如果你能飞过冥王星，你会看到什么？2015年7月，新视野号飞船以每小时约8万公里的速度飞过这颗遥远的星球时就做到了这一点。这一壮观通道的图像经过了彩色增强、垂直缩放和数字组合，形成了两分钟的延时视频。当你的旅程开始时，被认为是由水冰组成但被冰冻的氮着色的山脉上出现了曙光。很快，在你的右边，你会看到一个平坦的海洋，大部分是固体氮，它被分割成奇怪的多边形，被认为是从相对温暖的内部冒出来的。火山口和冰山是下面常见的景观。这段视频在被称为叶片地形的地形上变暗并结束，因为它显示了500米高的山脊被数公里大小的裂缝隔开。机器人“新视野号”宇宙飞船的动量太大，无法返回冥王星，现在正驶离太阳系。

What if you could fly over Pluto -- what might you see? The New Horizons spacecraft did just this in 2015 July as it shot past the distant world at a speed of about 80,000 kilometers per hour. Images from this spectacular passage have been color enhanced, vertically scaled, and digitally combined into the featured two-minute time-lapse video. As your journey begins, light dawns on mountains thought to be composed of water ice but colored by frozen nitrogen. Soon, to your right, you see a flat sea of mostly solid nitrogen that has segmented into strange polygons that are thought to have bubbled up from a comparatively warm interior. Craters and ice mountains are common sights below. The video dims and ends over terrain dubbed bladed because it shows 500-meter high ridges separated by kilometer-sized gaps. The robotic New Horizons spacecraft has too much momentum to ever return to Pluto and is now headed out of our Solar System.
