A cool semi annual celestial event made popular by braniac Neil deGrasse Tyson is commonly referred to as Manhattenhenge. For those of you not familiar with the event, the same planetary tilt that determines the seasons also dictates exactly where the sun will go down each evening — and because of the way that Manhattan’s dominant street grid is laid out, killer sunsets are potentially visible from some of the borough’s best-known east-west streets in late May and mid-July. New Yorkers were wowed on Wednesday night by a sunset that was perfectly framed by skyscrapers.
