A tightly cropped Hubble view of a vast star-forming region known as the Trifid Nebula. The top left is bright blue. Brown and amber colors run from top right through the center in irregular, overlapping lines to the bottom-center. At bottom right, the view is almost black. Tiny, amber-colored stars appear throughout the scene. Toward the left there is a prominent brown shape that looks like a head with two horns. The left horn points left and is wavy. The right horn is triangular and points up. The brown dust continues, flowing down, as if along a back, and up toward the top right. A prominent line, about the same length as the left horn, appears below the middle of the body, and changes from orange to red. A small, separate semi-transparent pillar is left of the head. A few slightly larger, blue foreground stars with four diffraction spikes appear throughout.

Illustration shows four people at work within the outline of a large cloud. At center is a woman with a ponytail and dark skin whose hand is raised and close to the Roman Space Telescope body floating in space next to small white stars. The words, Roman Research Nexus, arc above the pair under the cloud outline. To her left are two other people, one with darker skin who is wearing headphones and writing and another with lighter skin, also with headphones, at a laptop. At right is a man with glasses, short wavy brown hair and light skin who is looking left, toward the telescope. In the background within the cloud shape, there are zeros and ones falling in the left third. At center is part of an outline of Roman’s camera’s field of view, and at right are representations of charts. Above the cloud is a darker background with simpler dark blue shapes. From left to right, they show a sphere following a path, a large spiral galaxy, a large ringed planet, and an object with diffraction spikes.

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.

A time sequence of three panels side by side. From left to right, the panels are labeled November 8, 2025; November 9, 2025; and November 10, 2025. This series of images from NASA’s Hubble Space Telescope of the fragmenting comet C/2025 K1 (ATLAS), or K1 for short, was taken over the course of three consecutive days. The sequence shows the progressive disintegration of the comet over this brief period. Each panel features several bright, fuzzy, blue, streaking lights in a diagonal line from the upper left to the lower right of a black background. In the first panel, four comet-like objects appear. The largest is the second from the upper left. In the second panel, the largest object has broken into two pieces. In the third panel, the pieces appear to be moving away from each other along the invisible diagonal line.

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.

In the image center, an opaque oval cloud of gray gas aligned from 1 o’clock to 7 o’clock hides a star. Two strong beams of light from the star emerge from large holes in both sides of the cloud, forming narrow cones extending toward 10 o’clock and 4 o’clock. The central cloud is surrounded by concentric, wispy shells of gas illuminated by the star’s light. The shells reflect extra light where they’re hit by the twin beams. A crowd of smaller stars with cross-shaped spikes over them surrounds the nebula on a black background.

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.
