Perseid Meteor Shower 2008

This week the Perseid meteor shower arrived.  Meteor showers happen when the earth travels through debris left behind in the pathway of a comet.  Observers on Earth see a large number of "shooting stars".  There will be three more meteor showers before the end of 2008.  These are the Orionids (Oct. 21), the Leonids (Nov. 17) and the Geminids (Dec. 14). The Geminids promise to be the most dramatic of the upcoming showers.  Meteor showers are named for the constellations from which the meteors appear to originate.
