New York:
New York City residents and visitors look up at the sky to experience a phenomenon twice a year known as Manhattanhenge.
The setting sun was framed by a canyon of skyscrapers Thursday as it sunk below the horizon, perfectly aligned with the Manhattan street grid.
The dramatic spectacle was just the first of the year. Another version of the setting sun is possible between New York’s famed skyscrapers on Friday. The phenomenon then repeats on July 11 and 12.
Manhattanhenge happens about three weeks before and after the summer solstice.
Over the years, it has become a must-see event, bringing photographers and others out onto the city sidewalks on spring and summer evenings.
Some background on the uniquely New York experience:
Astrophysicist Neil deGrasse Tyson coined the term in a 1997 article in the magazine “Natural History.” Tyson, the director of the Hayden Planetarium at New York’s American Museum of Natural History, said he was inspired by a visit to Stonehenge as a teenager.
The future host of TV shows such as PBS’ “Nova ScienceNow” was part of an expedition led by Gerald Hawkins, the scientist who first theorized that Stonehenge’s mysterious megaliths were an ancient astronomical observatory.
It struck Tyson, a native New Yorker, that the setting sun framed by Manhattan’s high-rises could be compared to the sun’s rays striking the center of the Stonehenge circle on the solstice.
Unlike the Neolithic Stonehenge builders, the planners who laid out Manhattan did not mean to channel the sun. It just worked out that way.
Manhattanhenge does not take place on the summer solstice itself, which is June 21 this year. Instead, it happens about three weeks before and after the solstice. That’s when the sun aligns itself perfectly with the Manhattan grid’s east-west streets.

Viewers get to choose between two different versions of the phenomenon.
On Thursday, and again on July 12, half the sun is above the horizon and half below it at the moment of alignment with Manhattan’s streets, according to the Hayden Planetarium.
On Friday and July 11, the whole sun can appear to hover between buildings just before sinking into the New Jersey horizon across the Hudson River.
The traditional viewing spots are along the city’s broad east-west thoroughfares: 14th Street, 23rd Street, 34th Street, 42nd Street and 57th Street.
The farther east you go, the more dramatic the vista as the sun hits building facades on either side of the street. It is also possible to see Manhattanhenge across the East River in the Long Island City section of Queens.
No, not really.
Seeing Manhattanhenge is mostly a DIY affair. People gather on east-west streets a half-hour or so before sunset and snap photos as dusk approaches. That’s if the weather is fine. There’s no visible Manhattanhenge on rainy or cloudy days.
Similar effects occur in other cities with uniform street grids. Chicagohenge and Baltimorehenge happen when the setting sun lines up with the gridded streets in those cities in March and September, around the spring and fall equinoxes. Torontohenge occurs in February and October.
But Manhattanhenge is particularly striking because of the height of the buildings and the unobstructed path to the Hudson River.
