The Dark Seahorse of Cepheus

Explanation: Spanning light-years, this 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 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 Milky Way stars of Cepheus add to this stunning galactic skyscape.

说明: 这个横跨数光年且形状会引发联想的黑暗轮廓,是浮现于仙王座诸多背景亮星前的海马星云。这团位于北方仙王座方向的暗星云,为距离约1,200光年远的银河系分子云中的一部分。在20世纪初的天文学家巴纳德所编录的182个暗星云目录中,海马星云被编录为巴纳德150(B150)。在远红外光段的观测中,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,位在银河系中仙王座之内色彩缤纷的恒星,仍为这片美丽的银河星野增添不少风采。
