Berkeley -- A bound pair of icy comets similar to the dirty snowballs circling outside the orbit of Neptune has been found lurking in the shadow of Jupiter. Astronomers at the University of California, Berkeley, working with colleagues in France and at the Keck Telescope in Hawaii, have calculated the density of a known binary asteroid system that shares Jupiter's orbit, and concluded that Patroclus and its companion probably are composed mostly of water ice covered by a patina of dirt....

By Patricia Reaney LONDON (Reuters) - A distant object discovered in space last year which could be the 10th planet in our solar system is around a third bigger than Pluto, German astrophysicists said on Wednesday. They determined the diameter of the potential new planet, known as 2003 UB313, by measuring its thermal emission. "We actually measured the size of UB313 which was not known prior to these observations," Professor Frank Bertoldi, of the University of Bonn and the Max Planck...

By Irene Klotz CAPE CANAVERAL, Florida (Reuters) - The world's first mission to Pluto blasted into space on Thursday after its launch aboard an unmanned Atlas 5 rocket to begin a 9 1/2-year journey to the only unexplored planet in the solar system. "It's now our job to be good stewards of the spacecraft. and to learn to fly it in the real environment that it was built for," Alan Stern, the mission's lead scientist from the Southwest Research Institute in Boulder, Colorado, told a...

By Irene Klotz CAPE CANAVERAL, Florida (Reuters) - The world's first mission to Pluto blasted into space on Thursday on an unmanned Atlas 5 rocket to begin a 9 1/2-year journey to the only unexplored planet in the solar system. After two days of delays due to poor weather and a power outage, the 197-foot-tall (60-metre-tall) rocket, built by Lockheed Martin Corp., lifted off at 2 p.m. (1900 GMT) from Cape Canaveral Air Force Station. The launch team remained on edge until 45 minutes later...

CAPE CANAVERAL, Fla. -- An unmanned NASA spacecraft the size and shape of a concert piano hurtled toward Pluto on Thursday on a 3-billion-mile journey to the solar system's last unexplored planet - a voyage so long that some of the scientists who will be celebrating its arrival are still in junior high. The New Horizons spacecraft blasted off aboard an Atlas V rocket in a spectacular start to the $700 million mission. Though it is the fastest spacecraft ever launched, capable of reaching...

NASA -- These two bright debris disks of ice and dust appear to be the equivalent of our own solar system's Kuiper Belt, a ring of icy rocks outside the orbit of Neptune and the source of short-period comets. The disks encircle the types of stars around which there could be habitable zones and planets for life to develop. The disks seem to have a central area cleared of debris, perhaps by planets. The new disks, each about 60 light-years from Earth, bring to nine the number of dusty debris...

CAPE CANAVERAL, Florida (Reuters) - NASA canceled Wednesday's launch of the U.S. space agency's first probe to Pluto after the mission control headquarters in Maryland lost power, officials said. The launch of the piano-sized New Horizons spacecraft on a massive Atlas 5 rocket had been postponed from Tuesday due to high winds at the launch pad at Cape Canaveral Air Force Station. NASA officials said it was not immediately clear why mission control at Johns Hopkins University's...

NASA -- In the not-too-distant past, the planet Pluto was thought to be an odd bird in the outer reaches of the solar system because it has a moon, Charon, that was formed much like Earth's own moon was formed. But Pluto is getting a lot of company these days. Of the four largest objects in the Kuiper belt, three have one or more moons. "We're now beginning to realize that Pluto is one of a small family of similar objects, nearly all of which have moons in orbit around them," says Antonin...

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...

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...
