Forensic Sleuthing Ties Ring Ripples to Impacts
With new spacecrafts up in space, scientists have discovered new evidence about the rings of the jovian planets. They have found that impacts can alter the rings of the planets and that they can use the rings to date back when the impacts occurred. This is very interesting because we can use it like "fingerprints" and discovered what happened over time.

If the rings are made up of dust particles and are not at all like the solid surface of a terrestrial planet, I wonder how they can find these impacts. It's not like it would leave an impact crater. And how can they determine the age from these rings? It's all very intriguing, scientists find new ways of collecting data all the time.
