这是土星的卫星土卫一(米玛斯)上赫歇尔环形山的假彩色照片，由NASA的卡西尼飞船在最接近土卫一飞行的时候拍摄，照片上细微的颜色差别很明显。
Subtle color differences on Saturn's moon Mimas are apparent in this false-color view of Herschel Crater captured by NASA's Cassini spacecraft during its closest-ever flyby of that moon.
土卫一“米玛斯”是土星最里面的卫星之一，也是“卡西尼”号的一个重点观测目标。由于表面的巨大环形陨坑，土卫一看上去好似一只牛眼。
Mimas, one of Saturn's innermost moons, was another of Cassini's targets--which is fitting because Mimas looks rather like a bulls-eye, thanks to the huge circular crater on its surface.
