Twice a year, New Yorkers and visitors are treated to a phenomenon known as Manhattanhenge, when the setting sun aligns with the Manhattan street grid and sinks below the horizon framed in a canyon of skyscrapers. The first Manhattanhenge of the year takes place Wednesday at 8:13 p.m., with a slight variation happening again Thursday at 8:12 p.m. It will occur again on July 11 and 12. Astrophysicist Neil deGrasse Tyson coined the term in a 1997 article in the magazine Natural History.
