[漢羅] Rubin ê 星系

這幅哈伯太空望遠鏡影像內底，有一陣明亮、閃爍 ê 恆星 chhāi tī 北天英雄 ê 星座 英仙座 ê 前景、tī 咱銀河系 ê 內底。 影像清楚對焦 tī 遠方 ê UGC 2885，彼是一个差不多離咱 2 億 3200 萬光遠 ê 巨型捲螺仔星系。 Kah 銀河系直徑 10 萬光年來比，伊差不多有 80 萬光年闊，有 1 兆粒恆星遐爾濟。 按呢差不多是銀河系內底恆星 ê 10 倍濟。 UGC 2885 ê 研究，有一部份 是欲了解星系是按怎生到遮爾大粒。 伊嘛是「趣味 ê 宇宙旅行」ê 研究目標，是天文學家 Vera Rubin tùi 捲螺仔星系 leh 轉踅 ê 領頭研究。 伊 ê 研究是頭一个會當證明講 暗物質 是 咱宇宙 主要 ê 成份。

[English] Rubin's Galaxy

In this Hubble Space Telescope image the bright, spiky stars lie in the foreground toward the heroic northern constellation Perseus and well within our own Milky Way galaxy. In sharp focus beyond is UGC 2885, a giant spiral galaxy about 232 million light-years distant. Some 800,000 light-years across compared to the Milky Way's diameter of 100,000 light-years or so, it has around 1 trillion stars. That's about 10 times as many stars as the Milky Way. Part of an investigation to understand how galaxies can grow to such enormous sizes, UGC 2885 was also part of An Interesting Voyage and astronomer Vera Rubin's pioneering study of the rotation of spiral galaxies. Her work was the first to convincingly demonstrate the dominating presence of dark matter in our universe.
