Saturn's new discovered ring

NASA scientists have just observed an almost invisible ring around Saturn planet. The orbit of the ring is tilted by 27 degrees with respect to the main ring plane. Saturn's supersized ring starts at 6 million km from the planet and extends outward some other 12 million km. Its diameter equals 300 Saturns lined up and the occupied volume can handle 1 billion Earths.
The difficulty in the observation was due to the very low density of the ice an dust particles the ring is made up and the small sunlight received by Saturn which makes the reflection tiny.
