Explanation: If you go high enough, you may find yourself on a picturesque
perch between the water clouds of the Earth and the star clouds of the Milky
Way. Such was the case last month for one adventurous alpinist
astrophotographer. Captured here [4]  in the foreground above white clouds are
mountain peaks in the Dolomite range [5]  in northern Italy [6] . This
multi-exposure image was captured from Lagazuoi [7] , one of the Dolomites.
Hundreds of millions of years ago, the Dolomites [8]  were not mountains but
islands an ancient sea that rose through colliding tectonic plates [9] . The
Dolomites divergent history accounts [10]  for its unusually contrasting
features, which include jagged crests and ancient marine fossils [11] . High
above even the Dolomites [12] , and far in the distance, dark dust [13]  lanes
streak out from the central plane of our Milky Way Galaxy [14] . The stars and
dust are dotted with bright red [15]  clouds of glowing hydrogen [16]  gas --
such as the Lagoon Nebula [17]  just above and to the left of center.
