Manhattanhenge feat. Neal deGrasse Tyson

Manhattanhenge is a term given by Neal deGrasse Tyson on American Museum of Natural History’s site to the alignment of streets in the East- West direction in Manhattan, where you can see, twice a year, how the sunset lines up with New York City’s street grid showing spectacular views.

From SciFri:

Neil deGrasse Tyson, director of the Hayden Planetarium in New York, identified the cosmic event over a decade ago and coined it Manhattanhenge. In this video from 2009, we watched the sun from 42nd Street, along with about 50 other astronomical enthusiasts.

Neil asks:

What will future civilizations think of Manhattan Island when they dig it up and find a carefully laid out network of streets and avenues? Surely the grid would be presumed to have astronomical significance, just as we have found for the pre-historic circle of large vertical rocks known as Stonehenge, in the Salisbury Plain of England. For Stonehenge, the special day is the summer solstice, when the Sun rises in perfect alignment with several of the stones, signaling the change of season.
