Checking out the stars on a clear night in Boston can be a hard find until now. The Charles Hayden Planetarium at the Museum of Science recently underwent a $9 million facelift where you can now spend an evening out under 9,100 stars in the most technologically advanced digital theater in New England. The surface of the dome is used to project the night sky to offer a virtual experience of flying through the universe. It just doesn’t get any cooler than this.
