The mission team also put together global Ceres composition and topographic maps, the latter of which includes names for some features on the dwarf planet that were recently approved by the International Astronomical Union.
These names all have an agricultural theme. For instance, a 12-mile-wide (20 km) mountain near Ceres' north pole now bears the appellation Ysolo Mons, after a festival in Albania marking the first day of the eggplant harvest, NASA officials said.

The new Ceres maps are being discussed at the European Planetary Science Conference (EPSC) in Nantes, France, which runs from Sept. 27 through Oct. 2. At EPSC, Dawn team members are also talking about a puzzling observation made by the spacecraft - three bursts of energetic electrons from Ceres that may have been produced by interactions between the dwarf planet and solar radiation, NASA officials said.
"This is a very unexpected observation for which we are now testing hypotheses," Dawn principal investigator Chris Russell, of the University of California, Los Angeles, said in a statement. "Ceres continues to amaze, yet puzzle us as we examine our multitude of images, spectra and now energetic particle bursts."
