At that latitude, and at that time of year, the Milky Way \u2014 usually seen as a band of light across the sky \u2014 circles the horizon!

He also took this picture at new Moon, so there was no light from that, either. Zodiacal light is sunlight reflected back to Earth from dust in the plane of the solar system, and he chose the time of the picture to minimize that as well.<\/p>\n<p>The glow you can see in the picture is called\u00a0<a target=\"_blank\" href=\"http:\/\/en.wikipedia.org\/wiki\/Gegenschein\">gegenschein<\/a>, and is sunlight reflected back to Earth from particles in the solar system, but this light is more concentrated in the area of the sky directly opposite the Sun\u2019s position.
