[漢羅] 哈伯太空望遠鏡翕 ê 肚胿仔星系

是按怎這个星系有遮爾長 ê 尾溜？ 這張 予人讚嘆 ê 遠景 是 哈伯遺產資料庫 ê 影像。 一个遙遠星系成做這个壯麗 ê 背景，伊是去予搝開 ê 捲螺仔 星系 Arp 188，肚胿仔星系。 這个 宇宙肚胿仔 離咱有 4.2 億光年遠，to̍h tī 北天星座 天龍座 ê 方向看會著。 這个 予人注目 ê 尾溜有 28 萬 光年 長，內底閣有大質量、明亮 ê 藍色星團。 一款講法是講，有一个閣較密 ê 入侵星系 行過 Arp 188 頭前，to̍h ùi 這張影像 ê 正爿迵到倒爿，才去予肚胿仔星系 ê 重力 hiù-去到 後壁。 Tī 這改 ê 近距離接觸，潮汐力 kā 捲螺仔星系 ê 恆星、氣體、kah 塗粉 拖--出來，才會產生這个壯觀 ê 尾溜。 這个 入侵 星系，估計是 tī 肚胿仔星系後壁 300 光年遠 ê 所在，to̍h tī 正爿面頂彼个前景 ê 捲螺仔手骨遐。 Kah 伊 ê 地球 名仝款，肚胿仔星系 ê 年歲愈大，伊 ê 尾溜 to̍h 會沓沓仔變無--去。 落尾，尾溜內底 ê 星團 to̍h 會變做這个大捲螺仔星系 ê 細衛星星系。

[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.
