Image: Pluto system 2005 discovery images

Description: Discovery images of Plutonian satellites P1 and P2. "The enhanced-color images of Pluto (the brightest object) and Charon (to the right of Pluto) were constructed by combining short exposure images taken in filters near 475 nanometers (blue) and 555 nanometers (green-yellow). The images of the new satellites were made from longer exposures taken in a single filter centered near 606 nanometers (yellow), so no color information is available for them."
