuzzy, thin disks. There are two noticeably larger points, foreground stars, with diffraction spikes: an orange-white point on the left, and a blue-white point in the top right.

Artist’s concept of spiral galaxy at the center of a much larger spherical halo of stars, with ground-based photograph pulled out to show details of the central core and spiral arms. View of the galaxy is halfway between face-on and edge-on, with disk oriented 45 degrees counter-clockwise from horizontal. Artist’s Concept: Galaxy core is whitish yellow, circled by a brownish purple disk. Grainy white halo enveloping the disk is dense and bright near the center, becoming more diffuse and fading out with distance from the main disk. Halo is mottled with a wispy cloud-like appearance, suggesting variations in density of stars. Halo covers an area of sky about 250 times greater than main disk. Photo: Telescope zoom into galaxy core and disk, outlined in yellow, shows brown dust lanes tracing spiral arms that wrap clockwise around fuzzy core; cloud-like patches of blue and red; star-like points of light of various size and brightness. Galaxy is 45 times larger in zoom than in illustration.

Hundreds of small galaxies against the black background of space. Several white spiral galaxies are near image center. Most of the galaxies are various shades of orange and red, and many are too tiny to discern a shape. A handful of foreground stars show Webb's six diffraction spikes.
