A reflective 100-foot-tall hot-air balloon is currently soaring over Massachusetts, from Martha’s Vineyard to the Berkshires. Made of nylon with a reflective mylar coating, the balloon is a floating art installation called “New Horizon” meant to reflect the landscape of Massachusetts and created by renowned artist Doug Aitken.

The event, happening over the course of 16 days, started on July 12. It is currently continuing its journey over Massachusetts by flying to different properties owned by the Trustees of Reservation, including Castle Hill in Ipswich, Field Farm in Williamstown, and Naumkeag House and Gardens in Stockbridge.

“New Horizon is a 21st-century version of a journey,” the Trustees’ website says, “traveling through the landscape by air. The project is composed of a series of live events across the state of Massachusetts. At each stop, the mirror balloon touches down becomes a happening. It is both an artwork and an event where ideas, conversation, music, and art are shared.”

The balloon’s flight path and performance schedule can be found online.
