Manhattanhenge? What is this phenomenon? If you are asking this question, you are either a newbie in New York or you avoid all things related to astronomy. According to Neil deGrasse Tyson, the popular director of the Hayden Planetarium, tonight's the night to see this odd metropolitan sunset. Place yourself in one of New York's intersections around 8 p.m. to witness the sunset.

Manhattanhenge, a portmanteau of Manhattan and Stonehenge, is when the setting sun aligns perfectly with Manhattan's famous east-west grid. So you can see the sun go down the horizon down the street of your choosing on New York's most famous island.

The term Manhattanhenge was coined by the astrophysicist Neil deGrasse Tyson, the director of the Hayden Planetarium at the American Museum of Natural History. He is the public face for astronomy as he has been a frequent guest on The Daily Show, The Colbert Report, and Real Time with Bill Maher. In 2014, Tyson began hosting Cosmos: A Spacetime Odyssey on PBS, answering any questions you may have about space, earth and beyond!

This year, the best spots to soak in the setting sun are at 14th, 23rd, 34th. 42nd, 57th, and several streets adjacent to them. "The Empire State building and the Chrysler building render 34th street and 42nd streets especially striking vistas," said the scientist.

So what is the science behind Manhattanhenge? According to Tyson, "The sun does not set in the same place on the horizon each day. In fact, when people recite that the sun 'rises in the east and sets in the west,' that's only true for two days per year-the spring and fall equinoxes. In principle, any city with a rectangular street grid would have a 'henge' but not all grids extend to the horizon. Some hit forests or mountains. Others curve or bend, preventing the phenomenon from occurring. Manhattan's clear view to New Jersey-across the Hudson to the Palisades-makes an ideal setup for stunning sunsets."

What about some Instagramming tips? The astrophysicist also has some advice: "You want to be as far east on your cross street as possible, while retaining a view across Manhattan to the New Jersey horizon. This will frame your photo with a canyon of steel and glass buildings. Resist zooming into the sunset with your camera. Wider angle views that include the buildings that flank the sunset are what make the event special."

If you happen to miss tonight's, don't despair! You can see this spectacular sunset on Friday, July 11 8:24 P.M. EDT.
