"Euclid Launches Dark Universe Survey"
The European Space Agency's Euclid space telescope has commenced its survey of the dark Universe, aiming to observe billions of galaxies over 10 billion years of cosmic history. Despite encountering challenges with unwanted sunlight affecting its visibility, the team quickly re-designed the survey strategy to ensure its success. Euclid's wide and deep surveys over the next six years will provide valuable insights into the shapes of billions of galaxies and the distribution of dark matter in the Universe, with the first year of cosmology data expected to be released in summer 2026.
