原文:
Beautiful, luminous decorations on this pinyon pine tree are actually bright stars in the constellation Scorpius and the faint glow of the central Milky Way. Captured in June from the north rim of the Grand Canyon of planet Earth, the shallow, close focus image has rendered pine needles on the tree branch sharp, but blurred the distant stars, their light smeared into remarkably colorful disks. Of course, temperature determines the color of a star. Most of the out-of-focus bright stars of Scorpius show a predominately blue hue, their surface temperatures much hotter than the Sun’s. Cooler and larger than the Sun, and noticably redder on the scene, is giant star Antares at the heart of the scorpion. In focused, telescopic views the whitish disk at the upper right would be immediately recognizable though, reflecting the Sun’s light as ringed gas giant Saturn.

在這個美麗的畫面中，裝點著的皮嵐松樹木，其實是蠍子座中明亮的星星，還有中央銀河的微弱光芒。這幅照片是在地球的峽谷北緣於六月拍攝的，淺景深的近焦影像令樹枝上的松針銳利可見，而遠處的星星則變得模糊，光線呈現出色彩斑斕的圓盤。當然，星星的顏色與溫度有關。大多數模糊的蠍子座明亮星星顯現出主要的藍色調，因為它們的表面溫度比太陽高。而比太陽冷卻而且更大的紅超巨星心臟，正是蠍子座的心臟——巨大恆星Antares。在上方右側的白色圓盤則是明顯的氣體巨行星——土星，從聚焦的望遠鏡觀察中，可以立刻認出它的光輝。
