Discover the first page of ESA Euclid’s great cosmic atlas and marvel at millions of stars and galaxies captured in pristine detail, in a huge 208-gigapixel mosaic. The mosaic covers an area of the Southern Sky more than 500 times the area of the full Moon as seen from Earth.
This video takes you through a rare sky dive. Starting from a vast cosmic panorama bedazzled by some 14 million galaxies, a series of ever-deeper zooms brings you to a crisp view of a swirling spiral galaxy, in a final image enlarged 600 times compared to the full mosaic.
Although the scenes are enticing, they are not taken for their beauty, but to help us advance our understanding of the cosmos. Many of the 14 million galaxies in the initial vista will be used to study the hidden influence of dark matter and dark energy on the Universe.
Unveiled as a teaser of the wide survey, the mosaic accounts for 1% of the area that Euclid will cover over six years, and was obtained by combining 260 observations collected in just two weeks.
This first chunk of Euclid’s survey was revealed on 15 October 2024 at the International Astronautical Congress in Milan, Italy, by ESA’s Director General Josef Aschbacher and Director of Science Carole Mundell.
