    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.

  7. NASA's Webb Digs into Structural Origins of Disk Galaxies

    June 26, 2025Release ID: 2025-121 Missions: Webb

    Scientists “excavated” disk galaxies across cosmic time to understand their formation history.

    Two mosaics of edge-on disk galaxies observed by the James Webb Space Telescope. Each mosaic has eight images, split in two rows. The mosaic at the top is titled “thin and thick disk galaxies.” The mosaic at the bottom is titled “thick disk only galaxies.” Each disk galaxy is centered within a square frame and lies against the black background of space. They appear as thin lines with a slight bulge in their centers. A few of the galaxies are horizontal or vertical, but many are angled diagonally. The thin and thick disk galaxies are overall whiter and brighter compared to the thick disk only galaxies, which are fainter and brown-orange. Text in the bottom right of each box lists the galaxy’s redshift. From left to right, the first row of the top mosaic reads z =0.12; z = 0.25; z = 0.45; and z = 0.72. The second row reads z = 0.21; z = 0.38; z =0.65; and z = 0.73. The top row of the bottom mosaic reads z = 0.73, z = 0.94; z = 1.25; and z = 2.63. The bottom row reads z = 0.91; z = 1.03; z = 2.13; and z = 3.01.

  8. NASA's Webb Rounds Out Picture of Sombrero Galaxy's Disk

    June 03, 2025Release ID: 2025-127 Missions: Webb

    Stellar light shines from iconic target in near-infrared

    Image of a galaxy on the black background of space. The galaxy is a very oblong, brownish yellowish disk that extends from left to right at an angle (from about 10 o’clock to 5 o’clock). Mottled dark brown patches rim the edge of the disk and are particularly prominent where they cross directly in front of the galaxy. The galaxy’s center glows white and extends above and below the disk. There are different colored dots, distant galaxies, speckled among the black background of space surrounding the galaxy. At the bottom right, there is a particularly bright foreground star with Webb’s signature diffraction spikes.

  9. NASA's Hubble Pinpoints Roaming Massive Black Hole

    May 08, 2025Release ID: 2025-015 Missions: Hubble

    Wandering black hole ate a star that got in its way.

    Six-panel illustration marked "Artist's Concept." The upper left panel shows the silhouette of supermassive black that is adrift inside a galaxy. The middle upper panel shows a yellow star drifting near the black hole. The three following panels show the star being shredded in bright white concentric streamers followed by a white explosion. the bottom right panel is an external view of the galaxy showing a bright white star-like object that is the site if the explosion as viewed in X-rays and visible light.

  10. Eye on Infinity: NASA Celebrates Hubble's 35th Year in Orbit

    April 23, 2025Release ID: 2025-013 Missions: Hubble

    Legendary space telescope redefined the universe.

    Composite shows four Hubble images in quarters. At top left is a crisp view of Mars in shades of orange, blues, and browns. At top right is planetary nebula NGC 2899, which is shaped like a single macaroni noodle, with its central torus appearing semi-transparent and blue and green, and its top and bottom edges in orange. At bottom left is a tiny portion of the Rosette Nebula. Very dark gray material shaped like a triangle takes up the center. At bottom right is barred spiral galaxy NGC 5335 with a milky yellow center that forms a bar surrounded by multiple blue star-filled spiral arms that wrap up counterclockwise.

  11. NASA's Webb Telescope Unmasks True Nature of the Cosmic Tornado 

    March 24, 2025Release ID: 2025-112 Missions: Webb, STScI

    Webb’s exquisite details reveal a chance, random alignment of a protostellar outflow and a distant spiral galaxy.

    Angled from the upper left corner to the lower right corner is a cone-shaped orange-red cloud known as Herbig-Haro 49/50. This feature takes up about three-fourths of the length of this angle. The upper left end of this feature has a translucent, rounded end. The conical feature widens slightly from the rounded end at the upper right down to the lower right. Along the cone there are additional rounded edges, like edges of a wave, and intricate foamy-like details, as well as a clearer view of the black background of space. In the upper left, overlapping with the rounded end of Herbig-Haro 49/50, is a background spiral galaxy with a concentrated blue center that fades outward to blend with red spiral arms. The background of space is speckled with some white stars and smaller, more numerous, fainter white galaxies throughout.

  12. NASA's Hubble Provides Bird's-Eye View of Andromeda Galaxy's Ecosystem

    February 27, 2025Release ID: 2025-009 Missions: Hubble

    A Swarm of Dwarf Galaxies Buzz Around Our Milky Way's Twin

    Telescope image with infographic overlays. At top left the text reads, Hubble Space Telescope, Survey of Andromeda's Satellite galaxies. A large field of galaxies take up the left three-quarters. This portion shows hundreds scattered across the black background of space. Most are tiny white dots. Thirty-six tiny galaxies are circled in yellow. Four have labels. From top to bottom, left to right: NGC 185, NGC 147, NGC 205 (M110), NGC 221 (M32). NGC 221 appears slightly lower than a larger, angled oblong galaxy, which is labeled Andromeda Galaxy (M31). Along the right is a column separated into four boxes, each a zoomed in portrait of the labeled galaxies. From top to bottom: NGC 185 looks like a dim blue haze that takes up most of the frame; NGC 147 like a small, very dim oval, with scattered dots nearby; NGC 221 is large and bright white, and takes up most of the box; NGC 205 is not quite as large as NGC 221, and is pinker, with larger dots throughout the frame.

  13. Straight Shot: Hubble Investigates Galaxy with Nine Rings

    February 04, 2025Release ID: 2025-006 Missions: Hubble

    Hubble’s high-resolution imagery allowed researchers to hone in on more of the Bullseye galaxy’s rings — and helped confirm which galaxy dove through its core.

    A large galaxy is at center, and a significantly smaller galaxy is to its immediate left. Both are set on the black background of space, which is dotted with a range of galaxies in different shapes and sizes, along with a few foreground stars.

  14. This Tiny Galaxy Is Answering Some Big Questions

    January 16, 2025Release ID: 2025-401 Missions: STScI

    Researchers used the James Webb Space Telescope to reveal patterns of star formation in an isolated dwarf galaxy.

    A concentration of bright blue stars occupies the bottom right corner of the image. At bottom center within them is a small blue bubble. The stars and bubble are part of a diffuse dwarf galaxy that extends beyond the image border. Background galaxies are scattered across the image, with some particularly prominent spirals located at upper left and upper right. The background of space is black.

  15. Newfound Galaxy Class May Indicate Early Black Hole Growth, Webb Finds

    January 14, 2025Release ID: 2025-101 Missions: Webb

    Scientists compile large sample of an unusual class of objects in an effort to connect the dots to the early universe.

    Six Webb images of little red dots are combined in a two-row mosaic. Each little red dot is centered within a square frame and lies against the black background of space. Each dot has a yellow-white circular core surrounded by a red, fuzzy ring. White text in the top left corner of each box lists the source’s name from the Webb surveys, and its redshift. From left to right, the top row reads CEERS 14448, z = 4.75; NGDEEP 4321, z = 8.92; and PRIMER-COS 10539, z = 7.48. The bottom row reads CEERS 20320, z = 5.27; JADES 9186, z = 4.99; and PRIMER-UDS 17818, z = 6.40.
