KINGS PARK - Long Islanders looking toward the sky tonight are expected to be treated to the year's best meteor shower.

The Perseids meteor shower should be visible after 11 p.m. and last into the early morning hours.

Lorraine Vernola, an astronomer with the Suffolk County Vanderbilt Museum and Planetarium, says a meteor shower is "debris left over from the comet Swift-Tuttle."

She says the debris is about the size of a grain of sand, and leaves a streak of light as it burns up while traveling through the Earth's atmosphere.

Some ideal locations to watch the shower include Jones Beach, Montauk Point and Sunken Meadow state parks.
