What causes the Northern Lights? Aurora borealis explained
The aurora borealis, also known as the northern lights, is caused by solar storms on the Sun’s surface heating up the atmosphere and molecules in the Earth’s magnetic field. The colours of the aurora are determined by the gases present, such as oxygen and nitrogen, and can be seen in the UK if the conditions are right.

Aurora borealis: How northern lights are created has now been …
The aurora borealis, or northern lights, is a natural light display caused by the interaction of the solar wind and the Earth’s magnetic field and atmosphere. Researchers at the University of Iowa have now found that the most brilliant auroras are made by powerful electromagnetic waves during geomagnetic storms, similar to a surfer catching a wave.

19 oct. 2023Auroras are natural light displays that shimmer in the sky, caused by solar wind interacting with Earth’s magnetic field. They are only visible at night, usually near the Arctic and Antarctic Circles, and have different colors depending on the kind of atoms involved. Learn more about the causes, colors, and effects of auroras, and see images and facts.
