[漢羅] 小精靈星雲 ê 恆星形成活動

咱來看這个編號 NGC 281 ê 宇宙雲，毋過你有可能會 kā 開放星團 IC 1590 看落勾去。 這个少年、大質量恆星 ê 星團 是 tī 這个星雲內底 生出來–ê。 伊落尾會激發這个星雲，予星雲發光。 Tī NGC 281 肖像內底 這个顯目 ê 形體，是去予 星團內底 高溫恆星 強烈、高能 ê 恆星風 kah 輻射能 kā 侵蝕，雕出 塗粉柱 kah 實密 ê Bok 雲球，才會變做你看著 ê 剪影。 這區若是活較久 leh，塗粉結構就有可能變做未來 ê 恆星形成區。 NGC 281 chhāi tī 差不多1 萬光年遠 ê 仙后座，會遮爾古錐叫做 小精靈星雲，是因為伊 ê 形體。 這張清楚 ê 組合影像是 ùi 幾若張狹頻波段 ê 資料來–ê。 影像內底 ê 紅色、青色、kah 藍色，是 ùi 星雲內底 ê 水素原子 kah 酸素原子發射線 合成 來–ê。 照科學家估計 ê NGC 281 距離來看，這幅圖有超過 80 光年 闊。

[English] Star Formation in the Pacman Nebula

Look through the cosmic cloud cataloged as NGC 281 and you might miss the stars of open cluster IC 1590. Formed within the nebula, that cluster’s young, massive stars ultimately power the pervasive nebular glow. The eye-catching shapes looming in the featured portrait of NGC 281 are sculpted dusty columns and dense Bok globules seen in silhouette, eroded by intense, energetic winds and radiation from the hot cluster stars. If they survive long enough, the dusty structures could also be sites of future star formation. Playfully called the Pacman Nebula because of its overall shape, NGC 281 is about 10,000 light-years away in the constellation Cassiopeia. This sharp composite image was made through narrow-band filters. It combines emission from the nebula’s hydrogen and oxygen atoms to synthesize red, green, and blue colors. The scene spans well over 80 light-years at the estimated distance of NGC 281.
