PHOTOS: Northern lights dazzle across Saskatchewan
The northern lights were dazzling all across Saskatchewan this weekend.
The lights, or aurora borealis, are caused when the Sun blasts charged particles (electrons and protons) into space, which is called the solar wind, according to the Canadian Space Agency.
When the Earth’s magnetic field protects the planet from the solar wind, the magnetic field lines are dragged and stretched, snapping back like an elastic band, launching charged particles down towards Earth’s surface along the magnetic field lines.
The northern lights occur when these charged particles launched along Earth’s magnetic field collide with gases in Earth’s upper atmosphere.
