Arching across the night sky as shown above on this impressive panorama is the Milky Way as observed from Skyros Island , Greece. If it's sufficiently dark the Milky Way can be seen throughout the year, however, it's an easier target to observe when the Sun is on the opposite side of the sky -- during the summer months in the Northern Hemisphere . The Milky Way is most luminous (greatest density of stars) in the direction of the Galactic Center , at far right (south). Note the Church of St. Ermolaos in the background, at center. Panorama taken on July 21, 2015.
