The local newspaper has published the passage below.

Last week, scientists released incredible images of aurora australis, known as the northern lights. The images show a beautiful display of lights. These lights are the result of the solar activity known as solar wind. The particles of the solar wind flow along the lines of Earth’s magnetic field and collide with gas atoms in Earth’s atmosphere. Light is given off as a result of these collisions. Traces of solar wind reach well beyond Earth and have been detected as far as Saturn.

Which statement is inaccurate?

Solar wind particles flow along the lines of Earth’s magnetic field.
Light is given off when solar wind particles and gas atoms collide.
The aurora australis is known as the northern lights.
Solar winds reach well beyond our planet.
