Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. Last week, Japan's new Subaru Telescope made its first observations of the sky. The gray building housing Subaru is visible just left of the white Keck domes near the photo's center.

Subaru will be owned and operated by Japan but located at the top of Hawaii 's Mauna Kea, a dormant volcano famous for housing several of the world's leading telescopes .
