这张由韦伯的近红外相机（NIRCam）于2023年2月6日拍摄的天王星的放大图像显示了该行星光环的壮丽景色。这颗行星在这张代表性的彩色图像中呈现为蓝色色调，这张图像是由1.4微米（显示为蓝色）和3.0微米（显示为橙色）的两个滤波器（F140M、F300M）的数据组合而成。 影像来源：NASA, ESA, CSA, STScI. 影像处理：J. DePasquale (STScI) 继2022年发布的海王星图像之后，NASA的詹姆斯·韦伯太空望远镜拍摄了太阳系另一颗冰巨星天王星的惊人图像。这张新照片展现了引人注目的天王星环以及行星大气层中明亮的特征。韦伯的数据表明，该天文台对最微弱的尘埃环具有前所未有的灵敏度，只有其他两个设施对这些尘埃环进行过成像：1986年旅行者2号飞船飞掠该行星时的成像，以及具有先进自适应光...
