[漢羅] 星系：Hubble 翕 ê Wild 三重奏

遮有偌濟星系咧進行交互作用？ 這陣星系叫做 Wild 三重奏 抑是 Wild 三生仔。 這毋但是因為這是 Wild 發現 ê，嘛是因為 in 看起來有三个較光 ê 星系。 這三个做伙去予編做 Arp 248，本底叫是講 in 三个攏有 交互作用。 毋過 最近 ê 研究 發現講，干焦上光彼兩个有引力 ê 交纏，就是頂懸 kah 下底較大彼兩个星系。 這張 Hubble 太空望遠鏡 翕 ê 相片內底，中央彼个 捲螺仔星系 實際上是較遠 ê，伊下底 kah 附近 ê 其他濟濟星系 嘛是仝款攏較遠。 這寡 巨人決鬥 ê 結果，就是 tī in 之間搝出一條長長 ê 星橋，內底攏是恆星、氣體、kah 塗粉。 這條星橋有 20 萬 光年 遐爾長。 咱今仔日看著 ê Wild 三生仔是差不多 2 億年前 留落來--ê，彼陣地球 ê 主人是 恐龍。 差不多閣 10 億年，這兩个交互星系就會合併 做 一个 較大 ê 捲螺仔星系。

[English] Galaxies: Wild's Triplet from Hubble

How many galaxies are interacting here? This grouping of galaxies is called the Wild Triplet, not only for the discoverer , but for the number of bright galaxies that appear. It had been assumed that all three galaxies, collectively cataloged as Arp 248, are interacting, but more recent investigations reveal that only the brightest two galaxies are sparring gravitationally: the big galaxies at the top and bottom. The spiral galaxy in the middle of the featured image by the Hubble Space Telescope is actually far in the distance, as is the galaxy just below it and all of the other numerous galaxies in the field. A striking result of these giants jousting is a tremendous bridge of stars, gas, and dust that stretches between them -- a bridge almost 200,000 light-years long. Light we see today from Wild's Triplet left about 200 million years ago, when dinosaurs roamed the Earth. In perhaps a billion years or so, the two interacting galaxies will merge to form a single large spiral galaxy.
