The upper layer of the Earth's atmosphere could play a bigger role in shaping the northern lights than previously thought, University of Iowa researchers show.

When these waves of charged particles reach Earth, they interact with the planet’s magnetic field, triggering the stunning displays of color known as the aurora borealis in the north and the ...

concerning the correspondence of the Earth's magnetic field micropulsations 1 with pulsating aurora for the purpose of explaining the physical mechanism giving rise to the phenomena. Fig.

My mom, who’d agreed to join my winter aurora ... protective magnetic shield stores this energy until there’s too much of it, then boom—the particles zip down the magnetic field lines ...

Aurora results from interactions between the solar wind and Earth’s magnetic field. Most displays are down to geomagnetic storms caused by an intense solar wind powered by coronal mass ejections.

However, the electrojets create a magnetic field that can split apart that 118 gigahertz emission line in a process called Zeeman splitting. The stronger the magnetic field, the farther apart the ...
