Our senses tell us about the natural world, but our senses cannot tell us everything. That's why we use tools, and NASA develops some of the most sophisticated, most exciting tools of all. Designed to reveal aspects of the Earth, the Sun, The Moon, these tools gather essential data about the world around us, while other instruments peer way out to much more distant places. When these data are turned into visualizations, we discover a complexity and elegance to the natural world that would otherwise elude our physical senses. Even more important, we uncover vital clues to understand how things work, how they're changing, and what the implications for those changes may mean. With the advent of Ultra-High-Definition video, more commonly known as “4K Video”, those images take on an enhanced majesty and power. In this video, we present images about our home planet, as well as the life-giving star it orbits, and the mysterious moon that travels with us through space.
