[漢羅] 彗星形雲球

這个無四常 ê 星際結構是啥物？ 這寡 有 明亮邊緣 ê 水流形結構，就 tī 船尾座 kah 船帆座 邊仔附近 ê 豐富星場 內底。 這个星際氣體 kah 塗粉組成 ê 彗星形雲球，是 tī 1300 光年 遠 ê 所在。 是附近高溫恆星發出 ê 高能紫外光輻射，雕出這寡雲球，kā in ê 邊緣離子化，才會發光。 這寡 ùi 船帆座 超新星殘骸 來 ê 雲球，in ê 外形 嘛是 受著 超新星殘骸 ê 影響。 Tī in 內部，冷氣體 kah 塗粉 ê 核心 可能會 崩塌，形成低質量恆星。 這个過程落尾會造成 雲球散去。 事實上，倒爿頂懸 ê 彗星形雲球 CG 30 tī 頭 ê 部份發出暗暗 ê 紅光，這是 恆星形成 早期發出 ê 高能噴射流 造成 ê 現象。

[English] Cometary Globules

What are these unusual interstellar structures? Bright-rimmed, flowing shapes gather near the center of this rich starfield toward the borders of the nautical southern constellations Pupis and Vela. Composed of interstellar gas and dust, the grouping of light-year sized cometary globules is about 1300 light-years distant. Energetic ultraviolet light from nearby hot stars has molded the globules and ionized their bright rims. The globules also stream away from the Vela supernova remnant which may have influenced their swept-back shapes. Within them, cores of cold gas and dust are likely collapsing to form low mass stars, whose formation will ultimately cause the globules to disperse. In fact, cometary globule CG 30 (on the upper left) sports a small reddish glow near its head, a telltale sign of energetic jets from a star in the early stages of formation.
