Euclid's First Data Release: A Treasure Trove of Deep Field Galaxies
2025-03-23
The European Space Agency's Euclid mission released its first batch of survey data, offering a preview of its deep fields. This includes millions of galaxies, showcasing their large-scale organization in the cosmic web. Combining AI and citizen science, Euclid classified over 380,000 galaxies and 500 gravitational lens candidates. This rich dataset will help unravel the mysteries of dark matter and dark energy by precisely measuring the shapes and distribution of billions of galaxies across a third of the sky. The initial data, from just a week of observation, already contains 26 million galaxies, some up to 10.5 billion light-years away.
