Comets are asteroid-like objects which are composed of ice, dust and rocky particles; that's why they are also called 'dirty snowballs'. The photograph is a time lapse shot so that more meteors are seen in the photograph than would be seen at one time (unlike the drawing above of what happened in 1833) What can be seen in the above photograph is the direction from which the meteors are coming as the Earth spins on its axis.
