Comets are.. bodies that formed at the very edge of the solar system, out beyond the orbit of Neptune, where Pluto is And they are the best preserved samples of the initial material that actually made the sun and earth and planets and even ourselves Since we've been in orbit, we've detected maybe four or five such storms This is by far the strongest that we've detected with Ca**ini And it's even stronger and there's more activity than the storms that were detected by the two Voyager spacecraft back in the early 1980s
