We waited nearly a decade for this image.
After traveling for nine years and covering more than three billion miles, NASA’s New Horizons spacecraft swept past Pluto at over 30,000 miles per hour. It was the first time humanity had ever visited the distant dwarf planet — and the images it returned were unlike anything scientists expected.
Captured just 7,800 miles (12,550 kilometers) above Pluto’s surface, one photograph revealed a frozen landscape bordered by sharp, towering peaks. Some of the mountains reached 11,000 feet (3,350 meters) high, made not of rock, but of solid water ice. At Pluto’s frigid temperatures — nearly −390°F (−235°C) — water behaves like stone.
The shot stunned mission scientists.
Pluto had long been imagined as geologically dead — a frozen relic from the early solar system. But these mountains suggested active geology. To form such sharp features, the surface must be relatively young. Erosion, impacts, and space weathering should have worn them down if they were ancient.
Even more surprising was what surrounded them: a vast, flat basin of nitrogen ice now known as Sputnik Planitia. With no visible craters, it appeared to be actively resurfacing — hinting at internal heat sources and complex planetary processes.
Pluto, once thought of as little more than a cold, distant rock, turned out to be dynamic, layered, and still evolving.
