  1. 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.”

  2. 20-Year Hubble Study of Uranus Yields New Atmospheric Insights

    March 31, 2025Release ID: 2025-011 Missions: Hubble

    Uranus findings can aid the study of exoplanets.

    Graphic titled “Hubble Space Telescope – Observations of Uranus,” with 16 images of Uranus, arranged in a 4 by 4 grid showing changes in appearance of Uranus as observed by Hubble between 2002 and 2022.

  3. 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.

  4. NASA's Hubble, New Horizons Team Up for a Simultaneous Look at Uranus

    October 09, 2024Release ID: 2024-033 Missions: Hubble

    Learnings provide insights into capabilities needed for direct-imaging of exoplanets

    A four-panel image. The top two panels are diagrams of Uranus – spheres with gridlines going longitudinally and latitudinally. On the top left, the view from Hubble, the southern pole of the planet faces 3 o'clock. On the top right, the view from New Horizons, the southern pole faces 10 o'clock. The bottom left panel is Hubble’s actual view of Uranus – the planet is a light blue sphere, with a white circle covering the right half of the planet (the southern pole). The bottom right panel is the actual view of Uranus from New Horizons. The planet appears as a tiny whiteish dot.

  5. NASA's Webb Rings in the Holidays with the Ringed Planet Uranus

    December 18, 2023Release ID: 2023-150 Missions: Webb

    New View Reveals a Strange and Dynamic Ice World

    The planet Uranus on a black background. The planet appears blue with a large, white patch taking up the right half. The patch is whitest at the center, then fades into blue at it expands from right to left. A thin outline of Uranus is also white. Around the planet is a system of nested rings. The outermost ring is the brightest while the innermost ring is the faintest. Unlike Saturn’s horizontal rings, the rings of Uranus are vertical and so they appear to surround the planet in an oval shape. There are 9 blueish white dots scattered around the rings.

  6. NASA’s Webb Scores Another Ringed World with New Image of Uranus

    April 06, 2023Release ID: 2023-117 Missions: Webb

    Webb's infrared image highlights the planet's dramatic rings and dynamic atmosphere.

    The planet Uranus on a black background. The planet appears light blue with a large, white patch on the right side. On the edge of that patch at the upper left is a bright white spot. Another white spot is located on the left side of the planet at the 9 o’clock position. Around the planet is a system of nested rings. The outermost ring is the brightest while the innermost ring is the faintest. Unlike Saturn’s horizontal rings, the rings of Uranus are vertical and so they appear to surround the planet.
