Alternating zones of rising and sinking gas in Jupiter's atmosphere create light and dark bands. In 1675 the Italian-born French astronomer Gian Domenico Cassini's discovery of a large gap—now known as the Cassini division—within the disk cast doubt on the possibility of a solid ring, and the French mathematician and scientist Pierre-Simon Laplace published a theory in 1789 that the rings were made up of many smaller components. This division is a 4,800-km-wide region between the A ring and B Ring.
