In early 2008, scientists found the trigger for Northern Lights. Researchers working at NASA studied magnets in our solar system. More specifically, they launched a mission to understand the interplay of magnetic fields and charged particles blown outward from the Sun. This mission was known as The Themis Mission. The Themis Mission launched five identical satellites to track magnetism in space. Northern lights are generated by charged particles flying from the Sun and interacting with the Earth’s magnetic field, it is the satellites job to monitor these particles.

These particles do more than create northern lights. They also control space storms, by finding out how they work scientists at NASA can pilot through space safely.
