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.
