NASA heliophysics research studies a vast system stretching from the Sun to Earth to far beyond the edge of the planets. Studying this system - much of it driven by the Sun's constant outpouring of solar wind - not only helps us understand fundamental information about how the universe works, but also helps protect our technology and astronauts in space. NASA seeks knowledge of near-Earth space, because - when extreme - space weather can interfere with our communications, satellites, and power grids.
