It happened on July 12 -- a New York City event known as “Manhattanhenge,” when the sun sets in perfect alignment with the streets of Manhattan. And as usual, huge crowds of tourists joined Manhattanites to get a glimpse of the phenomenon, according to the Association of Mature American Citizens [AMAC]. They gathered on the East side of town facing due West to watch the sun as it made its descent beyond the Hudson River, its rays falling perfectly between Manhattan’s sky scrapers. It happens each year for two days in May and two days in July. Astrophysicist Neil deGrasse Tyson came up with the moniker, Manhattanhenge, comparing it to Britain’s Stonehenge.
