The sun shines down 42nd Street in New York City at sunset during the biannual occurrence named "Manhattanhenge" in New York July 12, 2009. "Manhattanhenge", named by astrophysicist Neil deGrasse Tyson, occurs when the setting sun aligns itself with the east-west grid of streets in Manhattan, allowing the sun to shine down all streets at the same time.
