  1. 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.

  2. 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

    Artist’s concept of spiral galaxy at the center of a much larger spherical halo of stars, with ground-based photograph pulled out to show details of the central core and spiral arms.

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

  5. 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.

  6. 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.

  7. STScI Appoints New Mission Head for the Nancy Grace Roman Space Telescope

    September 20, 2023Release ID: 2023-202

    Dr. Kristen McQuinn will assume her new role in January 2024.

  9. How NASA’s Roman Telescope Will Scan for Showstopping Explosions

    November 03, 2022Release ID: 2022-049

    Roman is set to help researchers detect more kilonovae, helping us learn significantly more about these “all-star” smashups.

    Two bright blue circular shapes that appear to be joined are left of center. They are illustrations of neutron stars merging. Debris, which is also white and bright blue, emanates in misshapen patterns primarily from where they are joining at the center.
