The Northern Lights are seen when the solar wind stream hits Earth’s magnetic field, sparking bright auroras around the Arctic Circle. In northern latitudes, the effect is known as the Aurora Borealis, named after the Roman goddess of dawn, Aurora, and the Greek name for north wind, Boreas, by Pierre Gassendi in 1621. The aurora borealis is also called the northern polar lights, as it is only visible in the sky from the Northern Hemisphere, with the chance of visibility increasing with proximity to the North Magnetic Pole.
These shots were taken by photographer Bjorn Jorgensen who lives in Tromso in northern Norway.
Bjorn said: “I try to capture the essence of the artic light, and I am particulary obsessed with the Aurora Borealis, or Northern Lights. This breathtaking phenomenon has always left people awestruck, and it has inspired artist and scientists for hunderds of years.
It’s challenge to capture good images of the aurora, not only technically, one must also be prepared to spend several freezing nights alone in the dark wilderness.”

was taken yesterday night close to the city Tromso in North Norway. We start whit that photos:

This photo is taken in March, early at night, so the orange clour from the sunset is still visible. The bright colour from the Aurora reflects in the fjord, making half of the fjord green. The bright white star is actually the planet Venus. From Ersfjord close to Tromso, North Norway

A small village called Grotfjorden by the open sea. From the island Kvaloya close to Tromso.

Very strong auroras on this night in March 2008. I waited for an hour, when suddenly the sky exploded in green, and it was all over in fifteen minutes. From the fjord Ersfjord close to Tromso.

This photo was taken in September 2008, in the Lofoten islands. It was early at night, so the colours from the sunset were still visible.

This photo from the island Kvaloya close to Tromso, North Norway, was shot in October 2003, during one of the most powerful outbursts of Northern Lights ever registered.
