The Perseid meteor shower, which gets its name from the constellation Perseus, is one of the most widely viewed meteor showers of the year.
With its most spectacular peak expected late Friday and Saturday, meteor-watchers are out and about, or even watching in the comfort of their homes online via NASA's live stream.
But this year's Perseid meteor shower is timed simultaneously with Earth's full moon, which is expected to hit maximum luminosity and reduce the number of visible meteors.
Viewers could maximize visibility by seeking dark country skies and going out between the hours after the moon sets and before twilight.
The Perseid meteors are a shower of dust and gas debris that comet 109P/Swift-Tuttle sheds off from the heat as it approaches the sun.
