The Dark Seahorse in Cepheus Image Credit & [3]Copyright: [4]Jeff Herman Explanation: Spanning light-years, this [5]suggestive shape known as the Seahorse Nebula appears in silhouette against a rich, luminous background of stars. Seen toward the royal northern constellation of Cepheus, the dusty, obscuring clouds are 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 stars of Cepheus add to this [10]pretty, galactic skyscape.
