What is heliophysics?
Heliophysics is the integrated study of the Sun, its planets, and space environment as a dynamic system. It focuses on the Sun's turbulent magnetic activity and its effects on the upper atmosphere of Earth, as well as on other solar system planets and the surrounding heliosphere.
It encompasses many areas of inquiry: cosmic rays and particle acceleration, space weather and radiation, dust and magnetic reconnection, solar activity and stellar cycles, aeronomy and space plasmas, magnetic fields and global change, and the interactions of the solar system with our galaxy.
How does it benefit us?
Heliophysics has great value for two reasons. It is critical in understanding space weather and its potentially crippling impacts on our vital technologies: our satellites, communications and navigation signals, and power grids. This understanding guides our mitigation strategies.
Heliophysics also teaches us about habitability. In studying the Sun’s changing effects on planetary atmospheres, we can learn by proxy about another star’s effects on the atmospheres of its exoplanets. This knowledge will support our search for life elsewhere in the universe.
