These incredible pictures show the Northern Lights over the rooftops of Stockholm.
Astro-photographer Alessandro Merga, 24, captured the awe-inspiring sight of the aurora borealis over the Swedish capital of Stockholm.
Mr Merga captured the stunning images from the roof of the Hilton Slussen Hotel which offers a great view of Stockholm’s old town.
He said: “The lights were absolutely amazing. They first appeared over the city as a faint green halo, then they lit up and started to move.”
The lights are a common sight in northern Sweden, but around once a month they can be seen over the streets of Stockholm.
Mr Merga photographed the phenomenon, which lasted for ten minutes, on January 2.
He said: “I didn’t have much time to photograph the lights so I took as many pictures as possible, hoping that at least some were usable.”
The lights are caused by charged particles entering Earth’s atmosphere from space.
