[漢羅] 南冕座內底 ê 恆星 kah 塗粉

Tī 這張 南冕座 北方邊界 ê 望遠鏡遠景中，有滿滿 ê 宇宙塗粉 kah 豐富 ê 恆星。 這个恆星形成區是 分子雲複合體 ê 一部份，伊才 500 光年遠爾爾。 伊 ê 大細，是另外一个閣較有名 ê 恆星托兒所，獵戶座星雲 ê 三分之一爾爾。 照這个星雲估計 ê 距離來算，這張 2 度闊 ê 相片差不多有 15 光年大。 Kah 明亮 ê 星雲濫做伙 ê 塗粉雲 kā 彼寡 tī 銀河 內底 遙遠 ê 背景恆星 ê 光閘牢牢。 這寡藏 tī 雲內底 ê 恆星，猶繼續 tī 遐 leh 進行恆星形成。 倒爿彼个是 大型烏暗星雲 Bernes 157。 正爿是 一陣 足媠 ê 反射星雲，in ê 編號是 NGC 6726，6727，6729，kah IC 4812。 In 特殊 ê 藍光是 ùi 高溫恆星反射宇宙塗粉來--ê。 較實密 ê NGC 6729 是 tī 少年變星 南冕座 R 外圍 ê 星雲。 下底 ê 弧形雲絲 kah 雲箍仔，是 kah 能量足懸 ê 新恆星 有關 ê Herbig Haro 天體。 實際上，這區中央閣有 皇冠星團，是 kah 咱上倚 ê 其中一个上活潑 ê 恆星形成區。

[English] Stars and Dust across Corona Australis

Cosmic dust clouds cross a rich field of stars in this telescopic vista near the northern boundary of Corona Australis, the Southern Crown. Part of a sprawling molecular cloud complex this star forming region is a mere 500 light-years away. That's about one third the distance of the more famous stellar nursery known as the Orion Nebula. The 2 degree wide frame would span 15 light-years at the clouds' estimated distance. Mixed with bright nebulosities the dust clouds effectively block light from more distant background stars in the Milky Way and obscure from view embedded stars still in the process of formation. Large dark nebula Bernes 157 is on the left. To its right are a group of pretty reflection nebulae cataloged as NGC 6726, 6727, 6729, and IC 4812. Their characteristic blue color is produced as light from hot stars is reflected by the cosmic dust. The more compact NGC 6729 surrounds young variable star R Coronae Australis. Just below it, filamentary arcs and loops are identified as Herbig Haro objects associated with energetic newborn stars. In fact, at the heart of this area lies the Coronet Cluster, one of the nearest and most active star forming regions.
