仙王座的宇宙动物园
2023年8月17日 A Cosmic Zoo in Cepheus Image Credit & Copyright: Yann Sainty Explanation: Sprawling emission nebulae IC 1396 and Sh2-129 mix glowing interstellar gas and dark dust clouds in this nearly 12 degree wide field of view toward the northern constellation Cepheus the King. Energized by its central star IC 1396 (left), is hundreds of light-years across and some 3,000 light-years distant. The nebula’s intriguing dark shapes include a winding dark cloud popularly known as the Elephant’s Trunk below and right of center. Tens of light-years long, it holds the raw material for star formation and is known to hide protostars within. Located a similar distance from planet Earth, the bright knots and swept back ridges of emission of Sh2-129 on the right suggest its…
仙王座的海马星云
2023年4月20日 The Dark Seahorse in Cepheus Image Credit & Copyright: Jeff Herman 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.

Tomorrow’s picture: light-weekend 黝黑的仙王座海马星云 影像提供与版权: Valerio Avitabile 说明: 这个长数光年，形状深具暗示性的天体，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。这团位在北天仙王座方向的不透光尘埃云，为距离约1,200光年远的一团银河分子云之成员。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1。在其内，藏有处于形成阶段的成群小质量恒星，不过它们塌缩中的星核，只有在远红外线波段才可见。不论如何，视野内这些色彩缤纷的仙王座恒星，为这片美丽的银河星野增添了不少风采。 明日的图片:…
仙王座内黑暗的海马星云

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 from collapsing cores only visible at long infrared wavelengths. Still, colorful stars in Cepheus add to the pretty, galactic skyscape. 仙王座内黑暗的海马星云 影像来源与版权: Sergio Kaminsky 说明：这个跨越数光年、具有暗示性外形结构的天体被称为海马星云，在繁星点点的明亮背景衬托下呈现出黑暗的轮廓。这个满是尘埃的模糊星云位于北天仙王座方向，是距离约我们1200光年远的银河系分子云的一部分。它的编录号为巴纳德150 （B150），是天文学家巴纳德在20世纪初编录的182个暗星云之一。大量的低质量恒星正在坍缩的星核中形成，这仅在长波红外波段下才能看到。此外，仙王座内五彩缤纷的恒星为这片美丽的银河星空增添了色彩。
