Aalto University, a Finnish Meteorological Institute, released a statement indicating their research proves the source of sounds associated with aurora borealis, some have referred to them as claps, is likely caused by the same energetic particles from the sun that create the northern lights far away in the sky.

With three microphones set up at a site with high auroral activity, Laine and his colleagues determined the location of the clapping noise by comparing sounds captured by the listening devices. “In the past, researchers thought that the aurora borealis was too far away for people to hear the sounds it made,” Unto Laine, from Aalto University in Finland, said in a statement released Monday. Yet, scientists have yet to prove exactly how the auroral sounds are created.

The new study will be published in the proceedings of the 19th International Congress on Sound and Vibration, a conference that’s meeting in Vilnius, Lithuania from Sunday to Thursday.
