The proposal comes from University of Toronto astronomer Jennifer West, who is basing the hypothesis on two structures in the sky: The North Polar Spur and the Fan Region.

The structures, first observed in the 1960s, were initially documented as being separate, but West and her colleagues found the two form a connection that 'looks like a tunnel around our solar system,' according to a press release.

West and her team provide a simple example to explain the idea: 'A curving tunnel, with lines formed by the tunnel lights and road lane markers, forms a similar geometry to the proposed model of the North Polar Spur and Fan Region.'.

The North Polar Spur is a large ridge of hot, X-ray- and radio-emitting gas that rises above the plane of the galaxy. .

The team is planning on completing even more complex modeling in the future — with the hopes of uncovering and understanding what role the magnetic tunnel plays in the galaxy.
