Manhattanhenge

The sun sets on 42nd Street in New York City during "Manhattanhenge," a biannual occurrence in the busy city on May 30.

"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.
