Uranus from TitaniaThis painting, in acrylics, formed a double-page spread in Challenge of the Stars, Hardy's 1972 book with Sir Patrick Moore. At this time it was not known that Uranus has rings. | Rings of UranusUnlike Saturn's brilliant, icy girdle, the rings of Uranus (discovered by Voyager) are quite dark and widely spaced. Here we are among the rocky particles. The blue-green gas giant, with its retinue of satellites, rotates at almost a right-angle to the plane of its orbit. Uniquely, its poles can point towards the Sun. (Gouache) | Ice Cliffs of MirandaOne of the most spectacular discoveries of Voyager 2. Close to the south pole of Miranda, ice-cliffs rise up to 5km (3 miles) from the valley floor at an angle of 45-50 degrees. (Digital, from Futures.) |

Uranus is another gas giant, smaller than Jupiter and Saturn, and blue-green in colour. Its most unusual feature is that instead of spinning upright, like a top, it 'rolls' around its orbit like a ball on its side, its axis being tilted at 98 degrees (Earth's axial tilt is 23.5). Once thought to have 5 moons, the latest count was 27…
