The northern lights on demand: Artist Dan Acher bring "Borealis" to Cambridge.

To see the atmospheric phenomenon aurora borealis, or northern lights, most people would have to travel to high-latitude regions around the Arctic or Antarctic. But Swiss artist Dan Acher has created a light installation for people in cities all over the world to experience the brilliant colors as part of an effort to inspire a sense of belonging and community in connection to the environment.

Acher, an Ashoka Fellow and the founder of Happy City Lab, has been commissioned to bring his “Borealis” installation to the 2022 Cambridge Science Festival and display the northern lights above Kendall Square.
