Planetary impacts: Craters unchained
H. J. Melosh1
Ever since the appearance of those beautiful 'string of pearls' images, created by the break up of comet Shoemaker-Levy 9 in July 1994, planetary geologists have been excitedly looking for chains of impact craters caused by similar events. A good case can indeed be made that the lines of craters called 'catenae' on the Jovian satellites Ganymede and Callisto were created by the impact of other tidally split comets1.
