The researchers use the Earth map as a smaller-scale example of their theory.
A team of astronomers suggests that the solar system is surrounded by a Magnetic tunnel Which can be seen by radio waves, as revealed in a recent study published in the Astrophysical Journal.
According to Jennifer West, a researcher at the University of Toronto (Canada) and lead author of the study, her theory is based on the presence of two bright structures located on either side of the sky, called the Arctic Circle and the fan area. Astronomers have known the two structures for decades, but most studies have focused on them separately. West and his colleagues, however, believe so Connected And is made of charged particles and a magnetic field in the form of long strings. This connection, in turn, creates what appears to be a huge tunnel around our solar system.
“If we looked up at the sky, we would see the tunnel-like structure in almost every direction,” West says. “Sure, if we had eyes that could see the light from radio waves,” he clarifies.
West uses the map of the earth as a smaller example of his theory. On our planet, the North Pole is at the top and the equator is in the middle, unless you look at it from a different perspective. West believes the same is true of our galaxy map.
“Most astronomers look at a map with the north pole of the galaxy facing upwards and the galactic center in the middle. An important part that inspired this idea was Recover this map With a different point of view in between, “he explains.
In this way, using models and simulations, the researchers determined that the two structures are approximately 350 light years Of the earth and have a length of approx 1,000 light years, “The equivalent of a trip between Toronto and Vancouver Two billion times“.
In West’s view, “magnetic fields do not exist in isolation,” everything Must connect Each.
“So the next step is to better understand how this local magnetic field connects to the larger-scale galactic magnetic field and also to the smaller-scale magnetic fields of our Sun and Earth,” the astronomer adds.
For his part, one of the study’s authors, Brian Gansler, acknowledges that “this is a work Extremely smart“And that at first he thought ‘it’ was out of place ‘to be a possible explanation’, but eventually the idea convinced him and that now he is excited to see how the rest of the astronomical community reacts.
