[漢羅] 南冕座 ê 恆星 kah 塗粉

這幅望遠鏡影像內底，宇宙塗粉罩 tī 有足濟恆星彼搭，to̍h tī 南冕座，澳洲王冠 ê 北方邊界附近。 比 500 光年較近 ê 塗粉雲 kā 銀河 內底較遠 ê 背景星 ê 光攏閘牢 矣。 若是 ùi 雲估計 ê 距離來算，這幅圖面頂到下跤是 2 度闊，超過 15 光年長。 正爿面頂是一陣 古錐 ê 反射星雲，編號是 NGC 6726, 6727, 6729, kah IC 4812。 有一个特別 ê 藍光是 ùi 足燒 ê 恆星 反射 宇宙塗粉來 ê。 這个塗粉嘛 kā 這區 猶咧形成 ê 恆星 閘牢咧。 Tī 藍色發射星雲面頂，有一个較細 ê 天體 NGC 6729，to̍h 踅 tī 少年 變星，南冕座 R ê 邊仔。 伊 ê 正爿是紅光 ê 弧 kah 環。 這是 HH 天體，kah 高能、新誕生 ê 恆星有關。 壯觀 ê 球形星團 NGC 6723 to̍h tī 這幅圖 ê 倒爿下跤。 雖罔講 NGC 6723 是 這陣天體 ê 一部份，伊內底較老 ê 恆星是離咱 30000 光年遠，比 南冕座塗粉雲 內底 ê 少年恆星閣較遠。

[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. Less than 500 light-years away the dust clouds effectively block light from more distant background stars in the Milky Way. Top to bottom the frame spans about 2 degrees or over 15 light-years at the clouds' estimated distance. At top right is a group of lovely reflection nebulae cataloged as NGC 6726, 6727, 6729, and IC 4812. A characteristic blue color is produced as light from hot stars is reflected by the cosmic dust. The dust also obscures from view stars in the region still in the process of formation. Just above the bluish reflection nebulae a smaller NGC 6729 surrounds young variable star R Coronae Australis. To its right are telltale reddish arcs and loops identified as Herbig Haro objects associated with energetic newborn stars. Magnificent globular star cluster NGC 6723 is at bottom left in the frame. Though NGC 6723 appears to be part of the group, its ancient stars actually lie nearly 30,000 light-years away, far beyond the young stars of the Corona Australis dust clouds.
