Question 15

Pictures taken by the Cassini spacecraft show that the rings surrounding Saturn have dark and light bands. Until these pictures were taken, scientists on Earth did not know about this difference in color. Why was the Cassini spacecraft able to take pictures of the dark and light bands in Saturn's rings while they are not visible from Earth?

Accepted Answer

Telescopes on Earth are not powerful enough to see these differences at the great distance

Answer

The rings around Saturn are covered by thick, dark clouds made of toxic gases

Answer

Bright sunlight makes it difficult to see colors the farther it travels in the solar system

Answer

The differences between the light and dark bands are the result of minerals not found on Earth
