繭狀星雲內部是一個新發育的星團。這個美麗的星雲被命名為 IC 5146 ,寬度接近 15 光年。它翱翔在北方夏夜的天空中,距離天鵝座(天鵝座)約 4000 光年。 和其他恆星形成區一樣,它也是由年輕、熾熱的恆星激發出的紅色、發光的氫氣和塵埃反射的星光組成,位於原本看不見的分子云的邊緣。 事實上,在這個星雲中心附近發現的明亮恆星很可能只有幾十萬年的歷史,當它清除分子云中形成恆星的塵埃和氣體的空腔時,為星雲發光提供了動力。經過長達 48 小時的整合,我們獲得了這一特別深的彩色檢視,它追蹤了塵封的恆星苗圃內部和周圍的誘人特徵。
原文:Inside the Cocoon Nebula is a newly developing cluster of stars. Cataloged as IC 5146, the beautiful nebula is nearly 15 light-years wide. Soaring high in northern summer night skies, it's located some 4,000 light years away toward the constellation of the Swan (Cygnus). Like other star forming regions, it stands out in red, glowing, hydrogen gas excited by young, hot stars, and dust-reflected starlight at the edge of an otherwise invisible molecular cloud. In fact, the bright star found near the center of this nebula is likely only a few hundred thousand years old, powering the nebular glow as it clears out a cavity in the molecular cloud's star forming dust and gas. A 48-hour long integration resulted in this exceptionally deep color view tracing tantalizing features within and surrounding the dusty stellar nursery.
