  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. NASA's Webb Reveals New Details, Mysteries in Jupiter's Aurora

    May 12, 2025Release ID: 2025-108 Missions: Webb

    Webb sees the aurora flickering, fluctuating, and undulating at Jupiter’s north pole.

    Three panels show the top of a planet in shades of orange. A bright ribbon wraps around the planet's pole. Inside the circle formed by the ribbon is a more mottled area. Below the ribbon, the planet is much darker.

  3. 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.

  5. 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.

    October 09, 2024Release ID: 2024-011 Missions: Hubble

    Titanic Storm Wiggles Like a Plate of Gelatin

    Eight Hubble images showing Jupiter's Great Red Spot (GRS). The GRS appears as a bright red oval in the middle of cream-colored cloud bands. The images trace changes in the GRS’s size, shape, brightness, color, and twisting, over a period of 90 days between December 2023 and March 2024.

  8. Hubble Tracks Jupiter's Stormy Weather

    March 14, 2024Release ID: 2024-009 Missions: Hubble

    Cyclones, Wind Shear, Violent Storms Churn in Jupiter's Atmosphere

    A side-by-side image showing both faces of Jupiter on the black background of space. At the top, left corner of the left-hand image is the label Jupiter. Centered at the bottom is the label "January 5, 2024." Jupiter is banded in stripes of brownish orange, light gray, soft yellow, and shades of cream, punctuated with many large storms and small white clouds. The largest storm, the Great Red Spot, is the most prominent feature in the left bottom third of this view. To its lower right is a smaller reddish anticyclone, Red Spot Jr. On the right-hand image, centered at the bottom is the label "January 6, 2024." This opposite side of Jupiter is also banded in stripes of brownish orange, light gray, soft yellow, and shades of cream, with many large storms and small white clouds punctuating the planet. At upper right of center, a pair of storms appear next to each other: a deep-red, triangle-shaped cyclone and a reddish anticyclone. Toward the far-left edge of this view is Jupiter's tiny orange-colored moon Io.

  9. 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.

  10. NASA's Webb Discovers New Feature in Jupiter's Atmosphere

    October 19, 2023Release ID: 2023-147 Missions: Webb

    Narrow jet stream near equator has winds traveling 320 miles per hour.

    Jupiter dominates the black background of space. The image is a composite, and shows Jupiter in enhanced color, featuring the planet's famous Great Red Spot, which appears white with light pink around the edges. The planet is striated with swirling horizontal stripes of green, periwinkle, light pink, and cream. Horizontally across the equator is a wide cream-colored band, whose height extends about 1/7 of the planet. This is the planet’s equatorial zone. The stripes across the planet interact and mix at their edges. Along both of the northern and southern poles, the planet glows in green. Bright red auroras glow just above the planet’s surface at both poles.

  11. NASA’s Webb Finds Carbon Source on Surface of Jupiter’s Moon Europa

    September 21, 2023Release ID: 2023-113 Missions: Webb

    Carbon suggests favorable environment for life in subsurface ocean 

    A blue-and-white sphere against a black background is somewhat reminiscent of the famous “Blue Marble” picture of Earth from space. With fuzzy, diffuse edges, this sphere features darker blue patches in most of the northern hemisphere facing the viewer. One, large, crescent-shaped, white patch extends along left side of the southern hemisphere facing the viewer, and a larger, blobby, white patch covers the middle latitudes of the right side of the southern hemisphere. Lighter blue regions border these white patches in the south.

  12. Neptune's Disappearing Clouds Linked to the Solar Cycle

    August 17, 2023Release ID: 2023-019 Missions: Hubble

    As Sunspots Come and Go, So Does the Cloudy Weather on the Blue Giant Planet

    This sequence of Hubble Space Telescope images chronicles the waxing and waning of the amount of cloud cover on Neptune. This display shows Hubble snapshots of the planet taken in the years 1994, 1998, 2000, 2002 (top row, from left to right) and 2006, 2010, 2015, 2020 (bottom row, from left to right). The planet is blue (due to methane absorption of red light in its atmosphere) and the high-altitude, cirrus-like clouds are white. A comparison of Neptune's cloud cover corresponds to peaks in the 11-year-long repeating solar cycle where the Sun's level of activity rhythmically rises and falls. Apparently, an increase in solar ultraviolet radiation causes chemical changes that affect Neptune's amount of cloud cover.

  13. 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.

  14. Hubble Finds Saturn's Rings Heating Its Atmosphere

    March 30, 2023Release ID: 2023-009 Missions: Hubble

    A Rain of Icy Particles Is Affecting the Giant Planet's Weather
