An astronomer has proposed a bold model suggesting that the entire solar system is surrounded by a massive, magnetic tunnel.

The model focuses on two major structures in the sky: the North Polar Spur and the Fan Region, according to a press release from the University of Toronto.

Jennifer West now suggests that they’re actually a part of a huge, tunnel-like magnetic field surrounding the solar system. .

“If we were to look up in the sky we would see this tunnel-like structure in just about every direction we looked – that is, if we had eyes that could see radio light,” West said in the press release.
