[漢羅] 星團 M35 kah NGC 2158

星團有近--ê 有遠--ê，有少年--ê 有 老--ê，有散--ê 有集中--ê。 這張影像 展示 tī 仝一个星場內底 ê 兩个 開放星團 相對照。 Tī 倒爿下跤 ê 是 M35，伊離咱算近 ê，差不多有 2800 光年 遠。 伊是有較少年，差不多是 1.5 億歲，嘛較散，差不多是 2500 粒恆星 tī 這个 30 光年闊 ê 空間內底。 較光 ê 藍光星，定定會當提來分辨少年 ê 開放星團， to̍h 親像 M35。 相對來講，tī 正爿頂懸 ê NGC 2158，是比 M35 閣較遠 4 倍，閣較老 10 倍，嘛較集中。 NGC 2158 內底較光 ê 藍光星已經 家己爆炸 矣，所以星團 ê 光這馬主要是一寡較老 ê kah 較黃 ê 恆星來 ê。 一般來講，開放星團會 tī 咱 ê 銀河系 ê 星系盤面頂揣著，而且不管 tī 佗位內底攏會有 100 到 10000 粒恆星。 In 攏差不多 tī 仝一个時間形成 ê。 開放星團 M35 kah NGC 2158 攏會使用細台望遠鏡 tùi 雙生仔星座（雙生仔座）ê 方向 揣著。

[English] Star Clusters M35 and NGC 2158

Clusters of stars can be near or far, young or old, diffuse or compact. The featured image shows two quite contrasting open star clusters in the same field. M35, on the lower left, is relatively nearby at 2800 light years distant, relatively young at 150 million years old, and relatively diffuse, with about 2500 stars spread out over a volume 30 light years across. Bright blue stars frequently distinguish younger open clusters like M35. Contrastingly, NGC 2158, on the upper right, is four times more distant than M35, over 10 times older, and much more compact. NGC 2158's bright blue stars have self-destructed, leaving cluster light to be dominated by older and yellower stars. In general, open star clusters are found in the plane of our Milky Way Galaxy, and contain anywhere from 100 to 10,000 stars -- all of which formed at nearly the same time. Both open clusters M35 and NGC 2158 can be found together with a small telescope toward the constellation of the Twins (Gemini).
