THEMIS and Auroras
Auroras or known as the Northern lights, visible in North America, are fascinating colorful weather phenomena. Called substorms, these are solar energy that interact with the earth’s weather system, thus resulting in those beautiful auroras. NASA’s THEMIS Mission (Time History of Events and Macroscale Interactions during Substorms) has made important discoveries regarding this weather phenomenon.
