This image shows an area of the mosaic released by ESA’s Euclid space telescope on 15 October 2024. The area is zoomed in 150 times compared to the large mosaic. 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.

Technical details: This colour image was obtained by combining VIS data and NISP photometry in Y and H bands. VIS and NISP enable observing astronomical sources in four different wavelength ranges. Aesthetics choices led to the selection of three out of these four bands to be cast onto the traditional Red-Green-Blue colour channels used to represent images on our digital screens (RGB). The blue, green, red channels capture the Universe seen by Euclid around the wavelength 0.7, 1.1, and 1.7 micron respectively. In the image, the stars have six prominent spikes due to how light interacts with the optical system of the telescope in the process of diffraction.
