Layers of armor protect Earth from the sun's harmful energies, while letting in heat and light that power the climate.
Earth and the planets sit in the crosshairs of multiple streams of solar power. Giant explosions on the sun, called coronal mass ejections, blast electrically charged particles across the solar system, where they are deflected by Earth's strong magnetic field. As the sun endlessly emits solar radiation, a different kind of protective layer—Earth's gaseous atmosphere—shields the planet from harmful rays. But it is the radiation that penetrates the atmosphere and is absorbed by Earth's surface that makes life possible and drives a remarkable planetary engine—the climate. This narrated animation uses NASA satellite and model data to illustrate the fundamental power of the sun and how its energy drives the winds and ocean currents on Earth. It is an excerpt from "Dynamic Earth: Exploring Earth's Climate Engine," a fulldome, high-resolution movie now playing at planetariums around the world.
