  1. NASA's Hubble Sees Asteroids Colliding at Nearby Star for First Time

    December 18, 2025Release ID: 2025-008 Missions: Hubble

    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.

  2. NASA’s Webb Observes Exoplanet Whose Composition Defies Explanation

    December 16, 2025Release ID: 2025-134 Missions: Webb

    Bizarre, lemon-shaped world has an atmosphere unlike any ever seen before.

    Illustration labeled “artist’s concept” at right bottom corner. At left bottom corner, a partially illuminated, lemon-shaped exoplanet appears against a black background. This planet is most brightly illuminated at its elongated tip on its right side. On the left side, which is wider, the planet trails off into the darkness of the background. The planet is colored in varying, mottled shades of red, light pink, and fuchsia. Most of the pink occurs closest to the tip, while most of the fuchsia is at the top and bottom edges. At right top corner, a white beam emanates diagonally, oriented from 10 o’clock to 4 o’clock, from either side of a small, glowing, white star.

  4. NASA's Webb Telescope Studies Moon-Forming Disk Around Massive Planet

    September 29, 2025Release ID: 2025-142 Missions: Webb

    The disk offers insight into how the moons of solar system gas giants like Jupiter might have formed.

    An illustration of a young planet with a surrounding disk of dust and gas potentially forming moons. The planet, which appears dark red, is shown at lower right, circled by a cloudy, clumpy reddish orange-colored disk. The host star appears at upper left, and glows yellow, with its own reddish disk of debris. The disk that surrounds the planet takes up about half the illustration. The black background of space is speckled with stars. At the bottom of the illustration, graphics of molecules are listed in the following order: diacetylene, hydrogen cyanide, propyne, acetylene, ethane, carbon dioxide, benzene. The words Artist’s Concept appear at upper right.

  5. NASA Webb Looks at Earth-Sized, Habitable-Zone Exoplanet TRAPPIST-1 e

    September 08, 2025Release ID: 2025-109 Missions: Webb

    While an original atmosphere is unlikely, scientists are narrowing possibilities for TRAPPIST-1 e’s secondary atmosphere, even as Webb observations of the exoplanet continue.

    Illustration of a star with multiple flares and four small orbiting planets. Star is at the center of the image, with a silhouetted planet to its lower right. A smaller planet is shown an inch to the left, also silhouetted. A third planet is directly to the left of the star, gray and white but without much detail, and farther out near the left edge of the image is the fourth planet, also gray with little detail.

  6. Webb Narrows Atmospheric Possibilities for Earth-sized Exoplanet TRAPPIST-1 d

    August 13, 2025Release ID: 2025-120 Missions: Webb

    Could planets orbiting red dwarf stars like TRAPPIST-1 be habitable? Webb scientists say the investigation is ongoing.

    A planet is silhouetted in front of a star. The star shows a large eruption on one side and more wisps of red coming from its southern hemisphere. Two more planets appear in the background.

  7. NASA's Webb Finds New Evidence for Planet Around Closest Solar Twin

    August 07, 2025Release ID: 2025-135 Missions: Webb

    Data shows planet could be a gas giant, orbiting 1 to 2 times the distance between Sun and Earth.

    Three panels, each showing a different view of the binary star system Alpha Centauri. The panel at the left is a Digitized Sky Survey image showing a single bright point source at the center of a black image with small stars scattered throughout. The very center of this bright source is outlined with a vertical box, tilted slightly to the left, with two diagonal lines leading to the second panel. The Hubble Space Telescope image shows two white stars with 4 diffraction spikes each against a black background. The top star is labeled Alpha Cen B and the bottom Alpha Cen A. Alpha Cen A is outlined with a white square with two diagonal lines leading to the third panel at the furthest right, which shows a James Webb Space Telescope image of the star. Within a large white circle there is a blurry red-toned field with an orange star icon and central black circle outlined in white marking the location of Alpha Cen A. A bright orange blob at 9 o’clock in relation to the star is labeled “S1” and circled.

  8. Likely Saturn-Mass Planet Imaged by NASA Webb Is Lightest Ever Seen

    June 25, 2025Release ID: 2025-126 Missions: Webb

    The newfound planet represents Webb’s first direct image discovery of a planet.

    An image of a nearby star and its vicinity. The star itself has been blocked out and its bright light has been removed, appearing black. A dashed circle with a star symbol at the center of the image marks the star’s location. A fuzzy blue disk surrounds the star. An orange spot, near the star and inside this disk around 2 o’clock, is identified as a planet orbiting the star. A fainter orange spot at the lower left edge marks a distant star.

  9. Frigid Exoplanet in Strange Orbit Imaged by NASA's Webb

    June 10, 2025Release ID: 2025-125 Missions: Webb

    First image ever taken of exoplanet in extremely mis-aligned system

    This image shows the exoplanet 14 Herculis c. The view is mostly black, with very faint red splotches in the central region of the image. At the center of the image, there is a black circle, and in the center of that, there is a star symbol representing a real star. This black circle blocks the light from the host star. To the lower right of the circle is a fuzzy bright orange circle, which is the exoplanet.

  10. NASA's Webb Lifts Veil on Common but Mysterious Type of Exoplanet

    May 05, 2025Release ID: 2025-113 Missions: Webb

    Scientists determine atmospheric makeup of small, hot, gassy sub-Neptune.

    Illustration showing a large fuzzy blue planet in the foreground, and an orange-yellow star in the background. The side of the planet facing the star is lit, and the side facing away is dark. The boundary between the lit and dark sides is fuzzy. The atmosphere is almost homogeneous in color and texture, with extremely subtle variations and no sign of a surface. The star is slightly more orange than the Sun. The black background of space is scattered with white points of light.

    April 10, 2025Release ID: 2025-117 Missions: Webb

    Lingering brightness provides evidence for how planet met its demise.

    An illustration of a star after it has swallowed its own planet. The star look like an orange globe with flares coming out of various sides. A dark orange horizontal ring of material circles the host star. There is a very transparent cloud of blue dust spread out from the star.

  12. NASA's Webb Images Young, Giant Exoplanets, Detects Carbon Dioxide

    March 17, 2025Release ID: 2025-114 Missions: Webb

    Findings suggest giant exoplanets in HR 8799 system likely formed like Jupiter and Saturn.

    This image shows the planetary system HR 8799. The background is black. At the center there is a symbol representing a star labeled HR 8799. The star’s light is blocked. There are four exoplanets, which look like fuzzy dots, pictured surrounding the star. Furthest from the star is a fuzzy, faint blue dot, labeled b, at the 10 o’clock position. At the 1 o’clock position, second furthest from the star is a blueish-white fuzzy dot labeled c. Just below that is an orange dot labeled e. At the 4 o’clock position, still near the star, is another fuzzy white dot labeled d.

  14. NASA's Webb Images Cold Exoplanet 12 Light-Years Away

    July 24, 2024Release ID: 2024-127 Missions: Webb

    Epsilon Indi Ab is colder than any other imaged planet beyond our solar system.

    This image shows the exoplanet Epsilon Indi Ab. The image is mostly black, with blue scale-like features apparent in the central region of the image. At the center of the image, there is a black circle, and in the center, a symbol representing a star. This black circle blocks the light from the host star. To the lower left of the circle is a fuzzy bright orange circle, which is the exoplanet.
