New York City is rarely the site of stunning astronomical wonders, but twice a year residents and tourists are treated to a special solar event. During Manhattanhenge, the sun sets perfectly along the city's east-west street grid.
The term "Manhattanhenge" was coined in 2002 by astrophysicist Neil deGrasse Tyson in reference to England's Stonehenge, a prehistoric monument known for its mysterious origins and dramatic solstice alignments.
Ever since Tyson brought mainstream attention to Manhattanhenge, hundreds of New Yorkers have established a tradition of gathering along 14th, 23rd, 34th, 42nd, 57th and some parallel streets to witness a stunning skyscraper-framed sunset. This year, the "full sun on the grid" — the absolute best Manhattanhenge experience — was on May 30 at 8:12 p.m. New York time. It comes around again on July 12 at 8:20 p.m., and if you miss that one, you can see a so-called "half sun on the grid" the next day, July 13.
The popularity of the event has spiked in recent years, so observers are encouraged to show up at least a half-hour early to get a good view.
