DDO Family Event - Perseid Meteor Shower Eve (WAITLIST)

The Perseids are the most reliably visible meteor shower at the most favorable part of the summer, the weekend of August 11th, at New Moon. If you have ever seen a shooting star, during a meteor shower you can expect to see many of them, appearing to radiate from the constellation Perseus in the northeastern sky. The meteors are created by particles of comet dust left in this part of Earth's orbit by a passing comet. Peter Millman, one of the first astronomers to work at the DDO, made the study of meteors like these the subject of his Harvard Ph.D. in 1932.
