Euclid is ESA’s space telescope designed to map the geometry of the dark Universe. Over six years, Euclid is imaging billions of galaxies across more than a third of the sky, measuring gravitational lensing distortions and baryon acoustic oscillations to understand the acceleration of cosmic expansion driven by dark energy.
