Pluto and Charon Seen by New Horizons
Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute
New Horizons LOng Range Reconnaissance Imager (LORRI) composite image showing the detection of Pluto’s largest moon, Charon, cleanly separated from Pluto itself. The frame on the left is an average of six different LORRI images, each taken with an exposure time of 0.1 second. The frame to the right is the same composite image but with Pluto and Charon circled; Pluto is the brighter object near the center and Charon is the fainter object near its 11 o’clock position. Images released July 10, 2013. [Read the Full Story]

From left to right is the before, during and after of the occultation of C313.2 by Charon on July 11. The brightest object in the center of the frame is Pluto. Below and to the left is the merged light from Charon and the background star. During the occultation (center image), only Charon is visible. The images are from the 6.5-meter Clay telescope at Las Campanas Observatory in Chile.

Pluto Unveiled
Credit: NASA, ESA, and M. Buie (Southwest Research Institute)
This is the most detailed view to date of the entire surface of the dwarf planet Pluto, as constructed from multiple NASA Hubble Space Telescope photographs taken from 2002 to 2003. The center disk (180 degrees) has a mysterious bright spot that is unusually rich in carbon monoxide frost. The image was released in February 2010. See the dwarf planet turn in a video based on these images.

The Pluto System As Seen from Nix or Hydra
Credit: NASA, ESA and G. Bacon (STScI).
The artist's concept gives a view of the Pluto system from the surface of Nix or Hydra, two of its moons discovered in 2005. Nix and Hydra are two to three times farther from Pluto than its large moon, Charon (to the right of Pluto), which was discovered in 1978.

An artist's conception of Charon with Pluto in the background. The plumes and brighter spots depicted on Charon are thought to due to ammonia-laced water erupting from deep beneath the moon's surface.

Artist's Impression of Dwarf Planet Eris
Credit: ESO/L. Calçada
This artist's impression shows the distant dwarf planet Eris. New observations have shown that Eris is smaller than previously thought and almost exactly the same size as Pluto. Eris is extremely reflective and its surface is probably covered in frost formed from the frozen remains of its atmosphere.

Occultation of Dwarf Planet Eris in November 2010
Credit: ESO/L. Calçada
This diagram shows the path of a faint star during the occultation of the dwarf planet Eris in November 2010. Two sites in South America saw the faint star briefly disappear as its light was blocked by Eris and another recorded no change in brightness. Studies of where the event was seen, and for how long, have allowed astronomers to measure the size of Eris accurately for the first time. Surprisingly, they find it to be almost exactly the same size as Pluto and that it has a very reflective surface.

Artist’s Impression of the Dwarf Planet Eris and Moon Dysnomia
Credit: ESO/L. Calçada
This artist's impression shows the distant dwarf planet Eris in the distance with its moon Dysmonia in the foreground. New observations have shown that Eris is smaller than previously thought and almost exactly the same size as Pluto. Eris is extremely reflective and its surface is probably covered in frost formed from the frozen remains of its atmosphere. Dysnomia appears to be a darker and less reflective body.

Dwarf Planet Eris' Shadow Path During November 2010 Occultation

This artist’s impression shows the shadow of the dwarf planet Eris as it was crossing the Earth during the occultation during November 2010. The regions along the path saw a faint star briefly disappear as its light was blocked by Eris. Studies of where the event was seen, and for how long, have allowed astronomers to measure the size of Eris accurately for the first time. Surprisingly, they find it to be almost exactly the same size as Pluto and that it has a very reflective surface.

This artist's impression shows the distant dwarf planet Eris. New observations have shown that Eris is smaller than previously thought and almost exactly the same size as Pluto. Eris is extremely reflective and its surface is probably covered in frost formed from the frozen remains of its atmosphere. The distant Sun appears to the upper right and both Eris and its moon Dysnomia (center) appear as crescents.
