Has a comet ever impacted Saturn’s rings? In this video we look at the impact of comet Shoemaker-Levy-9 on Jupiter’s rings in 1994. The impact by the comet on Jupiter created vertical ripples or corrugations that wind tighter with time. Therefore, it is possible to workout when an impact occurred by how tight the ripples are. This observed impact on Jupiter’s rings can then used be to determine that a comet hit Saturn’s rings in 1983, despite not being observed.
