[漢羅] 球形星團 半人馬座 Omega

球形星團 半人馬座 Omega ê 直徑是 150 光年，這个範圍 內底有 1000 萬粒 比太陽較老 ê 恆星。 伊 ê 編號是 NGC 5139，tī 1 萬 5000 光年遠 ê 所在，是銀暈內底 已經知影 ê 200 粒 球形星團 內底上大、上光--ê。 大部份 星團攏是 差不多年歲 ê 恆星組成--ê。 毋過神祕 ê 半人馬座 Omega 煞有無仝年歲、無仝化學豐度 ê 恆星族群。 實際上，半人馬座 Omega 可能是一个 較細粒星系 kah 銀河系合併過程中，留落來 ê 核心。 半人馬座 Omega ê 紅巨星是 黃色--ê，tī 這張 清楚 ê 望遠鏡景色 內底是真好揣。 Hubble 太空望遠鏡 tùi 這款 實密星團 已經研究 20 外冬矣。 目前 ê 證據表示講，半人馬座 Omega 中心 附近 有一个大質量烏洞。

[English] Globular Cluster Omega Centauri

Globular star cluster Omega Centauri packs about 10 million stars much older than the Sun into a volume some 150 light-years in diameter. Also known as NGC 5139, at a distance of 15,000 light-years it's the largest and brightest of 200 or so known globular clusters that roam the halo of our Milky Way galaxy. Though most star clusters consist of stars with the same age and composition, the enigmatic Omega Cen exhibits the presence of different stellar populations with a spread of ages and chemical abundances. In fact, Omega Cen may be the remnant core of a small galaxy merging with the Milky Way. With a yellowish hue, Omega Centauri's red giant stars are easy to pick out in this sharp telescopic view. A two-decade-long exploration of the dense star cluster with the Hubble Space Telescope has revealed evidence for a massive black hole near the center of Omega Centauri.
