Pluto Once Had Rivers and Lakes of Liquid Nitrogen, New Horizons Data Suggests

Artist's conception of Pluto's surface, with the distant Sun and largest moon Charon in the sky. The surface is frozen now, but evidence suggests that rivers and lakes of liquid nitrogen once flowed here.

The Changing Bright Spots of Ceres: New Evidence for Geological Activity?

Artist’s conception based on a detailed map of the surface compiled from images taken from NASA’s Dawn spacecraft in orbit around the dwarf planet Ceres. New observations show that the bright spots change in brightness from day to night, suggesting that they change under the influence of sunlight as Ceres rotates, and may also indicate subsurface geological activity.
