   Explanation: Do you recognize this constellation? Setting past the
   [4]Central Bohemian Highlands in the [5]Czech Republic is [6]Orion, one
   of the most identifiable star groupings on the sky and an icon familiar
   to [7]humanity for over 30,000 years. Orion has [8]looked pretty much
   the same during this time and should continue to look the same for many
   thousands of years into the future. Prominent [9]Orion is high in the
   sky at sunset this time of year, a recurring sign of (modern) winter in
   [10]Earth's [11]northern hemisphere and summer in the south. The
   featured picture is a composite of over thirty images taken from the
   [12]same location and during the same night last month. Below and
   slightly to the left of [13]Orion's three-star belt is the [14]Orion
   Nebula, while four of the [15]bright stars surrounding the belt are,
   clockwise, [16]Sirius (far left, blue), [17]Betelgeuse (top, orange,
   [18]unusually faint), [19]Aldebaran (far right), and [20]Rigel (below).
   As future weeks progress, [21]Orion will set increasingly earlier.
