What is Heliophysics?
The Study of the Sun and its Interaction with Earth and the Solar System is called Heliophysics.
It requires viewing the sun, heliosphere, and planetary environments as elements of a single interconnected system – one that contains dynamic space weather, and that evolves in response to solar, planetary and interstellar conditions.
The role of NASA’s Heliophysics Division is to answer the following questions about this systems behavior.
- - What causes the sun to vary?
- - How do the Earth and the heliosphere respond?
- - What are the impacts on humanity?
