    A field full of small galaxies of all shapes against the blackness of space. A few bright white stars show 8 prominent diffraction spikes. A small galaxy at lower right is highlighted with a white box. A shaded triangle extends upward to the corners of a larger box showing a zoom in of the region. Two fuzzy, light blue blobs are at center, with a larger and brighter one at top. Just above the top blob is a white crosshair showing the location where a fast radio burst was detected.

  2. NASA Webb Explores Family Tree of Newly Discovered Distant Objects

    July 29, 2026Release ID: 2026-109 Missions: Webb, Hubble

    What do little red dots become as the universe ages?

    A rectangular image with thousands of galaxies of various shapes and colors on the black background of space. Some are noticeably spirals, either face-on or edge-on, while others are blobby ellipticals. Many are too small to discern any structure. One prominent foreground star at top center features Webb’s signature 8-point diffraction spikes. At upper right, a box shows a zoomed in portion of the image. The pullout features a spiral galaxy labeled “WISEA J123635.56+621424.2.” The galaxy has a bright yellow center and faint brown arms speckled with regions of blue that appear to wind clockwise around the galaxy’s core.

  3. Hubble Details Early Galaxy Transforming Neighborhood

    June 23, 2026Release ID: 2026-014 Missions: Hubble

    Researchers show that a galaxy’s young, tightly packed stars converted nearby gas from opaque to clear only 1.4 billion years after the big bang.

    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.

  4. NASA’s Webb Reveals Black Hole That Formed Before Its Galaxy

    May 27, 2026Release ID: 2026-110 Missions: Webb

    The first direct mass measurement from the early universe weighs in on the debate over the origins of supermassive black holes.

    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.

  8. 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.

    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.

    A black background of space, sprinkled with thousands of galaxies of all shapes and sizes. In the middle of the picture is an inset box showing a closeup of a pair of galaxies from the background. The larger galaxy is spiral-shaped. The other is spindle-shaped because the galaxy is seen edge-on. The smaller galaxy has a line that points to the words "supermassive black hole" connects to a bright white spot in the middle of it.

  13. NASA's Webb Reveals Distorted Galaxy Forming Cosmic Question Mark 

    September 04, 2024Release ID: 2024-128 Missions: Webb

    Astronomers are astounded by a rare cosmic alignment showcasing highly magnified star-forming regions in distant galaxies.

    Amid a field of galaxies, a repeated, elongated red galaxy forms a shape like the top of a question mark, with another galaxy positioned like the question mark’s dot. In each occurrence, another white, clumpy galaxy with an overall circular shape appears perched on top of the red galaxy. A very bright foreground galaxy appears to the right of the bottom curve of the question mark shape. To the lower right, among other galaxies, another occurrence of the galaxy pair appears, unaffiliated with the question mark shape.
