[漢羅] M100：一个偉大設計 ê 捲螺仔星系

Tī 實際上 ê 宇宙尺度來講，M100 真正是有夠雄偉。 咱就 kā 這个星系叫做 偉大設計 ê 捲螺仔星系。 這是一个超過 1000 億粒恆星 ê 大型星系，有清楚 ê 捲螺仔手骨，kah 咱 ê 銀河系 足成--ê。 M100，嘛叫做 NGC 4321，是 室女座星系團 內底上光 ê 成員之一。 伊離咱有 5600 萬 光年 遠，就 tī Berenice 王后頭鬃 ê 星座 (后鬃座) 遐。 這張 Hubble 太空 望遠鏡 翕--ê M100 影像，是用 闊幅 kha-mé-lah 3 號 翕--ê。 影像有強調 明亮 ê 藍色 星團 kah 複雜彎曲 ê 塗粉帶，這攏是這款星系 ê 特徵。 對 M100 內底 ê 變星 研究，是決定 宇宙大細 kah 年歲 足重要 ê 角色。

[English] M100: A Grand Design Spiral Galaxy

Majestic on a truly cosmic scale, M100 is appropriately known as a grand design spiral galaxy. It is a large galaxy of over 100 billion stars with well-defined spiral arms that is similar to our own Milky Way Galaxy. One of the brightest members of the Virgo Cluster of galaxies, M100 (alias NGC 4321) is 56 million light-years distant toward the constellation of Berenice's Hair (Coma Berenices). This Hubble Space Telescope image of M100 was taken with the Wide Field Camera 3 and accentuates bright blue star clusters and intricate winding dust lanes which are hallmarks of this class of galaxies. Studies of variable stars in M100 have played an important role in determining the size and age of the Universe.
