CHICAGO (NewsNation Now) – One of the year’s best meteor showers, the Perseid, has begun dazzling stargazers across the U.S.

At its peak, the shower provides 50-100 meteors an hour for sky watchers to see, according to NASA.

When to watch it

The Perseid meteor shower is a yearly event viewable in the months of July and August. The Perseids were first visible beginning July 14, but will last through August 24. The peak is expected around August 11-13.

Clear skies are key to viewing the meteor shower. It is visible in some places as early as 10 p.m., but the nightly peak is between 2 a.m. and sunrise.

What is it?

The comet 109P/Swift-Turtle is responsible for the light show. The Perseid Meteor Shower is caused by the Earth traveling through debris and dust particles of the comet.

Those dust particles become the streaks of light visible in the sky when they collide with our atmosphere.

It’s called the Perseid meteor shower because the meteors appear to originate from the Perseus constellation — though this is not the source of the show.
