Perseids are often fast, bright meteors and frequently leave long, persistent visual trains, said Steven Emert of the Minnesota Astronomical Society.

Swift-Tuttle orbits the sun every 130 years. The light streaks are generated as air friction vaporizes the dust grains. What you see blazing across the sky is mainly the ionized air.
