英文原文:Explanation: Spanning light-years, this suggestive shape known as the Seahorse Nebula floats in silhouette against a rich background of of stars and glowing hydrogen gas. 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 luminous depths of the Milky Way in Cepheus add to this stunning galactic skyscape . 说明: 这片被称为海马星云[3]的奇特星云,跨越数光年,在繁星点点和闪耀的氢气映衬下,呈现出迷人的轮廓。 这片尘埃弥漫的暗星云位于北天的皇家星座-仙王座方向,是距离我们约1,200光年的银河系分子云的一部分。 它也被列为巴纳德150号(B150),是天文学家E. E. 巴纳德[4]在20世纪初期编录的182个天空暗标记[5]之一。 低质量恒星群正在内部[6]形成,但它们的塌缩内核仅在长红外波段[7]下才能被观测到。 尽管如此,仙王座中银河系深邃明亮的景象,依然为壮丽的银河景观[8]增添了魅力。
