[漢羅] NGC 4631：海翁星系

NGC 4631 是一个大閣媠 ê 捲螺仔星系。 伊是 側向星系，離咱有 2500 萬光年遠，是 tī 北方星座 獵犬座 遐。 這个星系看起來敢若是一个小可仔彎彎 ê 栓仔，對一寡人來講這有成一隻宇宙魚仔，另外一寡人就 kā 伊叫做海翁星系。 毋管按怎，伊 ê 大細差不多 kah 咱 ê 銀河 平大。 Tī 這張遮爾清楚 ê 相片 內底，黃色 ê 星系核、烏暗 ê 塗粉雲、明亮 ê 藍色星團、kah 紅色 ê 恆星形成區攏足明顯--ê。 海翁星系頂懸彼个較細 ê 長株圓星系 NGC 4627，是伊 ê 星系伴。 咱會當 tī 這張深空相片內底看著 較暗 ê 恆星流，這是較細 ê 星系伴 tī 古早以前 kah 海翁星系相拄幾若擺，造成伊 ê 結構去予破壞了後 ê 殘骸。 咱嘛知影講，海翁星系噴出 ê 星系暈是燒氣體造--ê，會發出 X-光。

[English] NGC 4631: The Whale Galaxy

NGC 4631 is a big beautiful spiral galaxy. Seen edge-on, it lies only 25 million light-years away in the well-trained northern constellation Canes Venatici. The galaxy's slightly distorted wedge shape suggests to some a cosmic herring and to others its popular moniker, The Whale Galaxy. Either way, it is similar in size to our own Milky Way. In this sharp color image, the galaxy's yellowish core, dark dust clouds, bright blue star clusters, and red star forming regions are easy to spot. A companion galaxy, the small elliptical NGC 4627 is just above the Whale Galaxy. Faint star streams seen in deep images are the remnants of small companion galaxies disrupted by repeated encounters with the Whale in the distant past. The Whale Galaxy is also known to have spouted a halo of hot gas glowing in X-rays.
