[漢羅] 英仙座內底 ê 星塗

這片宇宙雲 內底有塗粉、氣體、kah 恆星，伊 tī 天頂佔差不多 6 度闊，就 tī 英雄星座 英仙座 ê 方向遐。 Tī 這个 壯麗天景 ê 倒爿頂懸，有一个迷人 ê 少年星團 IC 348。 伊 ê 邊仔是 飛行幽靈星雲，內底有閘光 ê 星際塗粉雲，tī 目錄內底 ê 編號是 Barnard 3 kah Barnard 4。 正爿有另外一个活跳 ê 恆星形成區 NGC 1333，伊就 tī 大型 英仙座分子雲 外圍 較烏 ê 塗粉鬚 邊仔，kah 咱 ê 距離差不多有 850 光年遠。 視野中央較暗 ê 紅光是 ùi 水素氣體 發出來–ê，週邊是厚塗粉 ê 星雲去予散射 ê 結果。 實際上，宇宙塗粉 會 kā 新形成 ê 恆星 kah 一寡初期恆星體 (YSO) 抑是 原恆星 藏起來，予光學望遠鏡揣無。 原恆星 是 ùi 分子雲內底 密度較懸 ê 雲核生出來–ê，紲落來才靠 自搝引力 ê 崩塌，形成新 ê 恆星。 咱若是照這个分子雲 ê 距離來 估算，這个視野差不多有 9 光年闊。

[English] Stardust in Perseus

This cosmic expanse of dust, gas, and stars covers some 6 degrees on the sky in the heroic constellation Perseus. At upper left in the gorgeous skyscape is the intriguing young star cluster IC 348 and neighboring Flying Ghost Nebula with clouds of obscuring interstellar dust cataloged as Barnard 3 and 4. At right, another active star forming region NGC 1333 is connected by dark and dusty tendrils on the outskirts of the giant Perseus Molecular Cloud, about 850 light-years away. Other dusty nebulae are scattered around the field of view, along with the faint reddish glow of hydrogen gas. In fact, the cosmic dust tends to hide the newly formed stars and young stellar objects or protostars from prying optical telescopes. Collapsing due to self-gravity, the protostars form from the dense cores embedded in the molecular cloud. At the molecular cloud’s estimated distance, this field of view would span over 90 light-years.
