The nightime display could be seen across Scotland, Canada, Norway and even the north-east of England last week after the biggest solar storm in more than six years bombarded the earth with radiation. One flyer caught the natural phenonmenon, called aurora borealis, as it lit up the wings of a transatlantic Air Canda flight. The wings glowed red as green lit up the horizon.
Spectacular: An aeroplane's wing is lit up by the Northern Lights. The Air Canada flight was heading over the Atlantic when a passenger took this spectacular photo.
Natural beauty: These rare green and blue northern lights were photographed over the city of Grundarfjorour in Iceland.
Eerie: A green aurora appears over Svalbard in Norway, an area close to the north pole which is shrouded in darkness for much of the year.
Husky's delight: A rare pink sky over Svalbard, Norway. The spectacular sight only occurs once in every five years.
Awe-inspiring: The dramatic pink sky was caused by freak high clouds that were pushed up by low pressure air, so they rose over the curvature of the earth and were hit by sunlight.
Dedication: German-born Kerstin has snow-shoed and dog-sleighed her way up some of Scandinavia's most spectacular mountains to get the perfect picture.
