  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. 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."

  9. '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.

  10. NASA's Hubble Finds that a Black Hole Beam Promotes Stellar Eruptions

    September 26, 2024Release ID: 2024-008 Missions: Hubble

    Nova Explosions in Double Star Systems Doubled Near Black Hole Jet

    An artist's concept looks down into the core of the galaxy M87, which is just left of center and appears as a large blue dot. A bright blue-white, narrow and linear jet of plasma transects the illustration from center left to upper right. It begins at the source of the jet, the galaxy's black hole, which is surrounded by a blue spiral of material. At lower right is a red giant star that is far from the black hole and close to the viewer. A bridge of glowing gas links the star to a smaller white dwarf star companion immediately to its left. Engorged with infalling hydrogen from the red giant star, the smaller star exploded in a blue-white flash, which looks like numerous diffraction spikes emitted in all directions. Thousands of stars are in the background.

  11. In Odd Galaxy, NASA's Webb Finds Potential Missing Link to First Stars

    September 25, 2024Release ID: 2024-133 Missions: Webb

    With its gas shining brighter than its stars, a strange galaxy found one billion years after the big bang may represent a previously-unknown phase of galactic evolution.

    A black background sprinkled with small, colorful galaxies. On the left, a third of the way down from the top of the image, a very faint dot of a galaxy is outlined with a white square and pulled out in a graphic to be shown magnified. In the pullout square to the right, the galaxy is a hazy white dot.

  12. NASA's Webb Provides Another Look Into Galactic Collisions

    September 18, 2024Release ID: 2024-132 Missions: Webb

    New infrared image highlights star formation triggered by merger-in-progress

    A pair of interacting galaxies. The larger of the two galaxies is slightly right of center, and composed of a hazy, bright, white center and a ring of gaseous filaments, which are different shades of red and orange. Toward the bottom left and bottom right of the ring are filaments of gas spiraling inward toward the core. At the top left of the ring is a noticeable gap, bordered by two large, orange pockets of dust and gas. The smaller galaxy to its left is made of hazy white gas and dust, which becomes more diffuse farther away from its center. To this galaxy's bottom left, there is a smaller, more diffuse gas cloud that wafts outward toward the edges. Many red, orange, and white galaxies are spread throughout, with some hazier in composition and others having more defined spiral patterns.

  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.

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