太阳系中最奇怪的卫星是亮黄色的。1999年7月，伽利略号宇宙飞船在1995年至2003年期间环绕木星运行，拍摄了这张特色图片，试图展示木卫一在普通人肉眼可见的“真实色彩”。木卫一的颜色来自硫和熔融的硅酸盐岩石。木卫一不同寻常的表面由于它的活火山系统而保持年轻。木星强烈的潮汐引力拉伸了木卫一，并减弱了木星其他伽利略卫星造成的抖动。由此产生的摩擦极大地加热了木卫一内部，导致熔岩在表面爆炸。木卫一的火山非常活跃，它们实际上把整个卫星都翻了出来。木卫一上的一些火山熔岩非常热，在黑暗中也会发光。阿尔忒弥斯1号报道：猎户座返回并溅落

The strangest moon in the Solar System is bright yellow. The featured picture, an attempt to show how Io would appear in the "true colors" perceptible to the average human eye, was taken in 1999 July by the Galileo spacecraft that orbited Jupiter from 1995 to 2003. Io's colors derive from sulfur and molten silicate rock. The unusual surface of Io is kept very young by its system of active volcanoes. The intense tidal gravity of Jupiter stretches Io and damps wobbles caused by Jupiter's other Galilean moons. The resulting friction greatly heats Io's interior, causing molten rock to explode through the surface. Io's volcanoes are so active that they are effectively turning the whole moon inside out. Some of Io's volcanic lava is so hot it glows in the dark. Artemis 1 Coverage: Orion return and splashdown
