Experience the magic of the Northern Lights at Gardens by the Bay's Supertree Grove. From May 4 onwards, a spellbinding outdoor installation called Borealis will light up the Supertrees in a display reminiscent of the polar lights you'd normally have to travel to Iceland, Sweden, or other far-flung regions to witness. It's the work of Switzerland-based artist Dan Acher, who has ingeniously layered light beams and cloud particles to create a mesmerising dance of light and colour. Coupled with an atmospheric score by French composer Guillaume Desbois, Borealis promises to be an out-of-this-world experience. Admission is free – find out more here.
