Can't make it to Stonehenge? Well, if you can get to New York City by tonight, you can catch Manhattanhenge instead. Tonight is the last night of the twice-annual event, in which the sun perfectly aligns with the Manhattan skyscrapers so you can watch it set along the east-west streets between the buildings. Gothamist has viewing advice from Neil deGrasse Tyson, who named the event; it starts at 8:25pm:
"For best effect, position yourself as far east in Manhattan as possible. But ensure that when you look west across the avenues you can still see New Jersey," Tyson says. "Clear cross streets include 14th, 23rd, 34th. 42nd, 57th, and several streets adjacent to them. The Empire State building and the Chrysler building render 34th street and 42nd streets especially striking vistas."
