  1. NASA's Hubble Detects First-Ever Spin Reversal of Tiny Comet

    March 26, 2026Release ID: 2026-012 Missions: Hubble

    Outgassing jets slowed the comet’s spin and restarted it in the opposite direction

    Illustration, close up of rocky, potato-shaped body of a comet with detailed, cratered surface at the bottom right. A glowing ray emanates from the rocky surface like sunlight through clouds. It extends from the comet’s surface across the image to the left. This represents water ice being vaporized by the heat of the Sun. There are small bright dots within the ray, representing fragments of the comet. The words Artist's Concept appear at the bottom left.

  2. NASA Webb, Hubble Share Most Comprehensive View of Saturn to Date

    March 25, 2026Release ID: 2026-117 Missions: Webb, Hubble

    Infrared and visible observations show layers and storms in the ringed planet’s atmosphere

    Side-by-side comparison of Saturn observed at different wavelengths and times show how differently it appears in infrared, on the left, versus visible light, on the right. Left image is labeled Saturn, Webb Infrared Light, November 29, 2024. Right image is labeled Saturn, Hubble Visible Light, August 22, 2024. In infrared, Saturn has horizontal bands, with bands at the north and south poles appearing darker orange and lightening to tan as they approach the equator. The north and south poles glow a greenish-grey. The rings appear in an icy neon white. White dots, representing several of Saturn’s moons, are labeled Janus, Dione, and Enceladus. In visible, Saturn’s horizontal bands appear pale yellow, with some bands towards the north and south pole having a light blue hue.

  5. NASA’s Hubble Unexpectedly Catches Comet Breaking Up

    March 18, 2026Release ID: 2026-010 Missions: Hubble

    Researchers’ long-sought experiment happened serendipitously.

    A time sequence of three panels side by side. From left to right, the panels are labeled November 8, 2025; November 9, 2025; and November 10, 2025. This series of images from NASA’s Hubble Space Telescope of the fragmenting comet C/2025 K1 (ATLAS), or K1 for short, was taken over the course of three consecutive days. The sequence shows the progressive disintegration of the comet over this brief period. Each panel features several bright, fuzzy, blue, streaking lights in a diagonal line from the upper left to the lower right of a black background. In the first panel, four comet-like objects appear. The largest is the second from the upper left. In the second panel, the largest object has broken into two pieces. In the third panel, the pieces appear to be moving away from each other along the invisible diagonal line.

    The elusive object dubbed CDG-2 may be composed of 99% dark matter.

    Two images side by side. At left, a field of space with a dozen white foreground stars and small, yellow background galaxies. An area at center is outlined with a dashed red circle surrounded by a white box. Lines extend from the box to a pullout at right containing faint, grainy white light surrounded by a red circle labeled “Candidate dark galaxy – diffuse emission.” Four white dots are circled in blue and labeled globular clusters.

  7. NASA's Hubble Captures Light Show Around Rapidly Dying Star

    February 10, 2026Release ID: 2026-008 Missions: Hubble

    Interplay of shadow, light, and dust hints at processes shaping enigmatic nebula

    In the image center, an opaque oval cloud of gray gas aligned from 1 o’clock to 7 o’clock hides a star. Two strong beams of light from the star emerge from large holes in both sides of the cloud, forming narrow cones extending toward 10 o’clock and 4 o’clock. The central cloud is surrounded by concentric, wispy shells of gas illuminated by the star’s light. The shells reflect extra light where they’re hit by the twin beams. A crowd of smaller stars with cross-shaped spikes over them surrounds the nebula on a black background.

    New findings include galaxy mergers and "jellyfish" galaxies.

    Six Hubble images of distorted galaxies are organized in a two-row mosaic.

  9. NASA Hubble Helps Detect 'Wake' of Betelgeuse’s Elusive Companion Star

    January 05, 2026Release ID: 2026-002 Missions: Hubble

    After nearly a decade of tracking the giant star’s hidden companion, scientists have confirmed its existence and the influence it exerts.

    An illustration of the red supergiant star Betelgeuse, its companion star, and a dusty wake. The disk of a red-orange star is in the center. It is surrounded by a diffuse orange cloud representing its extended atmosphere. Below it about one stellar diameter away is a yellow dot representing a smaller companion star. From the companion, a dark red cloud wraps around in a counterclockwise direction. It begins very narrow and expands as it gets further from the companion, finally disappearing at the outer edge of the diffuse orange cloud around 10 o’clock. The words “artist’s concept” are at lower right.

    A region of space mostly filled with background galaxies, with one prominent star at upper left. A large blob of purple haze occupies much of the field. Within the purple region, an unremarkable area is outlined with a dashed white circle.

  11. NASA's Hubble Reveals Largest Found Chaotic Birthplace of Planets

    December 23, 2025Release ID: 2025-025 Missions: Hubble

    Vast dust and gas disk offers insight into the birth of star systems.

    Near the center is an object that resembles an edge-on view of a hamburger. There is a diagonal dark strip (the meat patty) of dust, running from 1 o'clock to 7 o'clock, that obscures a central star. Curving away from either side of the dark strip are glowing white clouds (the buns) where dust is reflecting starlight. Bright blue finger-like wisps of material extend far above and below the dark center plane. A few dozen stars, some with four diffraction spikes, are scattered on the black background of space.

    The spectacular, resulting dust cloud mimics the appearance of a planet.

    Image labeled Fomalhaut system, Hubble Space Telescope. A grainy orange oval ring tilts slightly from upper right to lower left. At two o'clock, a white box outlines the ring's edge and white lines extend to a larger pullout at lower right. Two spots are labeled cs1 2013 and cs2 2023. Inside the ring is a black circle with a white star symbol in the middle.

  13. NASA’s Hubble Sees White Dwarf Eating Piece of Pluto-Like Object

    September 18, 2025Release ID: 2025-024 Missions: Hubble

    Only Hubble with its unique ultraviolet vision could see this event

    An illustration showing a glowing white object in the upper left corner. This object is encircled by hundreds of thin, concentric, pale-yellow rings on an angle from bottom left to top right. The rings are palest closest to the central, glowing white object. A curving trail of gray, rock-like fragments marches across the right side, through the thin rings and joins the rings at far right. The eight largest fragments of varying sizes appear in the foreground. These objects have white, comet-like tails streaking away from the glowing white object in the rings’ center. The curving trail of fragments bends toward the glowing white object. At the bottom left corner is the label Artist’s Concept.

  14. NASA's Hubble Uncovers Rare White Dwarf Merger Remnant

    August 13, 2025Release ID: 2025-020 Missions: Hubble

    Forensic evidence comes from dwarf’s unusual spectrum

    An illustration of a white dwarf star merging with a red giant star. The red giant is an arch across the bottom of the illustration, with a textured surface. The white dwarf is a white pinpoint object at upper center right. The white dwarf in embedded inside a teardrop-shaped cocoon of white gas. It is enveloped in a white open ellipsoid that is the bow shock from speeding through the red giant’s outer atmosphere. The words “artist’s concept” are at lower left.

  15. As NASA Missions Study Interstellar Comet, Hubble Makes Size Estimate

    August 07, 2025Release ID: 2025-022 Missions: Hubble

    Icy Comet Nucleus is No Bigger Than a Few Miles Across  

    At the center of the image is a comet that appears as a teardrop-shaped bluish cocoon of dust coming off the comet’s solid, icy nucleus and seen against a black background. The comet appears to be heading to the bottom left corner of the image. About a dozen short, light blue diagonal streaks are seen scattered across the image, which are from background stars that appeared to move during the exposure because the telescope was tracking the moving comet.
