A dumb question here - are those false color photographs or is that the actual color of Uranus?
There may be rings on Uranus. But speak for yourself.
I don't know.
Unless someone is a failure at reading comprehension, there are no dumb questions, IMHO.
Here's the statement from Keck: "Using the near infrared camera (NIRC2) and adaptive optics on the Keck II telescope on May 28, the team took striking images of the nearly edge-on ring appearing as a bright line bisecting a dim Uranus, which appears dark in the infrared."
