This panorama of the Milky Way was made over several hours from a location near Pulpit Rock in the park. This can only happen during the spring when the arc of the galaxy is lower in the sky. The Milky Way is our home galaxy and contains about 200 billion stars. On a clear dark night we can see about 2500. The green glow along the horizon under the arch is air glow, a natural phenomenon resulting from sunlight-induced chemical reactions in the upper atmosphere. Hovering just above the horizon on the left side of the image is M31, the Andromeda galaxy. This galaxy has the distinction of being the most distant object visible to the naked eye and lies about 2.3 million lightyears from Earth. Also visible in the image are the many nebulae, clusters, star clouds and dust lanes that make up the Milky Way. These objects are densest towards the center of the galaxy in the constellation Sagittarius, shown here on the right side of the image. This image is the first of its kind and vividly illustrates the beauty of Black Canyon and the skies above.
