A combination image shows examples of galaxies in different shapes, all captured by the Euclid space telescope during its first observations of three Deep Field areas of the sky, in this handout released by the European Space Agency on March 19, 2025. As part of a Euclid data release, a detailed catalogue of more than 380,000 galaxies was published, classified according to features such as spiral arms, central bars and tidal tails that infer merging galaxies.
