Meteors are the blazing trails that smaller than one would expect dust leave while entering our atmosphere at huge velocities (from about 20 to 70 kilometers per second). A millimeter sized particle would produce a very bright meteor, probably not unlike the -8m one that left the trail pictured below. Sometimes these ionized gases remain visible for so long that high atmosphere winds distort them in funny ways:
The picture was taken in August 2008 during the maximum of the Perseid meteor shower from the top of the Omu Peak in the Romanian Carpathians.
