Explanation: Taken near local midnight, this autumn night's panorama follows
the arch of the Milky Way across the northern horizon from the High Fens,
Eifel Nature Park at the border of Belgium and Germany. Shift your gaze across
the wetlands from west to east [5]  (left to right) and you can watch stars
once more prominent in northern summer give way to those that will soon
dominate northern winter nights. Setting, wanderer Mars is brightest at the
far left, still shining against almost overwhelming [6] city lights along the
southwestern horizon. Bright stars Altair, Deneb, and Vega form the northern
sky's summer triangle [7] , straddling the Milky Way left of center. Part of
the winter hexagon [8]  Capella and Aldebaran, along with the beautiful
Pleiades star cluster shine across the northeastern sky. The line-of-sight
along the hikers boardwalk leads almost directly toward the Big Dipper, an all
season asterism [9]  from these northern latitudes. Follow the Big Dipper's
pointer stars to Polaris and the north celestial pole nearly centered above
it. Andromeda, the other large galaxy [10] in the skyscape, is near the top of
the frame.
