横跨数光年，这个令人联想的形状被称为海马星云，在丰富明亮的恒星背景下漂浮在剪影中。这片布满尘埃的黑暗星云是1200光年远的银河系分子云的一部分，正对着北方的仙王座。它也被列为巴纳德150 (B150)，是天文学家e·e·巴纳德在20世纪初编目的182个天空暗斑之一。内部正在形成一群低质量恒星，但它们坍缩的核心只有在长红外波段才能看到。尽管如此，造父座上五颜六色的银河系恒星为这幅令人惊叹的银河天空增添了色彩。成长画廊：本周的超级月食

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. Growing Gallery: This week's supermoon eclipse
