  1. 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.

  2. 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.

  3. Hats Off to NASA's Webb: Sombrero Galaxy Dazzles in New Image

    November 25, 2024Release ID: 2024-137 Missions: Webb

    Powerful mid-infrared instrument resolves clumpy nature of dusty disk

    Image of a galaxy on the black background of space. The galaxy is a very oblong, blue disk that extends from left to right at an angle (from about 10 o’clock to 5 o’clock). The galaxy has a small bright core at the center. There is an inner disk that is clearer, with speckles of stars scattered throughout. The outer disk of the galaxy is whiteish-blue, and clumpy, like clouds in the sky. There are different colored dots, distant galaxies, speckled among the black background of space surrounding the galaxy.

  4. NASA's Webb Probes an Extreme Starburst Galaxy

  5. NASA’s Webb Reveals Intricate Networks of Gas and Dust in Nearby Galaxies

    February 16, 2023Release ID: 2023-104 Missions: Webb

    Young stars’ impact on galaxy evolution explored with PHANGS program

    A large galaxy takes up the entirety of the image. The image is mostly black with a bright, glowing oval core at the center. The core is mostly bright white, but there are also swirling, detailed structures that resemble water circling a drain. There is white and light blue colored dust that emanates from the core’s center, but it is tightly contained to the core. There is black space between the core and glowing dust of the outer oval rings. The rings are wispy and highlight filaments of dust around cavernous black bubbles. The dust in the outer rings contains dots that are navy blue, pinkish, reddish, and white. Throughout, there is also a smattering of background galaxies seen as small red and greenish dots.
