[漢羅] 麒麟鹿座內底 ê NGC 2403

壯麗 ê 島宇宙 NGC 2403 就 chhāi tī 長頷頸 ê 麒麟鹿座 內底。 這个捲螺仔星系 kah 咱 ê 距離差不多是 1000 萬光年，大細 5 萬光年大。 照伊 ê 大細來看，伊 ê 大質量恆星形成 HII 區 敢若是傷大。 這區 ê 紅光，是 ùi 水素原子氣體發出來--ê。 大型 ê HII 區是由一陣高溫大質量恆星提供能量。 這寡恆星上落尾會變做 足光 ê 超新星爆炸，結束 in 短短 ê 一生。 NGC 2403 是 M81 星系群 ê 成員之一。 伊 kah 咱本地星系群其中一个成員，三角座星系 M33，足成--ê。 M33 是一个有足豐富恆星形成區 ê 星系。 這張 NGC 2403 肖像 內底，有 尖尖 形體、較光 ê 恆星是咱銀河系內底 ê 前景星。 Tī 這幅深空闊幅 ê 望遠鏡視野相片內底，閣有銀河系內底 暗暗、厚塗粉 ê 星際雲，這嘛叫做 銀河卷雲 抑是 積分通量星雲 IFN。 毋過 NGC 2403 本身 湠出來 ê 較暗 ê 部份，可能是伊 kah 厝邊星系之間 ê 重力交互作用 產生 ê 潮汐恆星流。

[English] NGC 2403 in Camelopardalis

Magnificent island universe NGC 2403 stands within the boundaries of the long-necked constellation Camelopardalis. Some 10 million light-years distant and about 50,000 light-years across, the spiral galaxy also seems to have more than its fair share of giant star forming HII regions, marked by the telltale reddish glow of atomic hydrogen gas. The giant HII regions are energized by clusters of hot, massive stars that explode as bright supernovae at the end of their short and furious lives. A member of the M81 group of galaxies, NGC 2403 closely resembles a galaxy in our own local galaxy group with an abundance of star forming regions, M33, the Triangulum Galaxy. Spiky in appearance, bright stars in this portrait of NGC 2403 are in the foreground, within our own Milky Way. Also in the foreground of the deep, wide-field, telescopic image are the Milky Way's dim and dusty interstellar clouds also known as galactic cirrus or integrated flux nebulae. But faint features that seem to extend from NGC 2403 itself are likely tidal stellar streams drawn out by gravitational interactions with neighboring galaxies.
