NASA | The Mystery of the Aurora

Auroras, also known as the Northern Lights, are stunning displays of colored light in the sky, caused by space weather affecting Earth's magnetic field. These phenomena can disrupt power grids and communication systems. Spring is an ideal time to view auroras due to frequent substorms.
