Mysterious Sounds made by the Aurora
Scientists discover where the mysterious sounds of the Northern Lights are generated. The strange crackling noises of the Aurora Borealis have been explained by researchers at the Aalto University in Finland, and that they form about 70 meters above the ground.

“In the past, researchers thought that the aurora borealis was too far away for people to hear the sounds it made,” said Unto K. Laine from Aalto University in Finland. “However, our research proves that the source of the sounds that are associated with the aurora borealis we see is likely caused by the same energetic particles from the Sun that create the northern lights far away in the sky. These particles or the geomagnetic disturbance produced by them seem to create sound much closer to the ground.”
