太空中的莎士比亞
Shakespeare in Space

1986 年,航海家 2 號成為唯一一個近距離探索冰巨行星天王星的太空飛行船。儘管如此,詹姆斯-韋伯太空望遠鏡(James Webb Space Telescope)上的近紅外相機(NIRCam)最新發布的這張圖片還是為我們提供了這個遙遠世界的詳細情況。這顆傾斜的外行星大約每 17 個小時自轉一圈。它的北極目前正對著我們的視線,可以直接看到它的北半球和一個微弱但龐大的星環系統。在這顆巨行星的 27 顆已知衛星中,有 14 顆在影像中標註。與模糊的背景星系混雜在一起,亮度較高的衛星顯示出韋伯特有的衍射尖峰。雖然這些太陽系外的世界在莎士比亞時代還不為人所知,但除了兩顆以外, 27 顆天王星衛星都是以英國吟遊詩人戲劇中的人物命名的。
原文:In 1986, Voyager 2 became the only spacecraft to explore ice giant planet Uranus close up. Still, this newly released image from the NIRCam (Near-Infrared Camera) on the James Webb Space Telescope offers a detailed look at the distant world. The tilted outer planet rotates on its axis once in about 17 hours. Its north pole is presently pointed near our line of sight, offering direct views of its northern hemisphere and a faint but extensive system of rings. Of the giant planet's 27 known moons, 14 are annotated in the image. Mixed with fuzzy background galaxies, the brighter moons show hints of Webb's characteristic diffraction spikes. And though these worlds of the outer Solar System were unknown in Shakespearean times, all but two of the 27 Uranian moons are named for characters in the English bard's plays.
