The circle with the ring is a comet with a large
the comet moves, the coma loses dust and gas to the tail and then into
space to form a faint trail. The curved line
beneath the comet traces the trail of the coma from its beginning on

circle. On the left the comet is passing a planet, probably Earth, on
its way around the Sun and back again for final impact.
