[漢羅] 英仙座分子雲 ê 星粉
這个星粉雲 to̍h 浮 tī 深空內底,tī 英仙座分子雲 方向 850 光年遠 ê 所在。 Tī 這幅差不多有 2 度闊 ê 望遠鏡視野內底,看會著有足明顯反射光 ê 星雲。 這个光是 ùi 藏 tī 雲內底 ê 少年恆星發出來 ê。 Tī 中央有特徵藍色 反射星雲 NGC 1333,tī 正爿面頂是反射星雲 vdB 13 ,tī 中央面頂附近是罕得看著 ê 黃色反射星雲 vdB 12。 恆星是 ùi 分子雲內底 形成 ê。 In 大部份攏 tī 可見光波段去予掖甲四界攏是 ê 塗粉閘去。 毋閣 tī NGC 1333 內底,咱猶是看會著 HH 天體發出 ê 紅色發射線。 伊是 ùi 最近形成 ê 恆星產生 ê 噴流 kah 去予衝擊波激發 ê 發光氣體。 這个混沌 ê 環境可能 kah 咱 ê 太陽 tī 45億年前形成 ê 時陣相仝。 若是按照咱估計 ê 英仙座分子雲 ê 距離來 kā 算,這个宇宙景色差不多有 40 光年遐爾闊。

[English] Stardust in the Perseus Molecular Cloud
Clouds of stardust drift through this deep skyscape, across the Perseus molecular cloud some 850 light-years away. Dusty nebulae reflecting light from embedded young stars stand out in the nearly 2 degree wide telescopic field of view. With a characteristic bluish color reflection nebula NGC 1333 is at center, vdB 13 at top right, with rare yellowish reflection nebula vdB 12 near the top of the frame. Stars are forming in the molecular cloud, though most are obscured at visible wavelengths by the pervasive dust. Still, hints of contrasting red emission from Herbig-Haro objects, the jets and shocked glowing gas emanating from recently formed stars, are evident in NGC 1333. The chaotic environment may be similar to one in which our own Sun formed over 4.5 billion years ago. At the estimated distance of the Perseus molecular cloud, this cosmic scene would span about 40 light-years.
