The ESA’s Euclid space telescope has been in space for just over a year, investigating some of the deepest mysteries of the cosmos. By observing cosmic structures up to a distance of 10 billion light-years, the observatory will chart the evolution of the universe, attempt to constrain the influence of dark energy, and study the morphology of galaxies. In terms of galaxies, Euclid will attempt to answer the question of why the universe contains such a variety of galaxies, characterized by size, shape, and colors.
