Hubble just announced the discovery of a dark cloud in the atmosphere of Uranus, but as I looked at the press-release image, I realized that I was seeing Uranus from a slightly different angle compared to previous images. So I created the composite image above, using the various Hubble pictures of Uranus from 1994 through 2006. The Hubble crew did much the same thing with Saturn a few years ago, so it’s not an original idea. But it’s kinda kewl to see Uranus going through 14% of its orbit.
