[漢羅] 四邊形星群：獵戶座星雲 ê 心臟

這張清楚 ê 宇宙影像中心是 獵戶座星雲 ê 心臟，內底有 4 粒高溫大質量恆星，in 就是 四邊形星群。 In 相倚 tī 半徑 1.5 光年 ê 範圍內，是獵戶座星雲核心 ê 實密星團 ê 主要成員。 四邊形星 群發出 ê 電離輻射 紫外光，大部份是 ùi 一粒足光 ê 恆星，獵戶座 Theta-1 C 發出來--ê。 伊驅動這个複雜 ê 恆星形成區，予伊發出可見光。 這个 300 萬歲 ê 獵戶座星雲 內底 ê 星團，是比伊少年 ê 時陣猶閣較實密。 照 動力學研究 表示講，可能是當初時 失控 ê 恆星相挵，產生一粒 質量超過 100 倍太陽質量 ê 烏洞 。 星團內底若是有 烏洞 ，就會當解說 四邊形星群 內底 ê 恆星是按怎會有遮爾懸 ê 運動速度。 獵戶座星雲 kah 咱 ê 距離差不多有 1500 光年，按呢這粒烏洞真有可能是目前為止 kah 咱地球 上倚 ê 烏洞。

[English] Trapezium: At the Heart of Orion

Near the center of this sharp cosmic portrait, at the heart of the Orion Nebula, are four hot, massive stars known as the Trapezium. Gathered within a region about 1.5 light-years in radius, they dominate the core of the dense Orion Nebula Star Cluster. Ultraviolet ionizing radiation from the Trapezium stars, mostly from the brightest star Theta-1 Orionis C powers the complex star forming region's entire visible glow. About three million years old, the Orion Nebula Cluster was even more compact in its younger years and a dynamical study indicates that runaway stellar collisions at an earlier age may have formed a black hole with more than 100 times the mass of the Sun. The presence of a black hole within the cluster could explain the observed high velocities of the Trapezium stars. The Orion Nebula's distance of some 1,500 light-years would make it one of the closest known black holes to planet Earth.
