Shimmering galaxies revealed in new photos by European space telescope

A nebula resembling a horse's head, never-before-seen distant galaxies and "circumstantial evidence" of elusive dark matter: the European Space Agency has released the first images from its Euclid space telescope, illustrating its wide-lens view of the universe. Euclid blasted off in July on the world's first-ever mission aiming to investigate the enduring cosmic mysteries of dark matter and dark energy.
