The Perseid meteor shower is underway…

Earth is entering a stream of debris from giant comet 109P/Swift-Tuttle, parent of the annual Perseid meteor shower.

Although the shower is not expected to peak until next weekend, NASA all-sky cameras are already detecting dozens of Perseid fireballs every night over the USA.

This early activity may be a good omen for the nights ahead, especially Aug. 11th-13th when Earth is expected to pass through the densest part of the comet’s debris zone.
