Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

   [2]A long vertical image shows a band of the night sky from horizon at
   the bottom to the opposite horizon -- at the image top. A person stands
     on a snow covered landscape with the central band of the Milky Way
   running between horizons. Each horizon is lit by red, yellow, and green
     auroras. Please see the explanation for more detailed information.

   Explanation: It was one of the better skies of this long night. In
   parts of [4]Antarctica, not only is it winter, but the Sun can spend
   weeks below the horizon. At [5]China's [6]Zhongshan Station, people
   sometimes venture out into the cold to photograph a spectacular night
   sky. The featured image from one such outing was taken in mid-July of
   2015, [7]just before the end of this [8]polar night. Pointing up, the
   [9]wide angle lens captured not only the ground at the bottom, but at
   the top as well. In the foreground, a colleague is taking pictures. In
   the distance, a spherical satellite receiver and several [10]windmills
   are visible. Numerous stars dot the night sky, including [11]Sirius and
   [12]Canopus. Far in the background, [13]stretching overhead from
   horizon to horizon, is the [14]central band of our [15]Milky Way
   Galaxy. Even further in the distance, visible as extended smudges near
   the top, are the [16]Large and [17]Small Magellanic [18]Clouds,
   satellite galaxies near our huge [19]Milky Way Galaxy.
