[漢羅] 英仙座 內底 ê 雙星團

這个 美麗 ê 星空 是 tī 北天 ê 英仙座，伊 ê 視野差不多佔 3 粒月娘（1 度半）遐爾大。 伊內底有一對有名 ê 開放星團，英仙座 h kah 英仙座 χ (chi)。 頂懸彼个去予編做 NGC 869，下底彼个去予編做 NGC 884。 兩个星團攏 tī 差不多 7000 光年遠 ê 所在，內底攏有比咱太陽較少年、較高溫 ê 恆星。 這兩个星團之間 ê 距離才幾若百光年爾爾。 根據 星團內底 逐粒恆星 ê 年歲來看，這兩个星團 ê 年歲攏仝款 1300 萬歲，表示講 in 兩个應該是仝一个恆星形成區 ê 產物。 這个雙星團一直是 雙筒千里鏡足愛看 ê 天體之一。 若是 tī 較暗 ê 所在，咱閣會使直接用目睭看著伊。

[English] The Double Cluster in Perseus

This pretty starfield spans about three full moons (1.5 degrees) across the heroic northern constellation of Perseus. It holds the famous pair of open star clusters, h and Chi Persei. Also cataloged as NGC 869 (top) and NGC 884 and NGC 884, both clusters are about 7,000 light-years away and contain stars much younger and hotter than the Sun. Separated by only a few hundred light-years, the clusters are both 13 million years young based on the ages of their individual stars, evidence that they were likely a product of the same star-forming region. Always a rewarding sight in binoculars, the Double Cluster is even visible to the unaided eye from dark locations.
