A vivid green and purple aurora has been caught in a stunning timelapse video in Yellowknife, Canada.
The colourful display of light is a natural electrical phenomenon, commonly referred to as the northern lights.
Every year thousands of tourists visit the Northwest Territories to take in the picturesque views on display.
The location is renowned for the aurora borealis phenomenon, due to its long dark nights.
Captured in 2014, the breathtaking scenes were released by James, a film-maker.
The beautiful show of nature can be seen in the UK, but it is difficult to predict its strength and location.

An aurora can be characterised by the appearance of reddish or greenish light in the sky, especially near the northern or southern magnetic pole.
The spectacular display is caused by the interaction of charged particles from the sun with atoms in the upper atmosphere.
In northern and southern regions it is respectively called aurora borealis or Northern Lights.
