The earth, our home in space, is a varied and dynamic place. Since the advent of the aerospace age, we have gained new insights into how our planet works. Today dozens of orbiting satellites reveal structures and patterns on the earth’s surface that have never been seen before.
These satellites carry sensors that allow us to observe oceans, mountains, land surfaces, human activity, and changes in global climate. The images they provide have many important applications, from mapping city streets to understanding long-term climate changes.
Most satellite imagery is used for scientific or technical purposes, but these complex pictures can also be appreciated aesthetically. Satellites detect subtleties and variations that human eyes cannot, providing unique and beautiful views of our planet.
