New Pluto Photo From NASA Horizons Shows Incredible Details

New Horizons has obtained impressive new images of Pluto and its large moon Charon that highlight their compositional diversity.

These are not actual color images of Pluto and Charon—they are shown here in exaggerated colors that make it easy to note the differences in surface material and features on each planetary body. (See video Below)

The images were obtained using three of the color filters of the “Ralph” instrument on July 13 at 3:38 am EDT. New Horizons has seven science instruments on board the spacecraft—including “Ralph” and “Alice”, whose names are a throwback to the “Honeymooners,” a popular 1950s sitcom.

“These images show that Pluto and Charon are truly complex worlds.  There’s a whole lot going on here,” said New Horizons co-investigator Will Grundy, Lowell Observatory, Flagstaff, Arizona.  “Our surface composition team is working as fast as we can to identify the substances in different regions on Pluto and unravel the processes that put them where they are.”

The color data helps scientists understand the molecular make-up of ices on the surfaces of Pluto and Charon, as well as the age of geologic features such as craters. They can also tell us about surface changes caused by space “weather,” such as radiation.

The new color images reveal that the “heart” of Pluto actually consists of two remarkably different-colored regions.  In the false-color image, the heart consists of a western lobe shaped like an ice cream cone that appears peach color in this image.  A mottled area on the right (east) side looks bluish.  A mid-latitude band appears in shades ranging from pale blue through red.  Even within the northern polar cap, in the upper part of the image, various shades of yellow-orange indicate subtle compositional differences. This image was obtained using three of the color filters of the Ralph instrument on July 13 at 3:38 am EDT and received on the ground on at 12:25 pm.
