A day to celebrate the sun

A few times each year, the rising and setting suns align with the east-west streets of Manhattan--commonly referred to as 'Manhattanhenge.' While the exact timing varies slightly from one year to the next, it usually occurs a few weeks before and after the summer and winter solstices. Tonight's sunset will find the full sun's golden rays streaming directly through Manhattan's major cross streets.

The name Manhattanhenge was created and popularized by NYC native and astrophysicist Neil deGrasse Tyson as an homage to Stonehenge. But Manhattan isn't the only place you can experience a 'henge' day--cities like Chicago and Toronto are also drawing crowds trying to capture a moment where the cosmos perfectly aligns with the modern.
