[漢羅] 英仙座 內底 ê 雙 星團

真少星團會 chhāi 遮爾倚。 這是咱 tī 夜空 用目睭就有通直接看著 ê 天體，tī 西元前 130 年 彼陣去予 希臘天文學家 Hipparchus 編 tī 星表內底。 這組 開放星團 離咱有 7000 光年遠，嘛是用雙筒千里鏡就有通看著 ê 目標。 In 是希臘神話內底 ê 英雄星座，tī 北天 一个 引人注目 ê 星場，英仙座 內底。 這兩个星團咱這馬 kā 叫做 英仙座 h kah χ，嘛會當叫做 NGC 869（正爿頂懸彼个） kah NGC 884。 In 兩个 ê 距離干焦幾若百 光年 遠，內底有足濟比 太陽 閣較少年、閣較燒 ê 恆星。 這兩个 星團 ê 年歲，照 in ê 成員星來估算，嘛差不多老。 毋但按呢，in 兩个 ê 距離嘛有相倚。 這表示講，這兩个 星團 應該是 ùi 仝一个 恆星形成區 生出來–ê。

[English] A Double Star Cluster in Perseus

Few star clusters this close to each other. Visible to the unaided eye from dark sky areas, it was cataloged in 130 BC by Greek astronomer Hipparchus. Some 7,000 light-years away, this pair of open star clusters is also an easy binocular target, a striking starfield in the northern constellation of the mythical Greek hero Perseus. Now known as h and chi Persei, or NGC 869 (above right) and NGC 884, the clusters themselves are separated by only a few hundred light-years and contain stars much younger and hotter than the Sun. In addition to being physically close together, the clusters’ ages based on their individual stars are similar - evidence that both clusters were likely a product of the same star-forming region.
