仙王座的黑暗海馬
The Dark Seahorse of Cepheus

海馬星雲跨越光年,在豐富、明亮的恆星背景下,以剪影的形式漂浮著。海馬星雲位於皇家北方的仙王座,是銀河系分子云的一部分,距離銀河系約 1200 光年。它也被列為巴納德 150 (B 150 ),是天文學家 E. E. 巴納德在 20 世紀初編入星表的 182 個天空暗標之一。裡面正在形成成群的低質量恆星,但它們坍縮的核心只有在長紅外線波長下才能看到。不過,仙王座五彩斑斕的銀河恆星還是為這一迷人的銀河天景增色不少。 成長相簿:本週超級月食
原文: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
