The region shown here is located between 13° and 51° north latitude and 182° and 228° east longitude. The image has been projected onto a globe of Ceres, which accounts for the small notch of black at upper right.
OpNav9 is the ninth and final set of Dawn images of Ceres taken primarily for navigation purposes.
Global stereo mapping of Pluto’s surface is now possible (requires red/blue glasses for viewing in 3-D), as images taken from multiple directions are downlinked from NASA’s New Horizons spacecraft. Stereo images will eventually provide an accurate topographic map of most of the hemisphere of Pluto seen by New Horizons, which will be key to understanding the dwarf planet’s geological history.
Scientists have long thought that Ceres may have a very weak, transient atmosphere, but mysteries lingered about its origin and why it’s not always present. Now, researchers suggest that this temporary atmosphere appears to be related to the behaviour of the Sun, rather than Ceres’ proximity to the Sun.
Sprawling across Pluto’s icy landscape is an unusual geological feature that resembles a giant spider. This enhanced colour image, obtained by NASA’s New Horizons spacecraft on 14 July 2015, consists of at least six extensional fractures (arrowed) converging to a point near the centre. Curiously, the spider’s “legs” expose red deposits below Pluto’s surface.
