[漢羅] Kā NGC 3169 敨--開

捲螺仔星系 NGC 3169 看起來就敢若是一蜷宇宙膨紗當咧散--開。 伊離咱有 7000 萬光年遠，就 tī 光光 ê 軒轅十四 南方、暗暗 ê 六分儀座 遐。 倒爿 ê NGC 3169 kah 伊邊仔 ê NGC 3166 發生 重力交互作用，所以 in ê 捲螺仔手骨就去予搝出來，變做潮汐尾溜。 落尾這寡星系會合併做一个，這是 本地宇宙 內底較光 ê 星系 ê 共同運命。 Tī 這張深空 ê 彩色 星系團體相片 內底，搝長 ê 恆星流 表示講，遮當咧進行重力交互作用。 照研究小組估算 ê 距離 40 萬光年來算，這个 望遠鏡視野 差不多有 20 角分遐爾大。 這張相片正爿閣有一个較細、較藍 ê NGC 3165。 咱知影 NGC 3169 ê 光譜範圍是 ùi 電波 到 X 光。 伊 ê 核心有一个活跳星系核，內底有 一粒超大質量烏洞。

[English] Unraveling NGC 3169

Spiral galaxy NGC 3169 looks to be unraveling like a ball of cosmic yarn. It lies some 70 million light-years away, south of bright star Regulus toward the faint constellation Sextans. Wound up spiral arms are pulled out into sweeping tidal tails as NGC 3169 (left) and neighboring NGC 3166 interact gravitationally. Eventually the galaxies will merge into one, a common fate even for bright galaxies in the local universe. Drawn out stellar arcs and plumes are clear indications of the ongoing gravitational interactions across the deep and colorful galaxy group photo. The telescopic frame spans about 20 arc minutes or about 400,000 light-years at the group's estimated distance, and includes smaller, bluish NGC 3165 to the right. NGC 3169 is also known to shine across the spectrum from radio to X-rays, harboring an active galactic nucleus that is the site of a supermassive black hole.
