Known as the aurora borealis, the phenomenon is usually best viewed in the north of Norway.

Almost a decade after Reykjavik was forced to reinvent itself, it remains wonderfully weird, perhaps more than ever, writes Cynthia Rosenfeld.

Everyone is encouraged to keep a close eye on the north horizon over the next few nights as the northern lights are expected to be visible.

Photographer Noel Keating has released a powerful video detailing his struggle to capture the beautiful aurora borealis off the Donegal coast.

People have been sharing their pictures on social media and they're stunning.

Felipe Pitta made a pilgrimage to the Arctic Circle to capture the magic of the aurora. This incredible short film is the result.
