Bottom line: When charged particles from the sun strike atoms in Earthâs atmosphere, they cause electrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights.
Beyond science. The unearthly beauty of the aurora borealis (Northern Lights) mesmerises all who stay or travel in Polar Regions. Like most natural phenomena, it has a prosaic explanation: It is caused by electrically charged particles, high in energy, entering the Earthâs atmosphere.ne of your best chances of experiencing the Northern Lights is on a Hurtigruten voyage in the winter season. In fact, we're so confident that we have issued a Northern Lights Promise for our 12-day voyages between October and February.
