The European Space Agency's Euclid telescope has released its first color images, showcasing galaxies, clusters of stars, and stellar nurseries. The telescope is part of a mission to probe the nature of dark energy and dark matter, and one of the images is of the Perseus galaxy cluster, containing thousands of galaxies embedded in a vast cloud of hot gas. The mission is expected to provide new insights into the nature of dark energy and dark matter, and will be launched in 2022.
