Euclid mission releases first data: 900M galaxies, 15K strong lensing candidates

ESA's Euclid mission released its first major data set, cataloging over 900 million galaxies and identifying roughly 15,000 strong gravitational lensing candidates. This is a first major release from the mission, and the lensing sample could constrain dark matter models. The data's full scientific impact is pending further analysis and peer review.
