Image labeled Fomalhaut system, Hubble Space Telescope. A grainy orange oval ring tilts slightly from upper right to lower left. At two o'clock, a white box outlines the ring's edge and white lines extend to a larger pullout box at lower right. Two spots inside the larger box are marked with dashed white circles and labeled cs1 2012 and cs2 2023. Inside the ring is a black circle with a white star symbol in the middle.

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.

Mosaic titled “Red Giant Echoes with Roman,” which shows 11 artist’s concepts of stars, including the Sun and 10 red giants of various radii against a black background. The illustrations are organized roughly into three rows with the grid size of the largest red giant star, located in the bottom right, the equivalent of two rows. Each star is depicted as a bright and blotchy orb. Starting with the mosaic’s smallest star, the Sun, in the top left corner and shifting to the right before moving to the next row, the illustrations become gradually larger and change from shades of light orange to red-orange. Each star’s radius is placed at the bottom of its grid. From left to right, the four light orange stars in the top row are listed with the following radii: Sun, Radius 1.0; Radius 6.3; Radius 7.0, and Radius 7.8. The second row has three orange stars and reads: Radius 8.8; Radius 9.7; and Radius 10.7. The third has four red-orange stars and reads: Radius 11.8; Radius 15.0; Radius 20.1; and Radius 33.7.

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.

At the center of the image is a comet that appears as a teardrop-shaped bluish cocoon of dust coming off the comet’s solid, icy nucleus and seen against a black background. The comet appears to be heading to the bottom left corner of the image. About a dozen short, light blue diagonal streaks are seen scattered across the image, which are from background stars that appeared to move during the exposure because the telescope was tracking the moving comet.

Two elliptical galaxies at upper right and lower left appear as fuzzy white ovals. At bottom center is a fuzzy purple blob outlined by a white box. White lines angle outward from the corners of the box to a blow-up of the purple blob. At the center is a white dot labeled HLX-1. The main image also has two bright stars with prominent diffraction spikes. The background of space is black, and is speckled with tiny white dots.

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.

A three-panel image, two at the top and one stretched across the bottom. At the top of the image is the title “Three Future Scenarios for Milky Way and Andromeda Encounter.” This title is extended over all three panels. In the top left panel, two spiral galaxies are widely separated against the black background of space. Beneath these galaxies are the words “Galaxies bypass at 1 million light-year separation.” In the top right panel, two face-on spiral galaxies are close together. Their spiral arms appear stretched toward each other. At the bottom of this panel are the words “At 500,000 light-years, dark matter provides friction that brings galaxies to a close encounter.” In the bottom panel, two spiral galaxies have collided, resulting in a broad X-shaped patch of milky white. Mottled clouds of dark brown dust are superimposed. At the bottom of this panel are the words “A 100,000 light-year separation leads to a collision.”
