  1. Webb Maps Full Picture of How Phoenix Galaxy Cluster Forms Stars

    February 13, 2025Release ID: 2025-107 Missions: Webb

    Discovery proves decades-old theory of galaxy feeding cycle.

    A galaxy cluster. The center of the cluster is bright white with short red jets that point toward the top right and bottom left, and several blue filaments that spread throughout the center. Outside the bright center is purple gas that is bright toward the center of the image and dimmer further from the center. There are contour lines overlayed in different colors. A key on the bottom indicates what each outline is representing. On the left side of the key, green irregular concentric lines shaped like a mountain on a topographic map are shown with the text cooling gas. Those same contours are placed overtop the center of the galaxy cluster. At the right side of the key, purple dashed lines are shaped in two ovals with the text jet-inflated bubbles. These oval outlines are place above and below the green contours at the center of the image.

  2. Found: First Actively Forming Galaxy as Lightweight as Young Milky Way

    December 11, 2024Release ID: 2024-116 Missions: Webb

    This galaxy, which is stretched and magnified, glitters with 10 distinct star clusters that formed at different times.

    Horizontal split down the middle. At left, thousands of overlapping objects at various distances are spread across this galaxy cluster. A box at bottom right is enlarged on the right half. A central oval identifies the Firefly Sparkle galaxy, a line with 10 dots in various colors.

  3. 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.

  4. Hubble Finds Weird Home of Farthest Fast Radio Burst

    January 09, 2024Release ID: 2024-001 Missions: Hubble

    Enigmatic Flash of Energy Comes from Merging Galaxies

    This image from the Hubble Space Telescope shows a field of blue, red, orange, yellow and white distant galaxies against the black backdrop of space. At image center, a white inset box labeled “Host galaxy of FRB 20220610A” zooms in on a tight group of several galaxies of various elliptical shapes (to the far right). The white arrow inside the inset box points to the host galaxy of the exceptionally powerful fast radio burst 20220610A detected inside this galaxy group.

  5. NASA's Webb, Hubble Combine to Create Most Colorful View of Universe

    November 09, 2023Release ID: 2023-146 Missions: Webb, Hubble

    The result: A vivid landscape of galaxies along with more than a dozen newfound, time-varying objects.

    A field of galaxies on the black background of space. In the middle, stretching from left to right, is a collection of dozens of yellowish spiral and elliptical galaxies that form a foreground galaxy cluster. Among them are distorted linear features, which mostly appear to follow invisible concentric circles curving around the center of the image.

  6. Webb Reveals Colors of Earendel, Most Distant Star Ever Detected

    August 09, 2023Release ID: 2023-132 Missions: Webb

    Observations hint at companion star

    A black background is scattered with hundreds of small galaxies of different shapes, ranging in color from white to yellow to red. Some galaxies, mostly the redder galaxies, are distorted, appearing to be stretched out or mirror imaged. Just a little bit above the center, there is a bright source of light, a star, with 8 bright diffraction spikes extending out from it. Below the star are several noticeably fuzzy white galaxies that resemble cotton balls – these are part of a galaxy cluster. To the lower right of the star is a particularly long, red, thin line stretching from one o’clock to 7 o’clock. This is the Sunrise Arc.

  7. Webb Spotlights Gravitational Arcs in 'El Gordo' Galaxy Cluster

    August 02, 2023Release ID: 2023-119 Missions: Webb

    New image reveals galaxy groups, smudges, and dusty distant objects.

    A black background is scattered with hundreds of small galaxies of different shapes, ranging in color from white to yellow to red.

  8. Webb Reveals Early-Universe Prequel to Huge Galaxy Cluster

    April 24, 2023Release ID: 2023-118 Missions: Webb

    Protocluster Confirmed, 650 Million Years after the Big Bang

    Telescope image with infographic overlays. Wide view of many galaxies colored orange, red and white. Most white galaxies have a hazy halo. A grouping of larger white galaxies appears below center. In the top half of the image, five small white squares highlight galaxies that would not stand out otherwise, with lines radiating from the small squares to a stacked column of five squares along the entire right side of the image, providing a zoomed-in view of specific galaxies, all appearing red.

  9. NASA's Webb Uncovers New Details in Pandora’s Cluster

    February 15, 2023Release ID: 2023-107 Missions: Webb

    Astronomers are "star struck" by Webb’s deep-field image of the megacluster

    A crowded galaxy field on a black background, with one large star dominating the image just right of center. Three areas are concentrated with larger white hazy blobs on the left, lower right, and upper right above the single star. Scattered between these areas are many smaller sources of light; some also have a hazy white glow, while many other are red or orange. Even without zooming in, different galaxy shapes are detectable, like spirals, ovals, and arcs.

  10. Hubble Finds that Ghost Light Among Galaxies Stretches Far Back in Time

    January 04, 2023Release ID: 2023-003 Missions: Hubble

    Orphaned Stars Were Lost into Intergalactic Space Long Ago

    Two side-by-side images showing dozens of galaxies of different colors, shapes, and sizes. At the center of each image is a cluster of galaxies within a ghostly blue light.

  11. Hubble Captures 3 Faces of Evolving Supernova in Early Universe

    November 09, 2022Release ID: 2022-054 Missions: Hubble

    Blast from the Past Caught in Episodes Due to Gravitational Lensing

    The left panel shows the portion of Abell 370 where the multiple images of the supernova appeared. Panel A, a composite of Hubble observations from 2011 to 2016, shows the locations of the multiply imaged host galaxy after the supernova faded. Panel B, a Hubble picture from December 2010, shows the three images of the host galaxy and the supernova at different phases in its evolution. Panel C, which subtracts the image in Panel B from that in Panel A, shows three different faces of the evolving supernova. Using a similar image subtraction process for multiple filters of data, Panel D shows the different colors of the cooling supernova at three different stages in its evolution.
