Thousands of galaxies appear across the black background of space. The galaxies range in size, from big blobs and larger face-on spirals to short lines and tiny dots. The galaxies appear in a variety of colors, including orange, white, pink, and blue. One prominent foreground star appears toward the lower right with several diffraction spikes. A white square highlights one tiny pinpoint of blue light in the top third, which is blown up in a box above it and labeled MXDFz4.4. The galaxy has a light blue core with some yellow and red blotches around its edges.

Comparison of three telescope images side by side. They are roughly spherical but pixelated, with more intense color saturation in the center. From left to right: smallest sphere is blue and labeled H2O, orange is larger and labeled CO2, and red is largest and labeled CO. A scale bar at the lower left is labeled 1300 km/1 arcsecond and is about one fourth of each of the three images. A compass at the lower right shows north pointing up to 12 o’clock, east pointing left to 9 o’clock, and a fainter arrow labeled to Sun pointing down to 8 o’clock.

Space telescope image showing hundreds of bright objects of different size, color, and shape on the black background of space. Colors range from white to deep red. Shapes include elliptical, spiral, dot-like, dash-like, and arcuate. Many of the large objects near the center of the image are fuzzy white, with bright white cores. Many smaller objects scattered throughout the image are pink to red. Three objects in the central part of the image are called out with small white boxes: A box labeled “C” at about 12 o’clock; one labeled “B” at 3 o’clock; and a box labeled “A” at 4 o’clock. Images of the three objects are enlarged in boxes running vertically along the right. From top to bottom these are labeled QSO1A, QSO1B, and QSO1C. At the center of each box is a tiny, circular red dot. QSO1A (top) is notably larger, brighter, and clearer than the other two. QSO1B, in the middle, is smallest and fuzziest, and is somewhat washed out by the light of a larger white object next to it.

A black square labeled “29 Cyg” at upper right. In the middle, a white star symbol is surrounded by a small blue trapezoid that widens from upper left to lower right of the star. The star is labeled with a capital A. The trapezoid indicates where the star’s light has been blocked by a coronagraph. To the star’s left beyond the blue trapezoid at 8 o’clock is a fuzzy white blob labeled with a lower-case b.

Side-by-side comparison of Saturn observed at different wavelengths and times show how differently it appears in infrared, on the left, versus visible light, on the right. Left image is labeled Saturn, Webb Infrared Light, November 29, 2024. Right image is labeled Saturn, Hubble Visible Light, August 22, 2024. In infrared, Saturn has horizontal bands, with bands at the north and south poles appearing darker orange and lightening to tan as they approach the equator. The north and south poles glow a greenish-grey. The rings appear in an icy neon white. White dots, representing several of Saturn’s moons, are labeled Janus, Dione, and Enceladus. In visible, Saturn’s horizontal bands appear pale yellow, with some bands towards the north and south pole having a light blue hue. The rings appear bright white, glowing slightly less than Webb’s infrared image. White dots, representing several of Saturn’s moons, are labeled Janus, Mimas, and Epimetheus.

Side-by-side images of the same nebula show how differently it appears in near-infrared, on the left, versus mid-infrared light, on the right. Left image is labeled NIRCam and the right is labeled MIRI. In near-infrared, the nebula’s outer bubble has a white edge and its inner clouds are orange, with a distinct dark lane cutting vertically through the center. Stars and background galaxies appear around the nebula and through the outer bubble. In mid-infrared, the outer bubble has a bluish tint and there is more material in the inner clouds, which are colored off-white. The vertical dark lane is still present but more interrupted and covered by the clouds. Material appears to be erupting out the top of the nebula, and this effect is mirrored to a lesser degree at the bottom, opposite end.

A wide field of view showing deep space, dotted with many small galaxies and a few foreground stars that display six diffraction spikes. One galaxy is highlighted with a magnified image in a graphic pull-out box in the lower right corner. The galaxy is labeled MoM-z14 and appears as a blurry yellow blob with a small red area at its top.

llustration labeled “artist’s concept” at right bottom corner. At left bottom corner, a partially illuminated, lemon-shaped exoplanet appears against a black background. This planet is most brightly illuminated at its elongated tip on its right side. On the left side, which is wider, the planet trails off into the darkness of the background. The planet is colored in varying, mottled shades of red, light pink, and fuchsia. Most of the pink occurs closest to the tip, while most of the fuchsia is at the top and bottom edges. At right top corner, a white beam emanates diagonally, oriented from 10 o’clock to 4 o’clock, from either side of a small, glowing, white star.

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.
