Sinopsis
When Galileo pointed his telescope towards Saturn (circa 1610), he was not able to fully understand what was around the planet; in 1659 Christian Hygen published a drawing of the rings of Saturn and suggested there was thin, flat ring around the planet. He observed that the ring was inclined to the ecliptic and didn’t touch the planet. In 1675, Giovanni Domenic Cassini described that Saturn’s ring was composed of multiple smaller rings with gaps between them. In 1787, Pierre-Simon Laplace suggested that the rings were composed of a large number of solid ringlets. Research on the rings around Saturn continued and in 1859 James Clerk Maxwell demonstrated that the rings could not be solid or they would become unstable and break apart. When looked at from a distance, rings around Saturn appear thin with smooth surfaces; however close up images captured by various robotic space missions and additional data collected by sensors onboard several spacecraft visiting and flying-by Saturn show that there are number of
