A rare solar event called Manhattanhenge is set to return to New York City in 2025. It will take place on May 28 and 29. The event happens when the setting sun aligns with Manhattan’s east-west street grid. Many people gather to watch and take pictures of this moment.

What is Manhattanhenge?

Manhattanhenge is when the sun sets directly in line with the city's street grid. The sunlight travels between the buildings. It makes the sun appear in the middle of the streets. People often take photos of this rare event. It happens only a few times each year.

Neil DeGrasse Tyson gave the name Manhattanhenge. He is a science communicator and the director of the Hayden Planetarium, media reports said. The name comes from a comparison to Stonehenge in England. Manhattanhenge happens due to the Earth’s 23-degree tilt. The Earth’s rotation changes the sun's position each day. Twice a year, the sun lines up with the city’s grid. This creates the bright effect in the streets.
