The Rainbow Rings of Saturn

The Rainbow Rings of Saturn

This beautiful image spanning 10,000km of Saturn’s C (left) and B (right) rings was taken by Cassini. Cassini is the spacecraft that is carrying out missions around Saturn. This image was taken in the Ultraviolet wavelength when Cassini flew closest to the rings. The more blue the rings appear the more pure the water ice is that forms them. As the rings become redder the water ice contains more contaminants. 

We still don’t know how Saturn’s rings were formed. Theories suggest they may have formed at the same time as the planet or may have been formed by Saturn’s gravity capturing a passing object.
