People across the Northern Hemisphere have been enjoying the celestial display of the Aurora Borealis - or Northern Lights.
The phenomenon is caused by eruptions on the surface of the Sun, and this most recent activity has been unexpectedly strong.
People in the north of the United Kingdom have been sending the BBC images of the light show, as they saw it on Tuesday night.
