Lee Rannals for redOrbit.com - Your Universe Online Scientists announced on Wednesday they have discovered the smallest moon yet, orbiting around the dwarf planet Pluto. The discovery was made by a team of scientists who used the Hubble Space Telescope to scout out Pluto's neighborhood ahead of a NASA spacecraft that is scheduled to arrive in 2015. The new moon, known as P5 currently, appeared as a small fleck in the Hubble images, and scientists believe it is about 6 to 15 miles...

Fifth Moon Orbiting Pluto Discovered By Hubble
2012-07-11 20:53:03

A team of astronomers using NASA´s Hubble Space Telescope is reporting the discovery of another moon orbiting the icy dwarf planet Pluto. The moon is estimated to be irregular in shape and 6 to 15 miles across. It is in a 58,000-mile-diameter circular orbit around Pluto that is assumed to be co-planar with the other satellites in the system. “The moons form a series of neatly nested orbits, a bit like Russian dolls,” said team lead Mark Showalter of the SETI Institute...

New Evidence Found For Complex Molecules On Pluto's Surface
2011-12-21 04:33:06

The new and highly sensitive Cosmic Origins Spectrograph aboard the Hubble Space Telescope has discovered a strong ultraviolet-wavelength absorber on Pluto's surface, providing new evidence that points to the possibility of complex hydrocarbon and/or nitrile molecules lying on the surface, according to a paper recently published in the Astronomical Journal by researchers from Southwest Research Institute and Nebraska Wesleyan University. Such chemical species can be produced by the...

NASA´s New Horizons mission reached a special milestone Friday, Dec. 2, 2011, on its way to reconnoiter the Pluto system, coming closer to Pluto than any other spacecraft. It´s taken New Horizons 2,143 days of high-speed flight — covering more than a million kilometers per day for nearly six years–to break the closest-approach mark of 1.58 billion kilometers set by NASA´s Voyager 1 in January 1986. “What a cool milestone!” says New Horizons...

Image 1 - Astronomers Size-Up Dwarf Planet Eris

[ Watch the Video ] The European Southern Observatory (ESO) announced on Wednesday that astronomers have accurately measured the diameter of the dwarf planet Eris for the first time. The astronomers believe that the dwarf planet is an almost perfect twin of Pluto in terms of size.  The planet, according to ESO, appears to have a reflective surface, which suggests it is uniformly covered in a thin layer of ice. Astronomers made observations as Eris passed in front of a faint...

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...

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 Charon -- Charon is the only known satellite of Pluto. Charon was discovered by astronomer James Christy in 1978 using photographic plates which showed a bulge moving around Pluto. Christy named it after the Greek mythological figure Charon but pronounced it differently. The "ch" at the beginning of the moon's name is soft so it sounds like "Sharon," after the astronomer's wife Charlene, nicknamed Char, which both have soft ch sounds. The mythological figure's name is...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
