Scientists have discovered that a dwarf planet at the edge of the solar system, dubbed 2007 OR10, is an icy world with about half its surface covered in water ice that once flowed from ancient, slush-producing volcanoes.

Counting down the top ten astrobiology stories for 2004 highlights the accomplishments of those exploring Mars, Saturn, comets, and planets beyond Pluto. Number six in this countdown was the discovery of potential heat sources for ice beyond Pluto, an important finding if water is considered the key ingredient to understanding biological probabilities elsewhere in the solar system.

In October 2002, the Hubble Space Telescope first spotted an icy planetoid beyond Pluto. Named after an American Indian god, Quaoar, the planetoid should be far colder based on its distance from the sun than it appears to be. One reason for its temperature may be internal heating from a radioactive core, or alternatively volcanoes and impacts.

Quaoar -- Quaoar ("kwah-oh-ahr", /kwA o Ar/) is a Trans-Neptunian object circling the Sun in the Kuiper belt, discovered in 2002 by astronomers Chad Trujillo and Mike Brown at the California Institute of Technology in Pasadena, California. Quaoar is estimated to have a diameter of about 1,280 kilometres, which would make it the largest Solar System object discovered since Pluto and, indeed, the largest known minor planet. Larger than all the asteroids put together, it is about one...

Kuiper Belt -- The Kuiper belt is an area of the solar system extending outwards from the orbit of Neptune (at 30 AU) to 50 AU. The largest of the objects in the Kuiper belt are the planet Pluto and its moon Charon. A new Kuiper belt object, currently called 2001 KX76, has been found that is about the size of Charon, and larger than Ceres. Another such object, Quaoar, discovered in 2002, is half the size of Pluto. Other known Kuiper belt objects are progressively smaller. The exact...

Planet Pluto -- Pluto is the ninth and smallest planet of our solar system. It was discovered by the astronomer Clyde Tombaugh at the Lowell Observatory in Arizona on February 18, 1930 (although the body was first photographed on March 19, 1915). Tombaugh was searching for a "Planet X" to explain the orbit of Neptune; further analysis, with seven decades more data about Neptune's position, has resolved the perceived anomaly without need for an additional gravitational pull on Neptune....
