在我們的太陽系中，有一顆非常奇特的月球，它的顏色是亮亮的黃色。這幅有趣的圖片是由伽利略太空船在1999年7月拍攝的，展示了Io的「真實顏色」，這些顏色是我們的眼睛可以看見的。Io的顏色來自於硫和融化的岩石。Io的表面非常不尋常，因為它有著許多活躍的火山，這使得它的表面保持年輕。木星的強大引力讓Io不停地拉伸，還減緩了Io搖晃的現象，這讓它的內部產生了大量的摩擦，導致它的裡面變得非常熱。這樣的熱量讓融化的岩石不斷地在表面爆發出來。Io的火山活動如此頻繁，幾乎讓整顆月球的內部都被翻轉過來。某些Io的火山熔岩是如此的熱，以至於它在黑暗中發光喔！
原文:
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.
