Manhattanhenge Returns

News posts

Manhattanhenge makes its final appearance for the year this Friday and Saturday, July 11 and 12.  Here is what you need to know: 

What is Manhattanhenge?

Director of the Hayden Planetarium Neil deGrasse Tyson, who discovered the phenomenon and coined the term “Manhattanhenge,” explains in his Hayden Planetarium blog, that Manhattanhenge takes place “when the setting Sun aligns precisely with the Manhattan street grid, creating a radiant glow of light across Manhattan’s brick and steel canyons, simultaneously illuminating both the north and south sides of every cross street of the borough’s grid." It is, he says, "a rare and beautiful sight.”


When does it take place?

The full Sun can be seen on the horizon on Friday, July 11, at 8:24 pm. On Saturday, July 12, at 8:25 pm, half of the setting Sun can be seen from the grid.

Where’s the best place to see it?

The best views are from the grid on the eastern side of Manhattan (looking toward New Jersey). Cross-streets including 14th, 23rd, 34th, 42nd, and 57th offer good views. The Empire State Building and Chrysler Building at 34th and 42nd make striking backdrops for photos.

How can I learn more about Manhattanhenge?

On Friday, July 11 at 7 pm the Museum will host a Manhattanhenge program in the Hayden Planetarium about the astronomy behind this event.
