[漢羅] M33 ê 水素雲

壯麗 ê 捲螺仔星系 Messier 33 看起來是有過量 ê 水素氣體 leh 發光。 M33 是本星系群 ê 成員之一,嘛叫做 三角座星系,離咱有 300 萬 光年遠。 這張 清楚 ê 宇宙肖像,就是這个星系中心 3 萬光年 ê 範圍,是 leh 翕 M33 發紅光 ê HII 區,就是水素離子雲。 這寡 HII 區就綴 M33 鬆鬆 ê 捲螺仔手骨,踅入去星系核內底。 M33 ê 大片 HII 區 是目前咱知影 上大 ê 恆星誕生區,會生出足濟短命 ê 大質量恆星。 足光 ê 大質量恆星 發出強烈 ê 紫外光輻射,kā 邊仔 ê 水素氣體 離子化,予 in 發出特別 ê 紅光。 這張影像是 kā 闊頻資料 kah H-alpha (Hα) 濾鏡紀錄 ê 狹頻資料 疊出來 ê 結果。 H-alpha (Hα) 濾鏡是 tī 可見光波段,會當 kā 上強 ê 水素 發射線 ê 信號送過來。

[English] Hydrogen Clouds of M33

Gorgeous spiral galaxy Messier 33 seems to have more than its fair share of glowing hydrogen gas. A prominent member of the local group of galaxies, M33 is also known as the Triangulum Galaxy and lies a mere 3 million light-years away. The galaxy's central 30,000 light-years or so are shown in this sharp galaxy portrait. The portrait features M33's reddish ionized hydrogen clouds or HII regions. Sprawling along loose spiral arms that wind toward the core, M33's giant HII regions are some of the largest known stellar nurseries, sites of the formation of short-lived but very massive stars. Intense ultraviolet radiation from the luminous, massive stars ionizes the surrounding hydrogen gas and ultimately produces the characteristic red glow. In this image, broadband data were combined with narrowband data recorded through a hydrogen-alpha filter. That filter transmits the light of the strongest visible hydrogen emission line.
