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

    May 11, 2026Release ID: 2026-201

    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.

  2. NASA's Roman Poised to Transform Hunt for Elusive Neutron Stars

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

    April 16, 2026Release ID: 2026-401

    With the release of the cloud-hosted Roman Research Nexus, STScI provides astronomers around the world an environment where they can prepare to work with the massive data stream expected from NASA's Nancy Grace Roman...

  4. NASA's Roman Telescope Will Observe Thousands of Newfound Cosmic Voids

    December 15, 2025Release ID: 2025-201

    The resulting “big data” will help illuminate the nature of dark energy.

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

    November 20, 2025Release ID: 2025-204

    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.

  6. NASA Roman Core Survey Will Trace Cosmic Expansion Over Time

    August 12, 2025Release ID: 2025-202

    Roman’s High-Latitude Time-Domain Survey will find exploding stars that act as signposts to measure the universe’s expansion and the influence of dark energy.

In the right panel, the star is still visible but much fainter. Blurred versions of the same images are at top and bottom to fill in a square.

  7. NASA's Roman to Peer Into Cosmic 'Lenses' to Better Define Dark Matter

    June 12, 2025Release ID: 2025-203

    The Nancy Grace Roman Space Telescope will identify over 160,000 gravitational lenses, which magnify background galaxies that existed earlier in the universe, in search of more information about dark matter.

  8. NASA's Roman Space Telescope to Investigate Galactic Fossils

    August 29, 2024Release ID: 2024-205

    Scientists will study nearby galaxies to uncover galactic formation history and dark matter

  9. NASA's Roman Space Telescope Could Help Researchers Detect the Universe’s First Stars

    May 09, 2024Release ID: 2024-204

    Tidal disruption events offer an opportunity to locate the elusive stars.

  10. How NASA's Roman Telescope Will Measure Ages of Stars

    April 04, 2024Release ID: 2024-203

    Roman will separate young, quickly rotating stars from older, more slowly rotating stars.

  11. NASA's Roman to Use Rare Events to Calculate Expansion Rate of Universe

    February 07, 2024Release ID: 2024-202

    Lensed supernovae offer precise, independent measurement

    A field of galaxies on the black background of space. Some are blue and white, others glow yellow. In the middle of the field is a cluster of five yellowish spiral and elliptical galaxies that form a foreground galaxy cluster. There is one spiral galaxy just below the cluster that has a yellow-whiteish core and is surrounded by diffuse blue material. This galaxy is outlined by a white box, and lines extend from the box’s corners that leads to an enlarged view at the right. Four arrows point at yellow faint points of light that circle the central glow of the galaxy.

  12. NASA's Roman to Search for Signs of Dark Matter Clumps

    January 17, 2024Release ID: 2024-201

    The Roman Space Telescope’s fine resolution and panoramic views will allow researchers to examine streams of stars pulled from globular star clusters.

    An illustration of the Andromeda galaxy takes up about one third of the view. A few irregularly shaped lines representing globular cluster streams are present. Some globular cluster streams are shown with gaps.
