Launched on July 1, 2023, the European Euclid mission will observe billions of galaxies over one-third of the sky to create a map of the Universe. But Euclid's map will be in black and white; telescopes in Hawai'i, including the Subaru Telescope, are needed to determine the colors of the galaxies. The color data will be used to deduce the distance, thus creating a 3D map, uncovering the mysteries of dark matter and dark energy.
