The Perseids Meteor Shower will leave "celestial pollution"

In the last couple of days you may have wrapped up warm and gone outside to view the Perseids Meteor shower if you were lucky enough to have clear skies. During these last couple of nights, in some locations up to 60 were visible in an hour. These are caused by comet dust burning up and vaporizing in the atmosphere. These 'shooting stars' can be travelling up to speeds of 36 miles per second as it begins to burn up in the atmosphere. 

This Perseid Meteor shower are byproducts from the comet: Comet 109/Swift-Tuttle which passes earth every so often. 

Scientists at the 'Gemini Observatories' believe that they will leave behind a trail of what is known as 'celestial pollution' which is a mixture of gases. One of these being Sodium which collects in a layer in our atmosphere about 60 miles up from ground level. 

Scientists have found this to be true because they can use Sodium lasers to 'excite' the sodium so they can actually create artificial meteor showers anywhere in the world that they have these lasers and whenever the scientists want.
