Scientists predict that 2024 will be a particularly good year for seeing northern lights. The lights that paint the Nordic skies with unexpected colours that dance as if they were moving through the air will, they say, reach places where they are not normally seen, which means that in the places where they are usually sighted, they will have unprecedented power.
Northern lights occur when particles emitted by the sun's radiation collide with the earth's magnetic field. These particles are attracted by the magnetic force towards the poles and on their way collide with oxygen and nitrogen atoms, which produce flashes of light that human eyes perceive in brilliant colours ranging from green to pink.
