Location of Euclid Deep Fields on Gaia and Planck sky map

This image shows examples of galaxies in different shapes, all captured by Euclid during its first observations of the Deep Field areas. As part of the data release, a detailed catalogue of more than 380 000 galaxies was published, which have been classified according to features such as spiral arms, central bars, and tidal tails that infer merging galaxies. [Image description: A collage of nine by five squares containing galaxies of many different shapes and viewed in different orientations. For example, the first column shows five edge-on galaxies, which appear thin like a pencil. The galaxies in the second column have a more fuzzy, diffuse appearance. The middle columns showcase face-on spiral galaxies with many different shapes and densities of stars. The last two columns include interacting galaxies or galaxies with an unusual spiral arm or tidal tail. ]
