Explanation: The ongoing Perseid Meteor Shower should be at its strongest on August 12 and
13. The best time to watch will be between 2:00 AM and dawn on Monday morning (so plan on
setting your alarm tonight!) and then again on Tuesday. In dark, moonless, predawn skies you
may see dozens of meteors per hour. Grains of cosmic sand and gravel shed from Comet
Swift-Tuttle will streak across the sky as they vaporize |
