Fireball

Fireball

Fig. 12.18 . A great flash of light, called a fireball, is produced when a large meteoroid streaks through the atmosphere. It is often accompanied by sonic booms and rumbling noises. A camera-chopping shutter used for timing and velocity determinations produced spaces between the luminous segments of the fireballís trajectory. The faint curved lines in the background are star trails caused by the Earthís rotation during the three-hour exposure. (Courtesy of SAU.)
