People in parts of Scotland, Northern Ireland, Ireland and along England’s north east coast were treated to a dazzling display of the northern lights on Sunday night.
Also known as the aurora borealis, the lights appear in a ring shape creating a glowing curtain across the sky. According to our insiders’ guide to the northern lights:
This glow is caused by high-energy electrons colliding with oxygen atoms and nitrogen molecules. The basic process is the same as that of a neon sign, which involves a vacuum and a high voltage electrical discharge.
The electric power is generated by a combination of the solar wind, a hot ionized gas blowing out from the sun, and the Earth’s magnetic field. This produces more than 1,000 times the electrical power of the world’s largest power plant.
Images shared by skygazers on Twitter suggest that Sunday’s spectacle was also visible from parts of US, particularly the east coast, and Iceland.
