Earth

Our planet, along with the rest of the solar system and some nearby stars, may be trapped inside a giant magnetic tunnel — and astronomers don't know why. 

The proposed giant tunnel is hundred of light years wide, making it big enough to encompass Earth, our solar system, and even nearby stars. © Provided by Live Science The proposed giant tunnel is hundred of light years wide, making it big enough to encompass Earth, our solar system, and even nearby stars.

A tube of vast magnetized tendrils, 1,000 light-years long and invisible to the naked eye, may encircle the solar system, astronomers propose in a new paper. Jennifer West, an astronomer at the Dunlap Institute for Astronomy and Astrophysics at the University of Toronto, made the proposal after an investigation into the North Polar Spur and the Fan Region — two of the brightest radio-emitting gas structures in our galactic neighborhood — revealed that the two structures might be linked even though they are located on different sides of the sky.

"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 a statement

The curving tendrils — which are made of both charged particles and a magnetic field, and resemble long, thin ropes — project outward from the North Polar Spur and the Fan Region. Not only could the strange cosmic ropes link the two regions, but they could form something akin to "a curving tunnel" where the tendrils are like "the lines formed by the tunnel lights and road lane marker," the researchers said. 

This would place our solar system along with a small chunk of the Milky Way, inside the giant magnetic tunnel. 

The North Polar Spur, which appears as an enormous yellow cloud stretching above the plane of our galaxy, is a gigantic crest of gas emitting X-rays and radio waves. The Fan Region is less understood but produces a lot of polarized radio waves. Though these unusual regions in space were discovered in the 1960s, scientific understanding of them remains patchy, and most previous studies described each structure separately.
