Outer solar system Jan 19, 2006The New Horizons mission launched from Cape Canaveral, Florida at 2 p.m. Eastern time this afternoon. The spacecraft is now headed to the planet Pluto, speeding from Earth at 8 miles per second. Because Pluto is so far away, it will take New Jan 18, 2006In 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 Jan 8, 2006Being in the right place at the right time gave a group of Massachusetts research astronomers a unique opportunity to study Pluto's largest moon Charon. The resulting measurements, to unprecedented accuracy, of Charon's size and possible atmosphere provide insight into the way this distant world Jan 6, 2006Mercury is boiling. Mars is freezing. The Earth is just right. When it comes to the temperatures of the planets, it makes sense that they should get colder the farther away they are from the Sun. But then there is Pluto. It has been suspected Dec 30, 2005The University of Colorado at Boulder's long heritage with NASA planetary missions will continue Jan. 17 with the launch of a student space dust instrument on the New Horizons Mission to Pluto from Florida's Kennedy Space Center. Dec 25, 2005NASA's Hubble Space Telescope photographed a new pair of rings around Uranus and two new, small moons orbiting the planet. The largest ring is twice the diameter of the planet's previously known rings. The rings are so far from the planet, they are being called Dec 20, 2005The New Horizons spacecraft, scheduled for launch in mid-January, will investigate the far-off planet Pluto and its icy moons. This will be the first spacecraft to study the Pluto system, as well as the mysterious outer region of our solar system Nov 1, 2005A team of astronomers at Southwest Research Institute (SwRI) and other institutions has discovered that Pluto has two previously unseen moons. Ground-based observers discovered Pluto's only previously known moon, Charon, in 1978. The planet itself was discovered in 1930. Oct 7, 2005The newly discovered 10th planet, 2003 UB313, is looking more and more like one of the solar system's major players. It has the heft of a real planet (latest estimates put it at about 20 percent larger than Pluto), a catchy code name (Xena, after Sep 10, 2005When planetary scientists announced on July 29 that they had discovered a new planet larger than Pluto, the news overshadowed the two other objects the group had also found. Jul 31, 2005A planet larger than Pluto has been discovered in the outlying regions of the solar system. The planet is a typical member of the Kuiper belt, but its sheer size in relation to the nine planets already known means that it can only be classified Jul 23, 2005In a feat of astronomical and terrestrial alignment, a group of scientists from MIT and Williams College recently succeeded in observing distant Pluto's tiny moon, Charon, hide a star. Such an event had been seen only once before, by a single telescope 25 years May 24, 2005NASA's Voyager 1 spacecraft has entered the solar system's final frontier. It is entering a vast, turbulent expanse, where the sun's influence ends and the solar wind crashes into the thin gas between stars. Feb 1, 2005The 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. Dec 30, 2004Counting 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

ASTRONOMSKO OTKRIĆE Možda nije planet, ali vrvi mjesecima: Uz pomoć teleskopa Hubble pronađen peti Plutonov mjesec AP Photo / NASA Otkrili su ga znanstvenici pod vodstvom Marka Showaltera iz američkog instituta SETI u Kaliforniji WASHINGTON - Znanstvenici su svemirskim teleskopom Hubbleom otkrili peti mjesec koji kruži oko patuljastog planeta Plutona, javljaju svjetski mediji. Novi mjesec, vidljiv u obliku svjetlosne mrlje na fotogtafijama Hubblea, po procjenama je nepravilna oblika i dijametra između 10 i 25 kilometara. Otkrili su ga znanstvenici pod vodstvom Marka Showaltera iz američkog instituta SETI u Kaliforniji. Mjesec, zasad poznat samo kao P5, mogao bi pomoći u otkrivanju načina na koji se sustav oko Plutona stvorio i razvio. Po jednoj teoriji, mjeseci su ostaci sudara Plutona i drugog velikog ledenog tijela prije nekoliko milijardi godina. Plutonov najveći mjesec, Haron, otkriven je 1978. godine. Prije šest godina otkrivena su još dva manja mjeseca, Nikta i Hidra, a prošle godine mjesec koji još nije dobio mitološko ime i naziva se samo P4. Pluton je godine otkrio Amerikanac Clyde Tombaugh 1930. godine i smatrao se devetim planetom Sunčeva sustava sve do degradacije u patuljasti planet 2006. New Horizons, bespilotna svemirska letjelica NASA-e, na putu je prema Plutonu i trebala bi pokraj njega proletjeti 2015. godine. Na Zemlju bi trebala poslati prve detaljne snimke Plutonova sustava koji je toliko malen i dalek da čak i teleskop Hubble jedva vidi najveće strukture na njegovoj površini. Više o...
