Art lovers have been treated to a recreation of the Northern Lights thanks to a spectacular laser show.
The artwork Borealis, by Dan Acher, appeared over the south London skies as part of the Greenwich and Docklands Intentional Festival.
According to Acher’s Happy City Lab website: “Variations in movement, colour, and density, together with changing weather conditions, give infinite variations.
The installation, which premiered in 2016, has appeared in locations all around the world, including Australia, Japan and Switzerland.
