There are over 30 meteor showers annually. But few can compare to the spectacular Perseids. The "shooting stars" have been blazing through the sky at a rate of about a dozen an hour since mid-July and will continue until the end of August. But the best time to view them is when Earth passes through the area with the densest comet dust. That's when the meteors' pace increases to between 50 and 100 an hour. This year that will be during the pre-dawn hours of August 13.
