中文翻譯:
在奧里翁星座的核心，有一個燦爛的星群叫做Trapezium。這裡有四顆明亮的星星，像閃亮的寶石，讓整個空間都充滿了光彩。它們的年齡大約有三百萬年，就像一個三歲大的小朋友，正在快速成長。Trapezium最亮的星星叫做Theta-1 Orionis C，它的光芒強烈，像太陽一樣，讓周圍的氣體發出奇妙的顏色，這裡就是著名的獵戶座星雲（Orion Nebula）。這個星雲的距離地球大約有一千五百光年，因此它是離我們最近的黑洞候選者之一。科學家們告訴我們，這裡也可能隱藏著一個質量超過一百個太陽的黑洞，這讓Trapezium的星星們移動得非常快速，充滿了神秘的魔力。真是一個引人入勝的宇宙故事！
原文:
What lies in the heart of Orion? Trapezium: four bright stars, that can be found near the center of this sharp cosmic portrait. Gathered within a region about 1.5 light-years in radius, these stars 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 make it one of the closest candidate black holes to Earth.
