Seems like just yesterday we were readying our cameras for the annual Manhattanhenge dates, and here we are again. This weekend, astrophysicist Neil deGrasse Tyson (and director of the Hayden Planetarium in the Department of Astrophysics at the American Museum of Natural History) posted the 2012 dates. If you somehow still haven't heard of the event, here's the deal: four times a year, "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." Two of these days you get the full sun, and the other two you get a half sun (both pictured above).

So without further ado, here are your 2012 Manhattanhenge dates:

Half-sun on the grid
Tuesday, May 29th, 8:17 p.m.
Thursday, July 12th, 8:25 p.m.

Full-sun on the grid
Wednesday, May 30th, 8:16 p.m.
Wednesday, July 11th, 8:24 p.m.

For the uninitiated, deGrasse also has some tips for those who want to score some sweet photos.
