People are treated to a recreation of the Northern Lights thanks to a laser light art installation in Woolwich, a historic town in the borough of Greenwich, London, on September 10, 2021. /CFP

As part of the Greenwich and Docklands International Festival at Royal Artillery Barracks, the artwork "Borealis" is created by shining high-powered laser beams through clouds of particles that present the "variations in movement, color and density." /CFP

Designed by Dan Acher, the installation, which premiered in 2016, has brought the experience of the Northern Lights to locations all around the world, including Australia, Japan and Switzerland. /CFP
