  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. The rings appear bright white, glowing slightly less than Webb’s infrared image. White dots, representing several of Saturn’s moons, are labeled Janus, Mimas, and Epimetheus.

  3. 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.

  4. 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.

  5. Moons of Uranus Surprise Scientists in NASA Hubble Study

    June 10, 2025Release ID: 2025-018 Missions: STScI

    New surface data from largest Uranian moons are contrary to expectations.  

    Four small, white dots appear widely spaced in a steep, roughly jagged, diagonal line from top right to bottom left. These white dots appear against a solid black background. A fifth small, white dot is superimposed on a much larger blue sphere, which is also on the black background. This medium-blue sphere has pink, white, and lighter blue diagonal striations. Also superimposed on this striated sphere is a tiny black dot, which is just to the right and slightly beneath the white dot. Encircling the blue sphere at the same steep diagonal angle as the white dots and striations are thin, ghostly, white, Saturn-like rings. The four white dots are labeled, from top right to bottom left, “Titania,” “Oberon,” “Umbriel,” and “Miranda.” The white dot and its accompanying black dot, which are both superimposed on the blue sphere, are labeled “Ariel and shadow.” The faint, Saturn-like rings encircling the blue sphere are labeled simply “rings.”

  11. NASA's Hubble Celebrates Decade of Tracking Outer Planets

    December 09, 2024Release ID: 2024-010 Missions: Hubble, STScI

    Hubble Space Telescope Keeps a Vigilant Eye on Weather on Other Worlds

    A montage of Hubble views of our solar system's four giant outer planets: Jupiter, Saturn, Uranus, and Neptune taken from 2014 to 2024 by the OPAL (Outer Planet Atmospheres Legacy) program. Upper-left toward center: The hazy white polar cap on the three teal-colored Uranus images appears more face-on as the planet approaches northern summer. Center-right to far-center right: Three images of the blue planet Neptune show the coming and going of clouds as the Sun's radiation level changes. Seven views of yellow-brown Saturn stretch across the mosaic center in a triangle, show the tilt of the ring plane relative to the view from Earth, from left to right from an oblique angle to nearly edge-on, with colorful changes to bands of clouds in the turbulent atmosphere. Bottom center: Three Jupiter images spanning nearly a decade form a triangle. Notable changes are seen in Jupiter's colorful white and brown striped cloud structure. The Great Red Spot, seen at southern latitudes, is prominent in each photo.

  14. NASA's Webb Reveals Unusual Jets of Volatile Gas from Icy Centaur 29P

    October 02, 2024Release ID: 2024-130 Missions: Webb

    Scientists revealed unexpected outgassing from this object galloping across the outer solar system.

    Artist’s concept of Centaur 29P/Schwassmann-Wachmann 1 as seen from the side against a dark, mostly starless swath of space. The rocky, bilobed nucleus is toward the right and resembles the simplified shape of a peanut. The left side of the centaur is partially illuminated by the Sun, which is off-screen, revealing the nucleus’ light brown surface. Four jets of gas, depicted as translucent cones of white, emanate from various points on the Centaur’s surface and extend beyond the frame. A label in the bottom left corner reads “Artist’s Concept.”

  15. NASA's Hubble, MAVEN Help Solve the Mystery of Mars' Escaping Water

    September 05, 2024Release ID: 2024-028 Missions: Hubble

    Results upend the classical picture that scientists previously held

    Split image of two panels stacked vertically. In the left corner of the top image is the label Mars Corona, Hubble Space Telescope. This label pertains to both panels. In the top panel, on a black background, an orange and white orb is surrounded by a small, diffuse, grainy, orange halo. The halo appears to have more material on its left side than its right. Under the orb is the label Aphelion: December 31, 2017. In the bottom panel, on a black background, a larger orange and white orb is also surrounded by a diffuse, grainy, orange halo. This halo is wider than the one in the top panel. The halo appears to have more material on its right side than its left. Under the orb is the label Perihelion: December 19, 2016. In both panels, white, polar ice caps and some surface features are visible.
