Explanation: Spanning light-years, this 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 dark markings of the sky cataloged in the early 20th century by astronomer E. E. Barnard. Packs of low mass stars are forming within, but their collapsing cores are only visible at long infrared wavelengths. Still, the colorful stars of Cepheus add to this pretty, galactic skyscape.

说明: 这个长数光年、形状具有暗示性的天体,是以黝黑剪影之姿出现在仙王座明亮背景繁星前方的海马星云。这团位于北天仙王座方向的不透光尘埃云,为距离约1,200光年远的银河分子云之一部分。在天文学家巴纳德于20世纪初编录的暗星云表里,编录号为巴纳德150(B150)的这团星云,是其中的182个暗星云之一。在远红外光段,才得以见到此星云内的塌缩星核,正在诞生成群的小质量恒星。尽管如此,位在仙王座之内的色彩缤纷恒星,仍为这片美丽的银河星野增添不少风采。
