Saturn's rings are dense clumps

In the US scientists had discover something new to the Saturn’s B ring. In photos and studies before shown that the ring was supposed to be very smooth and made up of many small particles. After further results and studies done on the ring the opposite of what the theory was wrong. When people or scientists look through the telescope the rings appear to be smooth and are far apart, but in fact they are made of clumps of particles.
These facts were presented by NASA along with the corporation of European and Italian Space agencies Cassini spacecraft also show that the ring’s particles are constantly colliding rather than going in an orderly form. From these results it surprises everyone. As the thought of Saturn’s rings being smooth and particles flowing in a direction constantly it is actually the opposite.
A scientist said “The rings are different from the picture we had in our minds,” said Larry Esposito of the University of Colorado at Boulder. Larry Esposito is an expert at studies using ultraviolet imaging. “We originally thought we would see a uniform cloud of particles. Instead we find particles clumped together with empty spaces in between” exclaimed Esposito. Other scientist also began to question that what the information they had gathered from before is wrong and in fact the ring might be 2 or 3 times denser that what they had thought.
Now the scientist have a new method of discovering how the rings are by the usage of light. "By studying the brightness of stars as the rings pass in front of them, we are able to map the ring structure in 3-D and learn more about the shape, spacing and orientation of clusters of particles," Colwell said in a statement.
From a journalist Lcarus said that the clumps are formed because of the gravitational attraction and the colliding of the rings particles. Also if the clumps were further from the planet Saturn, they might combine with each other or even form a moon. This didn’t happens as because the clumps of particles are so close to the gas giant/ planet, they would all be stretched apart from each other.
