原文:
As spring comes to planet Earth’s northern hemisphere, familiar winter constellation Orion sets in early evening skies and budding trees frame the Hunter’s stars. The yellowish hue of cool red supergiant Alpha Orionis, the great star Betelgeuse, mingles with the branches at the top of this colorful skyscape. Orion’s alpha star is joined on the far right by Alpha Tauri. Also known as Aldebaran and also a giant star cooler than the Sun, it shines with a yellow light at the head of Taurus, the Bull. Contrasting blue supergiant Rigel, Beta Orionis, is Orion’s other dominant star though, and marks the Hunter’s foot below center. Of course, the sword of Orion hangs from the Hunter’s three blue belt stars near picture center, but the middle star in the sword is not a star at all. A slightly fuzzy pinkish glow hints at its true nature, a nearby stellar nursery visible to the unaided eye known as the Orion Nebula.

隨着春天來臨，地球北半球的冬季星座獵戶座在早晚的天空中潛下，嫩芽的樹枝框住了這位獵人的星星。冷紅超巨星的黃色光芒，亦即是獵戶座的「貝塔爾吉斯」(Betelgeuse)，在這幅多彩的星空圖中與樹枝交融。獵戶座的亮星在右側則是「阿爾德巴朗」(Aldebaran)，也就是金牛座的阿爾法星，它是顆比太陽更涼的巨星，發出黃色的光輝，矗立在金牛座的頭部。而獵戶座的另一顆主要星星是藍色超巨星「里傑爾」(Rigel)，標記著獵戶的腳部，位於中央下方。獵戶座的三顆藍色帶星懸掛着獵戶的劍，但其劍中的中間星不是一顆星，而是一抹略微模糊的粉紅色光暈，隱約提示它的真正本質：一個鄰近的星際產房，即獵戶星雲(Orion Nebula)，可用肉眼清晰可見。
