During its close flyby of Jupiter’s moon Io on December 30, 2023, NASA’s Juno spacecraft captured some of the most detailed imagery ever of Io’s volcanic surface. In this image, taken by the JunoCam instrument from about 930 miles (1,500 kilometers) above the moon, Io’s night side is illuminated by “Jupitershine,” which is sunlight reflected from the planet’s surface.
This image is the NASA Science Image of the Month for October 2025. Each month, NASA’s Science Mission Directorate chooses an image to feature, offering desktop wallpaper downloads, as well as links to related topics, activities, and games.

在2023年12月30日对木星的卫星木卫一（Io）进行近距离飞掠期间，NASA的朱诺号（Juno）探测器捕捉到了迄今为止最清晰的木卫一火山地表图像之一。这张照片由朱诺号上的朱诺相机（JunoCam）拍摄，当时探测器距离木卫一表面约930英里（约1500公里）。图中左侧的暗面为木卫一的夜面，由木星照（Jupitershine）——即来自木星表面反射的阳光——所照亮。
这幅图像被评为NASA 2025年10月的本月科学图像。NASA科学任务理事会每月会精选一张图像进行展示，提供桌面壁纸下载，并附有相关主题、活动与互动游戏的链接。
