[漢羅] NGC 4676：雙鼠星系相碰 ê 時陣

這兩个巨型 ê 星系互相 kā 對方搝開。 Kā 叫做「雙鼠星系」是因為 in 攏有長長 ê 尾溜。 是講兩个 捲螺仔星系 敢若已經互相迵過矣。 會產生兩條 長長 ê 尾溜，是因為兩个攏 tī 星系 較近 kah 較遠 ê 部份 產生 ê 引力差。 因為這个距離傷遠，宇宙交互作用 to̍h 敢若是慢動作，超過幾若億萬年。 NGC 4676 tī Bernice ê 頭鬃 ê 星座 (后鬃座) ê 方向揣會著，離咱有 3 億 光年 遠，可能是 彗鬚星系團 ê 成員之一。 這張相片 是 tī 2002 年用 哈伯太空望遠鏡 先進巡天 kha-mé-lah 翕 ê。 這兩隻 星系鳥鼠 可能會 tī 紲落來 ê 十億年內底，一擺閣一擺相挵，按呢 to̍h 袂繼續互相搝開。 落尾，兩个星系會 黏 做一个。

[English] NGC 4676: When Mice Collide

These two mighty galaxies are pulling each other apart. Known as the "Mice" because they have such long tails, each spiral galaxy has likely already passed through the other. The long tails are created by the relative difference between gravitational pulls on the near and far parts of each galaxy. Because the distances are so large, the cosmic interaction takes place in slow motion -- over hundreds of millions of years. NGC 4676 lies about 300 million light-years away toward the constellation of Bernice's Hair (Coma Berenices) and are likely members of the Coma Cluster of Galaxies. The featured picture was taken with the Hubble Space Telescope's Advanced Camera for Surveys in 2002. These galactic mice will probably collide again and again over the next billion years so that, instead of continuing to pull each other apart, they coalesce to form a single galaxy.
