Pluto's the prettiest dwarf planet at the party in this new, brilliantly colored image recently released by NASA. Researchers used a process called principal component analysis to create the false-colored photo of Pluto, which highlights the subtle color differences among the different regions, NASA officials said in a statement. The original image was captured by the Ralph/MVIC color camera on NASA's New Horizons spacecraft as it passed within about 22,000 miles (35,000 kilometers) from Pluto during its flyby in July.
