[漢羅] Hubble 翕--ê 肚胿仔星系

是按怎這个星系 ê 尾溜遮爾長？ 這張相片是 ùi Hubble 影像資料庫 內底來--ê。 這个戲劇性 ê 美麗相片，是 捲螺仔星系 Arp 188，肚胿仔星系。 這尾 宇宙肚胿仔 是 tī 天龍座 方向，離咱 4.2 億光年遠 ê 所在。 伊有 引人注意 ê 尾溜，差不多有 28 萬 光年 長，閣有光爍爍 ê 大質量 藍色星團。 有一款 講法 是，這進前應該是有一粒 較實密 ê 外來星系 ùi Arp 188 面頭前行過，ùi 正爿行到倒爿，去予 肚胿仔星系 ê 引力 搝到後面去。 In 兩粒星系 接近 ê 時陣，引潮力 kā 捲螺仔星系 內底 ê 恆星、氣體、塗粉 攏 搝搝出來，變做這條壯麗 ê 尾溜。 外來 星系應該是 tī 肚胿仔星系 後壁 30 萬光年遠 ê 所在，就 tī 相片正爿頂懸，捲螺仔手骨 頭前。 肚胿仔星系 就 kah 伊 ê 名 仝款，年歲較大了後，伊 ê 尾溜 就會無去矣。 尾溜內底 ê 星團會變做 這个大粒捲螺仔星系 ê 細粒衛星星系。

[English] The Tadpole Galaxy from Hubble

Why does this galaxy have such a long tail? In this stunning vista, based on image data from the Hubble Legacy Archive, distant galaxies form a dramatic backdrop for disrupted spiral galaxy Arp 188, the Tadpole Galaxy. The cosmic tadpole is a mere 420 million light-years distant toward the northern constellation of the Dragon (Draco). Its eye-catching tail is about 280 thousand light-years long and features massive, bright blue star clusters. One story goes that a more compact intruder galaxy crossed in front of Arp 188 - from right to left in this view - and was slung around behind the Tadpole by their gravitational attraction. During the close encounter, tidal forces drew out the spiral galaxy's stars, gas, and dust forming the spectacular tail. The intruder galaxy itself, estimated to lie about 300 thousand light-years behind the Tadpole, can be seen through foreground spiral arms at the upper right. Following its terrestrial namesake, the Tadpole Galaxy will likely lose its tail as it grows older, the tail's star clusters forming smaller satellites of the large spiral galaxy.
