See Manhattanhenge Tonight at Sunset
New York, center of the world, is so important it gets its own astronomical event. Tonight at 8:20pm is Manhattanhenge, when the setting sun aligns with the Manhattan street grid, so that from any city block, it seems to sit on the horizon neatly in the middle of the road. (It looks especially grand on main streets like 14th, 34th, and 42nd.)
This happens twice a year, on two dates straddling the equinox (in 2017 that's May 30 and July 12). On the dates immediately surrounding those two (May 29 and July 13), the sun is in the middle of each block just a touch later, when it's halfway below the horizon, according to Farmer's Almanac (which handily updates its Manhattanhenge guide annually with the year's precise dates).
The same thing happens to the rising sun around December 5 and January 8, but who can be bothered to get up that early?
The whole thing happens, says astrophysicist Neil deGrasse Tyson, because outside the equator, the sun sets at a slightly different location every day:
Crucially, there's a clear view of the horizon past Manhattan, so the sun isn't obscured. While gridded cities like Chicago, Baltimore, Toronto, and Montreal have their own henges , none is quite as stunning as New York's.
Getting a good photo is tough, since you're competing with everyone in New York trying to capture the cosmic interplay of nature and civilization with their damn phones. Just enjoy the moment in real time, and look at everyone's miserable little Instagram pictures later.
