Euclid's first major data release maps over 900 million galaxies to probe the dark universe.

The European Space Agency's Euclid mission published its first major dataset, mapping more than 900 million galaxies. Launched in 2023, the project aims to construct the largest three-dimensional map of the cosmos to investigate dark energy and dark matter. The initial release also highlights thousands of gravitational lensing examples.

The scopeThe survey will ultimately cover a third of the sky and span over 10 billion years of cosmic history.
The lensingResearchers identified about 15,000 potential instances of gravitational lensing to help study the dark universe.

Why it matters

Mapping the distribution of galaxies across billions of years allows scientists to better understand the invisible forces driving the expansion of the cosmos. This mission provides astronomers with unprecedented observational depth to explore cosmic history.
