  3. NASA's Roman Could Bring New Waves of Information on Galaxy’s Stars

    November 20, 2025Release ID: 2025-204 Missions: Roman

    It’s clear as a bell: Roman can enlighten us on the stars located in the Milky Way’s galactic bulge.

    Mosaic titled “Red Giant Echoes with Roman,” which shows 11 artist’s concepts of stars, including the Sun and 10 red giants of various radii against a black background. The illustrations are organized roughly into three rows with the grid size of the largest red giant star, located in the bottom right, the equivalent of two rows. Each star is depicted as a bright and blotchy orb. Starting with the mosaic’s smallest star, the Sun, in the top left corner and shifting to the right before moving to the next row, the illustrations become gradually larger and change from shades of light orange to red-orange. Each star’s radius is placed at the bottom of its grid. From left to right, the four light orange stars in the top row are listed with the following radii: Sun, Radius 1.0; Radius 6.3; Radius 7.0, and Radius 7.8. The second row has three orange stars and reads: Radius 8.8; Radius 9.7; and Radius 10.7. The third has four red-orange stars and reads: Radius 11.8; Radius 15.0; Radius 20.1; and Radius 33.7.

  4. Webb First to Show 4 Dust Shells 'Spiraling' Apep, Limits Long Orbit

    November 19, 2025Release ID: 2025-132 Missions: Webb

    Researchers used Webb to refine the orbit of two Wolf-Rayet stars, named for the Egyptian god of chaos, to a lengthy 190 years and confirmed a third star carves their ongoing carbon dust ejections.

    Four dust shells in Wolf-Rayet Apep expand away from three central stars that appear as a single pinpoint of light. The shells are curved, and the interior shell looks like a backward lowercase e shape.

  5. Researchers Submit Record Number of Ambitious Proposals for Webb's Fifth Year of Science

    Distant galaxies, stars and stellar populations are among most popular science categories.

    Illustration of the James Webb Space Telescope at the right with its gold, hexagon-shaped primary mirror and multi-layer sunshield. At left is a representation of its 18 primary mirror segments, which takes up about two-thirds of the view. Each segment is outlined in yellow and contains a different Webb image, artist’s concept, or spectrum (graph). The images display dying stars puffing off layers of gas and dust, spiral galaxies, planets, and deep fields of space spattered with fuzzy white galaxies. Three yellow, orange, and red wavy lines appear atop everything else, running left to right. The backdrop shows filaments of red gas and dust, white and blue stars, and distant galaxies, all against the black background of space.

    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.

  10. NASA’s Hubble Sees White Dwarf Eating Piece of Pluto-Like Object

    September 18, 2025Release ID: 2025-024 Missions: Hubble

    Only Hubble with its unique ultraviolet vision could see this event

    An illustration showing a glowing white object in the upper left corner. This object is encircled by hundreds of thin, concentric, pale-yellow rings on an angle from bottom left to top right. The rings are palest closest to the central, glowing white object. A curving trail of gray, rock-like fragments marches across the right side, through the thin rings and joins the rings at far right. The eight largest fragments of varying sizes appear in the foreground. These objects have white, comet-like tails streaking away from the glowing white object in the rings’ center. The curving trail of fragments bends toward the glowing white object. At the bottom left corner is the label Artist’s Concept.

  11. NASA’s Webb Observes Immense Stellar Jet on Outskirts of Our Milky Way

    September 10, 2025Release ID: 2025-131 Missions: Webb

    Young Star Behaves Like a Giant Roman Candle

    Gaseous yellow-orange filaments look like a rose seen from the side and tilted slightly from upper left to lower right, slightly higher than the center of the frame. Extending from the rose to upper left and lower right are gaseous outflows that appear as red lobes that have an overall shape of tall, narrow triangles with rounded tips. Each red triangle is made up of wavy, irregular lines. Dozens of stars are scattered across the field. One particularly bright white star with eight diffraction spikes is located at the top of the yellow rose. Another bright blue star with even more prominent diffraction spikes is to its lower left. The background of space is black.

  13. Glittering Glimpse of Star Birth From NASA's Webb Telescope

    September 04, 2025Release ID: 2025-136 Missions: Webb

    Nearby stellar nursery sheds light on massive star formation

    In what appears as a celestial dreamscape, a blue and black sky filled with brilliant stars covers about two thirds of the image. The stars are different sizes and shades of white, beige, yellow, and light orange. Across the bottom third of the scene is a craggy, mountain-like vista with spire-like peaks and deep, seemingly misty valleys. These so-called mountains appear in varying shades of orange, yellow, and brown. Above their soaring spires is a wispy, ethereal white cloud that stretched horizontally across the scene. Steam appears to rise from the mountaintops and join with this cloud. At the top right corner of the image, a swath of orange and brown structure cuts diagonally across the sky.
