Zoom into Euclid’s 500 gigapixel mosaic of the Universe
The Brief
- ESA's Euclid telescope released its first major batch of data, DR1-Foundation, on 12 November 2026.
- The release includes light from more than a billion objects over an area of sky about 9500 full Moons in size.
- The video zooms into the northern mosaic, nearly 500 gigapixels, made from 740 observations taken in autumn 2024 and spring 2025 for the Euclid Wide Survey.
- The mosaic covers 367 square degrees of the northern sky and lays the groundwork for Euclid's largest 3D map of the cosmos.
Why watch · It offers a close look at a very large survey dataset that forms the basis for Euclid's planned 3D map of the cosmos.

On 12 November 2026, ESA’s Euclid space telescope released its first major batch of data: DR1-Foundation. As part of this very large data release Euclid has captured the light of more than a billion objects over an area of sky as big as 9500 full Moons, laying the foundation for its largest ever 3D map of the cosmos. In this video, we zoom into the northern mosaic, which is nearly 500 gigapixels in size. This mosaic comprises 740 observations collected in autumn 2024 and spring 2025 as part of the Euclid Wide Survey, and covers 367 deg2 of the northern sky.
