   Explanation: You can't [5]walk along the Milky Way. Still, under a dark
   sky [6]you can explore it. To the eye the pale luminous trail of light
   arcing through the sky on a dark, moonless night does appear to be a
   path through the heavens. The glowing celestial band is the faint,
   collective [7]light of distant stars cut by swaths of obscuring
   interstellar dust clouds. It lies along the plane of [8]our home
   galaxy, so named because it looks like a milky way. Since Galileo's
   time, the Milky Way has been revealed to telescopic skygazers to be
   filled with [9]congeries of innumerable stars and [10]cosmic wonders.
