1986年，旅行者2号成为唯一近距离探索冰巨行星天王星的航天器。尽管如此，这张由詹姆斯韦伯太空望远镜上的NIRCam（近红外相机）最新发布的图像提供了对遥远世界的详细观察。倾斜的外行星每17小时绕其轴旋转一次。它的北极目前指向我们的视线附近，可以直接看到它的北半球和一个微弱但广泛的环系统。在这颗巨大行星已知的27颗卫星中，有14颗在图像中标注。与模糊的背景星系混合在一起，明亮的卫星显示出韦伯特有的衍射峰的迹象。尽管这些太阳系外的世界在莎士比亚时代还不为人所知，但天王星的27颗卫星中，只有两颗以这位英国吟游诗人戏剧中的人物命名。

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.
