- Pluto Flyover from New Horizons (apod.nasa.gov)
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.

If you had stood atop the highest peak on Hong Kong Island, on January 26, 1841, you could have seen a British naval squadron assembled in the harbor below. With a spyglass, you might have made out the commodore stepping ashore to toast Queen Victoria and declare the island her territory. There were no signs of dissent from the Chinese military or the local villagers, who numbered fewer than 7,500. It was a mild kickoff to what would add up to a century and a half of British rule.
