Tonight is the night! (Tomorrow too, as well as 2 more dates in July). If you’re in NYC, make sure to have your phone camera at the ready. If you’re not, don’t worry, I’m sure Manhattanhenge images will flood your feeds later on tonight.

Check out more details from The New York Times:

Each year at the end of May, and again in mid-July, residents and tourists alike flood the streets of Manhattan for a spectacular view of the sun setting in the west, flanked by the city’s famous streetscapes. Nicknamed Manhattanhenge, the event attracts more people each year, some gathering in crowds so dense they block the streets.

“I think of it as astronomy in your face,” said Jackie Faherty, an astronomer at the American Museum of Natural History who computes the dates for Manhattanhenge each year. “It’s like a huge science party that will occur in the city.”

The event’s popularity most likely goes beyond an interest in science, Dr. Faherty added: People love a good photo op, and Manhattanhenge delivers.
