Gaseous yellow-orange filaments look like a rose seen from the side and tilted slightly from upper left to lower right, slightly higher than the center of the frame. Extending from the rose to upper left and lower right are gaseous outflows that appear as red lobes that have an overall shape of tall, narrow triangles with rounded tips. Each red triangle is made up of wavy, irregular lines. Dozens of stars are scattered across the field. One particularly bright white star with eight diffraction spikes is located at the top of the yellow rose. Another bright blue star with even more prominent diffraction spikes is to its lower left. The background of space is black.

An image titled “James Webb Space Telescope, Uranus, Discovery of Moon S 2025 U1”. At center is the planet Uranus, a blue globe with a large white spot occupying most of the planet. It’s surrounded by a series of rings that get brighter as you move outward. Beyond the rings are 14 labeled moons appearing as points of light. Just beyond the outermost ring at 10 o’clock, a faint moon is circled and labeled S 2025 U1. At far left, the brightest moon is labeled Miranda. Additional moons clockwise from Miranda are Puck, Cressida, Mab, Perdita, Desdemona, Belinda, Bianca, Ophelia, Rosalind, Portia, Cupid, and Juliet. At lower right are compass arrows with east pointing to 11 o’clock and north pointing to 2 o’clock. At bottom, a label reads NIRCam F150W2.

A section of the Cat’s Paw Nebula, a local star-forming region composed of gas, dust, and young stars. Four roughly circular areas are toward the center of the frame: a small oval toward the top left, a large circle in the top center, and two ovals at bottom left and right. Each circular area has a luminous blue glow, with the top center and bottom left areas the brightest. Brown-orange filaments of dust, which vary in density, surround these four bluish patches and stretch toward the frame’s edges. Small zones, such as to the left and right of the top-center blue circular area, appear darker and seemingly vacant of stars. Toward the center are small, fiery red clumps scattered among the brown dust. Many small, yellow-white stars are spread across the scene, some with eight-pointed diffraction spikes that are characteristic of Webb. A few larger blue-white stars with diffraction spikes are scattered throughout, mostly toward the top left and bottom right. In the top right corner is a bright red-orange oval.

An image of a nearby star and its vicinity. The star itself has been blocked out and its bright light has been removed, appearing black. A dashed circle with a star symbol at the center of the image marks the star’s location. A fuzzy blue disk surrounds the star. An orange spot, near the star and inside this disk around 2 o’clock, is identified as a planet orbiting the star. A fainter orange spot at the lower left edge marks a distant star.

Three panels, each showing a close-up near-infrared image of Jupiter’s north pole, in shades of orange. The planet is mostly dark. Thick, bright arcs and rings caused by auroras cover the pole. The center and right panels each show the aurora a few minutes later in time, as Webb’s field of view slowly scans over the planet.

What looks like a single large, bright star but is two shines with bright purple diffraction spikes at the center of a large, diffuse cylinder of gas and dust that is tipped to the right. At the center is a bright pink clumpy cloud that takes up about 25% of the view. The pink region has some holes. Beyond that are two large rings tipped at a 60-degree angle that mark the ends of the cylinder. They appear joined at top left and bottom right. The edges form shallow V-shapes that go inward. The rings appear orange at top left and bottom right, and are blue at bottom and center right. There is diffuse orange material around the body. The black background of space is speckled with tiny stars and galaxies mostly in blues and yellows. A bigger blue star with spikes is just below and to the left of the central stars, but it is slightly smaller. Areas Webb did not observe appear black along the top edges, a thin vertical near the nebula at top left, and at the bottom left and right corners.

A two-panel horizontal image. On the left is Neptune, as seen from the Hubble Space Telescope. It is a blue circle, tilted about 25 degrees to the left. There are white smudges at 7 o’clock and just above 5 o’clock. At the right is an opposing view of the planet, using data from Hubble and Webb. It is a multi-hued blue orb. There are white smudges in the same spots as the image on the left, but also at the center of the planet and at the top. There are cyan smudges vertically along the right side, with the top of the smudging more translucent than the bottom.

A large, black circle representing a black hole occupies the right third of the frame in this illustration. Thick, clumpy orange streaks arc above and below it, essentially surrounding it. The top arc extends down to the lower left and then curves around in front of the black hole to form a disk that is tilted toward the viewer. Near the inner edge of the disk, several bright, whiter spots have blue filaments looping above them, representing flares. The words “Artist’s Concept” appear in the bottom left corner in gray.

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.
