Euclid's First Data Release: A Stepping Stone to its 3D Map of the Sky

The Brief · written from 8 sources

  • ESA and the Euclid Consortium released the first major data batch, DR1-Foundation, from the Euclid space telescope on 12 November 2026.
  • The release covers 13 months of observations and captures light from more than a billion objects over a sky area equivalent to 9,500 full moons.
  • The data lays the foundation for what is intended to be one of the largest-ever 3D maps of the universe, aimed at studying dark energy and dark matter.

Why it matters

The public data release gives astronomers a large, standardised catalogue of galaxies and lensing candidates to build cosmology analyses on, and it shows the mission is on track toward its planned 3D map.

Who’s affected

  • astronomers and cosmologists
  • researchers working on dark energy and dark matter

The ESA's Euclid Space Telescope has released its first huge batch of data. It's all part of the telescope's mission to study dark energy and dark matter. The telescope is busy creating the largest ever 3D map of the Universe with its huge 600 megapixel camera, and new images…
