COVER A montage of images of Jupiter and its volcanic moon Io, taken from the spacecraft New Horizons. On Jupiter, high-altitude clouds are shown in blue and deeper clouds in red. The bluish-white oval is the Great Red Spot. Just visible in the Io image is an ongoing volcanic eruption on its nightside, in which incandescent lava glows red beneath a high volcanic plume lit by sunlight. See the special section beginning on page 215. Images: Jupiter, infrared color composite from the Linear Etalon Imaging Spectral Array (LEISA) reprojected onto a crescent to compensate for rotational distortion; Io, approximate true-color composite from the Long-Range Reconnaissance Imager (LORRI) with color information from the Multispectral Visible Imaging Camera (MVIC); NASA/APL/SwRI/GSFC
