Northern lights activity is sky-high, and scientists say more is yet to come

An increase in space weather could lead to the greatest display of the northern lights in the past two decades.
An illustration that shows how northern lights are created. The sun, during coronal mass ejections, emits particles that are carried outward by solar wind. Most of those particles are deflected by the Earth’s magnetic field. Some make it through the field and get trapped; those particles find escape where the magnetic field is weakest at the North Pole and South Pole. When the escaped particles collide with the upper atmosphere, auroral lights are created.
