3D map reveals earliest known galaxy supercluster forming in young universe

Astronomers used redshift measurements to turn a flat-looking patch of sky into a 3D map showing a proto-supercluster with 5,000 times the Milky Way's mass.

What to know

  • A new 3D map resolves what previously looked like a flat, dense patch of sky into a chain of about 10 galaxy clumps forming a supercluster, COSMOS-Z3.1-A — the earliest such structure ever found.
  • The system, along with a smaller neighbor called COSMOS-Z3.1-C, is seen as it existed when the universe was only 2-3 billion years old, roughly a quarter of its current age.
  • The mapping combined wide-field survey data from the ODIN project (Blanco 4-meter telescope, Chile) with detailed spectroscopy from telescopes in Chile, Hawaii, and Arizona to measure galaxy distances via redshift.
  • Findings, published in The Astrophysical Journal, give researchers a way to test computer models of how galaxy clusters and superclusters assemble along cosmic filaments over time.

“When we look at galaxy clusters in the nearby universe, we are seeing the finished product,”

    Social post highlights supercluster's mass and formation era

    A Bluesky user shared the finding, noting COSMOS-Z3.1-A formed when the universe was about 2.1 billion years old and has roughly 5,000 times the mass of the Milky Way.

    “New 3D maps show COSMOS-z3.1-A, an early proto-supercluster forming when the universe was just 2.1 billion years old... Incredible to see these cosmic cities taking shape so early.”

      New 3D maps show COSMOS-z3.1-A, an early proto-supercluster forming when the universe was just 2.1 billion years old. It's estimated to be 5,000 times the mass of our Milky Way. Incredible to see these cosmic cities taking shape so early.

    Astronomers unveil 3D map of early proto-supercluster COSMOS-Z3.1-A

    Using redshift measurements from large telescopes in Chile, Hawaii, and Arizona, researchers converted a 2D-looking dense patch of sky into a 3D structure, revealing it as a supercluster of about 10 galaxy clumps rather than one large cluster; a smaller nearby system, COSMOS-Z3.1-C, showed about four clumps. The study was published in The Astrophysical Journal.

    “I think the distance and sheer scale of the structures we are studying is really extraordinary. These are structures containing hundreds to thousands of galaxies. It brings home the vastness of the cosmos.”
