The Sun and the Earth are intimately linked. Discover what scientists have learned about how changes on the Sun trigger events on Earth and how this impacts human exploration of space.
We can learn about how the Earth formed and the forces that change the face of the Earth today by studying the planets of our solar system. Compare what we see here on Earth to the volcanoes on Venus and Mars and the active moons of Jupiter and Saturn in Roadside Geology of the Solar System.
