Aurora Borealis over Tromso, Norway

An aurora shaped like an eagle or a phoenix is photographed in the above Grotfjord, close to Tromso, Norway.

The image was taken by Arctic photographer Bjorn Jorgensen.

He said: "I knew there was a good chance of Northern Lights that night, but I did not realise it would be so powerful and produce an eruption like that."
