Our magnetosphere tells us much about how all the planets act. Since we find the same kinds of plasma measurements happening on other planets, our earth can tell us much about worlds that are far away. This way, we can use our whole planet as a sort of laboratory for the other planets and even for the stars. This not only helps us understand our world but helps us reach out to other worlds at the same time. This makes what we learn around our own planet that much more important.

We also learn things about the world in which we live. The space around the atmosphere is alive and dynamic, not empty and still. Our planet is connected with our sun with more than light. The magnetosphere protects and forms what happens on earth and has done that for millennia. That, in itself, makes it worthy of our attention.
