A four-panel image. The top two panels are diagrams of Uranus – spheres with gridlines going longitudinally and latitudinally. On the top left, the view from Hubble, the southern pole of the planet faces 3 o’clock. On the top right, the view from New Horizons, the southern pole faces 10 o’clock. The bottom left panel is Hubble’s actual view of Uranus – the planet is a light blue sphere, with a white circle covering the right half of the planet (the southern pole). The bottom right panel is the actual view of Uranus from New Horizons. The planet appears as a tiny whiteish dot.

Artist’s concept of Centaur 29P/Schwassmann-Wachmann 1 as seen from the side against a dark, mostly starless swath of space. The rocky, bilobed nucleus is toward the right and resembles the simplified shape of a peanut. The left side of the centaur is partially illuminated by the Sun, which is off-screen, revealing the nucleus’ light brown surface. Four jets of gas, depicted as translucent cones of white, emanate from various points on the Centaur’s surface and extend beyond the frame: two emanate upward from the top, one jet spews from the bottom and extends downward, and one jet emanates from the left side of the nucleus and extends toward the left. A label in the bottom left corner reads “Artist’s Concept.”
