Manhattanhenge, a portmanteau of “Manhattan” and “Stonehenge,” is a twice-a-year solar event when the sunset lines up directly with the city’s grid, casting golden rays down city streets. Several of the stones in Stonehenge, the prehistoric monument in Wiltshire, England, experience perfect alignment with the sun during the summer and winter solstices, which is why the event takes its name from the rock formation.

If you miss it today, don’t fret: it happens again in July during MLB’s All-Star Break.
And the next day after each “half-sun” event, you can still see the “full-sun” version. Anybody in NYC?
