[漢羅] 氣體 kah 塗粉 內底 ê 肚胿仔星雲
是啥物代誌予肚胿仔星雲遮爾鬧熱? 是恆星形成活動啦! 有厚塗粉發射線 ê 肚胿仔 星雲 IC 410 離咱有 1 萬 2000 光年 遠,就 tī 北天 ê 車夫 星座,御夫座 遐。 這个發光雲有超過 100 光年闊。 伊是去予藏 tī 星雲內底 ê 開放星團 NGC 1893 ê 恆星風 kah 輻射 雕出來 ê 形體。 伊是 400 萬年前 才拄 tī 星際雲內底形成--ê。 規个恆星形成雲內底攏是足光、拄生出來 ê 恆星。 注意看 這張圖 ê 倒爿下跤,有兩个較實密 ê 物質流,當咧離開星雲中心。 這寡 宇宙肚胿仔 是 IC 410 內底有機會形成新恆星 ê 所在,in 差不多有 10 光年長。 這張影像是 kā 硫磺 (紅色)、水素 (青色)、kah 酸素 (藍色) 氣體 ê 發射線加強 ê 結果,毋過已經 kā 恆星用數位處理 ê 方式 kā 提掉矣。

[English] The Tadpole Nebula in Gas and Dust
What's causing the commotion in the Tadpole Nebula? Star formation. Dusty emission in the Tadpole Nebula, IC 410, lies about 12,000 light-years away in the northern constellation of the Charioteer (Auriga). The cloud of glowing gas is over 100 light-years across, sculpted by stellar winds and radiation from embedded open star cluster NGC 1893. Formed in the interstellar cloud a mere 4 million years ago, bright newly formed cluster stars are seen all around the star-forming nebula. Notable on the lower-right of the featured image are two relatively dense streamers of material trailing away from the nebula's central regions. Potentially sites of ongoing star formation in IC 410, these cosmic tadpole shapes are about 10 light-years long. The image was processed highlighting the emission from sulfur (red), hydrogen (green), and oxygen (blue) gas -- but with the stars digitally removed.
