   Explanation: Spanning light-years, this [5]suggestive shape known as
   the Seahorse Nebula floats in silhouette against a rich, luminous
   background of stars. Seen toward the royal northern constellation of
   Cepheus, the dusty, dark nebula is part of a Milky Way molecular cloud
   some 1,200 light-years distant. It is also listed as Barnard 150
   (B150), one of 182 [6]dark markings of the sky cataloged in the early
   20th century by astronomer [7]E. E. Barnard. Packs of low mass stars
   are forming [8]within, but their collapsing cores are only visible at
   long [9]infrared wavelengths. Still, the colorful Milky Way stars of
   Cepheus add to this stunning [10]galactic skyscape.
