  1. 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.

  2. 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.

  3. NASA's Hubble Traces Hidden History of Andromeda Galaxy

    January 16, 2025Release ID: 2025-005 Missions: Hubble

    Panorama of Nearest Galaxy Unveils Hundreds of Millions of Stars

    The Andromeda galaxy, a spiral galaxy, spreads across the width. It is tilted nearly edge-on to our line of sight so that it appears as an extreme oval on its side. The borders of the galaxy are jagged because the image is a mosaic of smaller, square images. The outer edges are blue, while the inner two-thirds are yellowish with a bright, central core. Dark, dusty filamentary clouds wrap around the outer half of the galaxy’s disk. At 10 o'clock, a smaller dwarf elliptical galaxy forms a fuzzy, yellow blob. Hubble's sharp vision distinguishes about 200 million stars within the image. The background of space is black. There are what appears to be steps toward the bottom, mainly toward the middle, which indicates where no data were taken.

  4. NASA's Webb Finds Planet-Forming Disks Lived Longer in Early Universe

    December 16, 2024Release ID: 2024-135 Missions: Webb, Hubble

    New data confirms Hubble finding and refutes current theories of planet formation in universe’s early days.

    The center of the image contains arcs of orange and pink that form a boat-like shape. One end of these arcs points to the top right of the image, while the other end point toward the bottom left. Another plume of orange and pink expands from the center to the top left of the image. To the right of this plume is a large cluster of white stars. There are various other white stars and a few galaxies of different sizes spread throughout the image. Ten, small, yellow circles overlaid at various points across the image indicate the positions of the ten stars surveyed in this study.

  5. NASA's Hubble Sees Aftermath of Galaxy's Scrape with Milky Way

    November 14, 2024Release ID: 2024-031 Missions: Hubble, STScI

    Encounter Blew Away Most of Smaller Galaxy's Gaseous Halo

    A whitish, whirlpool-like galaxy at middle of top edge, and a tadpole-shaped structure sweeps from left to right across lower half. A label pointing to outer, left of galaxy reads "Earth." Faint, purple haze labeled "Milky Way Halo" surrounds galaxy and stretches to graphic's edges. The tadpole-shaped object is the Large Magellanic Cloud, or LMC, with its own halo and streaming tail. Semi-circular, progressively darker layers of purple labeled "LMC Halo" surround the LMC, which appears roughly circular, with a central, light yellow bar. Cloud-like features sprinkled with white specks surround this bar. Trailing the LMC is a large, tail-like feature labeled "Stream." At the bottom left corner of graphic are several small, bright points of light labeled "Quasars." Three light blue lines point from the label "Earth" through the LMC's halo, and to three corresponding quasars. At the bottom, right corner is the label "Artist's Concept."

  6. 'Blood-Soaked' Eyes: NASA's Webb, Hubble Examine Galaxy Pair

    October 31, 2024Release ID: 2024-136 Missions: Webb, Hubble, STScI

    By teaming up, these two space telescopes have delivered the highest resolution image of IC 2163 and NGC 2207 to date in a combination of mid-infrared, visible, and ultraviolet light.

    Two spiral galaxies take up almost the entire view and appear to be overlapping. The galaxy at left, IC 2163, is smaller and more compact than the galaxy at right, NGC 2207. The black background of space is dotted with foreground stars and extremely distant galaxies.

  7. NASA's Roman Space Telescope to Investigate Galactic Fossils

    August 29, 2024Release ID: 2024-205 Missions: STScI, Roman

    Scientists will study nearby galaxies to uncover galactic formation history and dark matter

    Artist’s concept of spiral galaxy at the center of a much larger spherical halo of stars, with ground-based photograph pulled out to show details of the central core and spiral arms.

  8. NASA's Hubble Traces Dark Matter in Dwarf Galaxy Using Stellar Motions

    July 11, 2024Release ID: 2024-017 Missions: Hubble

    The telescope's longevity is an asset in gaining clarity about the universe's invisible glue.

    At left is the Digitized Sky Survey view of the Draco dwarf galaxy. Many yellow, blue-white, and white stars are dispersed across the black background of space. They vary in shape and size, though most resemble small, circular points of light. Larger stars, some with four diffraction spikes, are scattered infrequently across the field of view. A thin, light brown oval highlights the area of interest, which contains two small white squares in its center. The area of each square is magnified at right, showing views captured by the Hubble Space Telescope. The top right square reveals a black patch of space with many small points of light and a large, four-point diffraction spike toward the left. The bottom right square shows a black patch of space filled with small points of light, some with diffraction spikes.

  9. NASA Releases Hubble Image Taken in New Pointing Mode

    June 18, 2024Release ID: 2024-026 Missions: Hubble

    The image represents one of the first observations taken with Hubble since transitioning to the new pointing mode, enabling more consistent science operations.

    At center is a new Hubble telescope image of the nearby galaxy NGC 1546. The galaxy's orientation gives us a good view of dust lanes from slightly above and backlit by the galaxy's core. This dust absorbs light from the core, reddening it and making the dust appear rusty-brown. The core itself glows brightly in a yellowish light indicating an older population of stars. Brilliant blue regions of active star formation sparkle through the dust. Several background galaxies are also visible, including an edge-on spiral just to the left of NGC 1546.

  10. NASA's Webb Depicts Staggering Structure in 19 Nearby Spiral Galaxies

    January 29, 2024Release ID: 2024-105 Missions: Webb

    A new treasure trove of Webb images has arrived! Near- and mid-infrared images show off every facet of these face-on spiral galaxies.

    Nineteen Webb images of face-on spiral galaxies are combined in a mosaic, some within squares, and others horizontal or vertical rectangles. Galaxies' spiral arms appear in shades of orange, and many of their centers have light blue hazes.

  11. NASA's Hubble Presents a Holiday Globe of Stars

    December 20, 2023Release ID: 2023-020 Missions: Hubble

    Dwarf Irregular Galaxy Springs to Life with Dazzling Newborn Stars

    A collection of stars and galaxies fill the scene against a dark background. The image is dominated by a dense collection of stars which make up the irregular galaxy UGC 8091. The stars span a variety of colors, including blue and orange, with patches of blue occupying the central part of the galaxy. There are also visible circular regions of red/pink gas within the galaxy.
