  1. STScI Scientists Surprised to Find Brightness ‘Gap’ in Ancient Star Cluster

    June 03, 2026Release ID: 2026-405 Missions: STScI

    Tools developed at STScI for the Hubble Space Telescope were critical to this discovery.

    This astronomical image is speckled with thousands of stars against the black background of space. Most stars are visible only as white pinpoints. The great majority of stars are crowding the image’s center, which appears as an irregular round shape. Most stars in the center of this cluster are whiter, and those along periphery edges yellower. The stars across the entire image range in color from blue to white to yellowish red. A few of the stars appear a bit larger and brighter than the rest, with six diffraction spikes.

  2. NASA’s Webb Reveals Black Hole That Formed Before Its Galaxy

    May 27, 2026Release ID: 2026-110 Missions: Webb

    The first direct mass measurement from the early universe weighs in on the debate over the origins of supermassive black holes.

    Space telescope image showing hundreds of bright objects of different size, color, and shape on the black background of space. Colors range from white to deep red. Shapes include elliptical, spiral, dot-like, dash-like, and arcuate. Many of the large objects near the center of the image are fuzzy white, with bright white cores. Many smaller objects scattered throughout the image are pink to red. Three objects in the central part of the image are called out with small white boxes: A box labeled “C” at about 12 o’clock; one labeled “B” at 3 o’clock; and a box labeled “A” at 4 o’clock. Images of the three objects are enlarged in boxes running vertically along the right. From top to bottom these are labeled QSO1A, QSO1B, and QSO1C. At the center of each box is a tiny, circular red dot. QSO1A (top) is notably larger, brighter, and clearer than the other two. QSO1B, in the middle, is smallest and fuzziest, and is somewhat washed out by the light of a larger white object next to it.

  3. Hubble Survey Sets Up Roman’s Future Look Near Milky Way’s Center

    May 11, 2026Release ID: 2026-201 Missions: Roman, Hubble

    This large-scale program provides a springboard to help interpret future Roman data.

    An observation (labeled “VISTA V V V Survey, Near-infrared) of the Milky Way’s center pointing toward its supermassive black hole, which is labeled Sagittarius A* (pronounced “A star”). At 7 o’clock from center is a small region, outlined with 5 fields of view from the Nancy Grace Roman Space Telescope that are stacked together in a horizontal rectangle. This region is about a third of the image in length and a fifth of the image in width. Within that same region are diagonal lines that alternate between orange and blue. A legend at the bottom left shows two Hubble instruments. One of them, marked with an orange diamond, is labeled “W F C 3 / U V I S.” The other, marked with a blue diamond, is labeled “A C S / W F C.” The background is a field of stars, gas, and dust that appear grey, except the center third that runs from the left to the right of the frame, which is composed of brown filaments of dust and gas. The tiny region surrounding Sagittarius A star appears orange.

  7. NASA's Hubble Dazzles With Young Stars in Trifid Nebula

    April 20, 2026Release ID: 2026-013 Missions: Hubble

    Actively forming stars are threaded throughout thick dust in this star-forming region.

    A tightly cropped Hubble view of a vast star-forming region known as the Trifid Nebula. The top left is bright blue. Brown and amber colors run from top right through the center in irregular, overlapping lines to the bottom-center. At bottom right, the view is almost black. Tiny, amber-colored stars appear throughout.

  8. Roman Space Telescope Science Platform Will Open New Frontiers in Space Science

  9. NASA's Webb Redefines Dividing Line Between Planets, Stars

    April 14, 2026Release ID: 2026-116 Missions: Webb

    Composition and orbit of super-chonky 29 Cygni b point to accretion within a protoplanetary disk.

    A black square labeled “29 Cyg” at upper right. In the middle, a white star symbol is surrounded by a small blue trapezoid that widens from upper left to lower right of the star. The star is labeled with a capital A. The trapezoid indicates where the star’s light has been blocked by a coronagraph. To the star’s left beyond the blue trapezoid at 8 o’clock is a fuzzy white blob labeled with a lower-case b.

  10. 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.

  11. 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.

    Movement in the Crab Nebula is clearly detectable between Hubble images

    Colorful nebula in space with a white haze throughout that is more concentrated in the center with a rippling effect. Colorful gas filaments appear to splash outward from the nebula center, colored yellow, magenta, and blue. A black border with right angles at the corners of the images show where the telescope’s field of view stops.

  14. 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.

  15. NASA’s Webb Examines Cranium Nebula

    February 25, 2026Release ID: 2026-113 Missions: Webb

    The telescope used two instruments to capture mind-bending new views of the little-known nebula PMR 1.

    Side-by-side images of the same nebula show how differently it appears in near-infrared, on the left, versus mid-infrared light, on the right. Left image is labeled NIRCam and the right is labeled MIRI. In near-infrared, the nebula’s outer bubble has a white edge and its inner clouds are orange, with a distinct dark lane cutting vertically through the center. In mid-infrared, the outer bubble has a bluish tint and there is more material in the inner clouds, which are colored off-white. The vertical dark lane is still present but more interrupted and covered by the clouds.
