Data from the NASA/ESA/ASI Cassini-Huygens mission are providing convincing evidence that Saturn's moon Phoebe was formed elsewhere in the Solar System, and was only later caught by the planet's gravitational pull. One way to unlock Phoebe's secrets is using Cassini's Visible and Infrared Mapping Spectrometer (VIMS), developed by a team of US (JPL), French and Italian (ASI) scientists and engineers. The science team is made by a large international group of US, Italian, French and German...

Flagstaff, AZ -- The planet Pluto turns 75 this month. Clyde Tombaugh discovered the ninth planet in the solar system on the afternoon of February 18, 1930 while he meticulously examined a pair of deep sky photographs at Lowell Observatory.  Tombaugh exposed the photographs on two nights in late January using the Observatory's 13-inch Abbott Lawrence Lowell Telescope. Then, as part of the carefully planned and executed planet search, Tombaugh "blinked" the two exposures using a machine...

The evolution of Kuiper Belt objects, Pluto and its lone moon Charon may have something in common with Earth and our single Moon: a giant impact in the distant past. Astrobiology Magazine -- The evolution of Kuiper Belt objects, Pluto and its lone moon Charon may have something in common with Earth and our single Moon: a giant impact in the distant past. Dr. Robin Canup, assistant director of Southwest Research Institute's (SwRI) Department of Space Studies, argues for such an origin for the...

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. Astrobiology Magazine -- Number six on the countdown of 2004 highlights was detection of planetoids beyond...

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. Astrobiology Magazine -- A planetoid beyond Pluto was discovered using the Hubble Space Telescope in October 2002, and given the name, Quaoar. Like...

GITR -- In 30 years, a nuclear-powered space exploration mission to Neptune and its moons may begin to reveal some of our solar system's most elusive secrets about the formation of its planets -- and recently discovered ones that developed around other stars. This vision of the future is the focus of a 12-month planning study conducted by a diverse team of experts led by Boeing Satellite Systems and funded by NASA. It is one of 15 "Vision Mission" studies intended to develop concepts in the...

Close encounter may explain some objects beyond Neptune Cambridge, MA -- A hit TV program like "Antiques Roadshow" lures viewers with its universal appeal. Who wouldn't want to find secret riches in their attic or basement? But rare paintings and heirloom jewelry aren't the only valuable items waiting to be discovered. Cosmic treasures also lay hidden in the vast realm of outer space. Among the most highly prized of those treasures are planets that formed around other stars. Astronomers have...

Planet -- A planet is a body of considerable mass that orbits a star and that doesn't produce energy through nuclear fusion. Until recently, only nine were known (all of them in our own Solar system). As of the end of 2002 over 100 are known, with all of the new discoveries being extrasolar planets. Astronomers often call asteroids minor planets, and call the larger planetary bodies (those which are commonly called planets) major planets. Planets within the solar system can be...

Asteroid -- An asteroid, also called a minor planet or planetoid, is a member of a group of small, planet-like bodies that are part of our solar system. They are believed to be remnants of the interstellar clouds, nebula, that were not incorporated into planets during the formation of the solar system. The largest asteroid in the inner solar system is Ceres with a diameter of 1003 km. It also was the first to be discovered, by Giuseppe Piazzi on January 1, 1801. Nowadays, over 9000...

Solar System

The Solar System refers to the area in space that is dominated by our own Sun. It is comprised of the Sun and its associated astronomical objects that are held in its gravitational orbit. The Solar System was formed as a result of the collapse of a giant molecular cloud approximately 4.6 billion years ago. The mass of this system is located almost entirely in the Sun. Apart from the Sun, a high percentage of the remainder of the system’s mass is located in the eight solitary planets that...

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...

Oort Cloud -- The Oort cloud is a postulated cloud of comets situated about 50,000 to 100,000 AU from the sun. Although no direct observations have been made of such a cloud, it is believed to be the source of most or all comets entering the inner solar system (some short-period comets may come from the Kuiper belt), based on observations of the orbits of comets. The Oort cloud was proposed in 1950 by Dutch astronomer Jan Oort to explain an apparent contradiction: comets are destroyed...
