Interacting galaxies from the mosaic captured by the European Space Agencys (ESA) Euclid space telescope. On the left of the image, Euclid captured two galaxies (called ESO 364-G035 and G036) that are interacting with each other, 420 million light-years from us. On the right of the image, galaxy cluster Abell 3381 is visible, 678 million light-years away from us. The area is zoomed in 150 times compared to the large mosaic, which contains 260 observations collected in two weeks. The mosaic represents only 1 percent of the wide survey that Euclid will conduct over six years. The Euclid mission, launched on 1 July 2023, aims to explore the composition and evolution of the dark Universe as part of the Cosmic Vision Programme. The space telescope will observe billions of galaxies up to 10 billion light-years away, covering more than a third of the sky.
