木卫一的真实色彩

英文原文:Explanation: 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 . 说明：太阳系中最奇特的卫星[4]是明亮的黄色。这张主题图像[5]，试图展示木卫一(Io )在一般人眼中可见的「真实颜色」，图像是由伽利略号探测器[6]于1999年7月拍摄的，该探测器于1995年至2003年间环绕木星运行。木卫一的颜色来自硫[7]和熔融的硅酸盐岩石[8]。木卫一的表面[9]因其活跃的火山系统[10]而保持着非常年轻的状态。木星强大的潮汐引力[11]拉伸着木卫一[12]，并抑制了由木星其他伽利略卫星[13]引起的扰动。由此产生的摩擦[14]极大地加热了木卫一[15]的内部，导致熔岩[16]爆发穿透表面。木卫一的火山[17]活动非常活跃[18]，几乎将整颗卫星翻了个底朝天。木卫一的一些火山熔岩[19]温度极高，甚至于它在黑暗中发光。
