Euclid mission first data release maps 900M galaxies, 15K gravitational lenses

ESA's Euclid mission released its first major data, mapping over 900 million galaxies and identifying ~15,000 gravitational lens candidates, far exceeding previous counts. This advances the study of dark matter and dark energy, though the lens candidates require confirmation. The data marks a significant step toward the mission's goal of a 3D map covering a third of the sky.
