Jim Lattis, director of University of Wisconsin’s Space Place, said auroras are caused by charged particles from the sun interacting with gasses like nitrogen in the Earth’s atmosphere. He said a lot of things have to go right for that to happen.
“There are solar flares popping off on the sun every other day or daily these days, but those flares have to emit something that then crosses an awful lot of space between us and the sun, and then actually interacts with the earth,” he said.
