又去了一个！木星卫星木卫一上的火山一直在喷发。为了进行调查，美国宇航局的朱诺号探测器已经开始对这颗奇怪的卫星进行一系列的访问。木卫一的大小和地球的卫星差不多，但由于木星和其他卫星的引力弯曲，木卫一的内部被加热，表面被火山覆盖。这张特色图片来自上周的飞越，它在这颗危险活跃的星球上空12000公里处飞过。木卫一表面覆盖着硫磺和冰冻的二氧化硫，使其呈现黄色、橙色和棕色。正如人们所希望的那样，“朱诺号”飞过时正好有一座火山正在喷发——在这张特色图片的顶部附近，可以看到微弱的羽状物。研究木卫一上的火山和羽流有助于人类更好地理解木星复杂的卫星、光环和极光系统是如何相互作用的。朱诺号计划在接下来的几个月里两次飞越木卫一，距离近10倍：一次在12月，另一次在2024年2月。招聘：APOD专业天文学家级别的客座作家和助理编辑

There goes another one! Volcanoes on Jupiter's moon Io keep erupting. To investigate, NASA's robotic Juno spacecraft has begun a series of visits to this very strange moon. Io is about the size of Earth's moon, but because of gravitational flexing by Jupiter and other moons, Io's interior gets heated and its surface has become covered with volcanoes. The featured image is from last week's flyby, passing within 12,000 kilometers above the dangerously active world. The surface of Io is covered with sulfur and frozen sulfur dioxide, making it appear yellow, orange and brown. As hoped, Juno flew by just as a volcano was erupting -- with its faint plume visible near the top of the featured image. Studying Io's volcanoes and plumes helps humanity better understand how Jupiter's complex system of moons, rings, and auroras interact. Juno is scheduled to make two flybys of Io during the coming months that are almost 10 times closer: one in December and another in February 2024.
