Philly will Experience its Deepest Solar Eclipse in 40 Years — Here’s How to View It

Watching a total solar eclipse is something you never forget.

Philadelphians won’t quite get that chance this time around, but on April 8 residents will be able to experience the deepest eclipse the city’s seen in four decades.

A total solar eclipse — when the sun, moon and Earth align and the moon’s shadow blocks the sun’s light — happens about once every 18 months somewhere in the world.
