[漢羅] Kā NGC 3169 敨--開

捲螺仔星系 NGC 3169 看起來就敢若是一粒敨--開 ê 宇宙膨紗球。 伊就 tī 7000 萬光年遠 ê 一个暗淡星座，六分儀座 內底，是 tī 較光彼粒軒轅十四 ê 南方。 因為 倒爿 ê NGC 3169 kah 隔壁 ê NGC 3166 產生 重力交互作用 ê 關係，NGC 3169 本底虯--起來 ê 捲螺仔手骨煞去予搝--開，變做闊尾 ê 潮汐尾溜。 落尾這兩个星系會合併做一个，這是 本地宇宙 內底較光 ê 星系足四常 ê 運命。 咱會當 tī 這張深空 ê 星系群 彩色相片內底，看著去予搝--出來 ê 恆星弧 kah 雲煙。 這是當咧進行重力交互作用 足明顯 ê 證據。 這張望遠鏡影像有 20 角分闊，若是照這陣天體 ê 距離來估算，按呢差不多是 30 萬光年闊。 相片正爿閣有一个 較細、反藍 ê 星系 NGC 3165。 NGC 3169 ùi 電波波段 到 X 光 波段 攏足光--ê。 伊 ê 中心 有 一粒活跳星系核，是超大質量烏洞 in 兜。

[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 at 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.
