Nearly two billion miles from earth the Voyager two space probe had more surprises for scientists today. Borges said back photographs revealing yet another moon and another ring around the planet Uranus but shares at the Jet Propulsion Laboratory in Pasadena. So far it is the moans around Uranus that are proving that best subjects for portraits. Ariel revealing countless craters on its surface Miranda with a V shaped ridge. On to Tony as scientists think the bright zigzag is something like frost indicating that some sort of material may be leaking up from the core of the moon and freezing. They're puzzled by unreal so bland in featureless it's hard to imagine how it evolved. And they're delighted with overrun where close ups indicate material on the floors of the craters more possible evidence of oozing from within. These are clearly not like the moon we are used to seeing. There are very different in general from the Earth's moon. In that these are icy objects largely icing. Scientists announced they'd spotted yet another new uranium known today bringing that total to fifteen. And they found a new rain although pointing out was an easy. You're telling me you can see it I can't. Among the other new reasons to rewrite science books as reports of an electoral blow high above the atmosphere of Uranus. A phenomenon similar to the northern lights or. Evidence that the planet's magnetic pole is a long way from its North Pole. And a reminder that the work of the spacecraft Voyager is not. Yet over. And in a certain sense the encounter is really just beginning for most the of the investigations and even though our closest approach was yesterday. I think we're all looking forward to the next cut several days. So we know Voyager is speeding away from Huron S it will continue to focus on that planet. Sending scientists here on earth a whole new world of data and pictures to analyze. And they do promise that the photographs will get better. Insurer ABC news at the Jet Propulsion Lab Pasadena.
