Those awaiting the Cassini flyby success weren't dissatisfied. higher-resolution photographs showed very long, dark stripes of clean ground in close proximity to its south pole, which had been before long nicknamed “tiger stripes” (determine twelve.28).

Uranus’ rings are narrow and black, earning them Pretty much invisible from Earth. The nine primary rings ended up discovered in 1977 from observations fabricated from a star as Uranus handed before it. We contact this kind of passage of one astronomical item before Yet another an occultation

Every single of these rings shows a complicated composition that is certainly related to interactions concerning the ring particles as well as the much larger moons. on the other hand, the 4 ring systems are certainly different from Every other in mass, structure, and composition, as outlined in desk \(\PageIndex one \):
