NASA’s Heliophysics Science Division

Nasa’s Heliophysics Science Division conducts research on the sun, its extended solar-system environment (the heliosphere), and interactions of Earth, other planets, small bodies, and interstellar gas with the heliosphere. Division research also encompasses geospace — Earth’s uppermost atmosphere, the ionosphere, and the magnetosphere — and the changing environmental conditions throughout the coupled heliosphere (Solar System weather).National Aeronautics and Space Administration, Goddard Space Flight Center
