Euclid
Wide-field survey mission for dark energy, lensing and galaxy evolution.
Overview
ESA's Euclid mission images a third of the sky in visible and near-infrared light from L2, mapping galaxy shapes and distances. Its weak-lensing and clustering measurements aim to pin down the nature of dark energy and dark matter.
Key discoveries
- First Euclid deep fields released from 2024
- Early weak-lensing measurements over large sky areas
- Growing catalogue of resolved galaxies for cosmology
