IU South Bend professor helps us understand meteors

SOUTH BEND, Ind. - Did you know you can tell the size of a meteor in the sky by listening to it? It's called infrasound. 

"If you have an object that comes in and it's heavy, it'll make a loud sound. If it's smaller, it makes a quieter sound," said IU South Bend's Department of Physics and Astronomy professor Brian Davis, Ph.D.

Davis spoke with ABC57's Gordy Young about the live footage of a meteor sparked across the sky and puts to rest any safety concerns.
