Titan Aug 5, 2004During the July 2, 2004 flyby of Titan, Cassini was able to look at this largest of Saturn's moon using different filters to give a view of the dividing lines between night and day, atmosphere and surface. Jul 30, 2004Cassini's camera captured a good view of the upper and lower atmosphere on Saturn's moon Titan. The moon has a thicker atmosphere than Earth's. Jul 4, 2004Cassini's visible and infrared mapping spectrometer pierced the smog that enshrouds Titan. Dark regions of relatively pure water ice were found mixed with lighter regions of simple hydrocarbons. Jul 3, 2004New images and spectroscopic data of the surface of Titan, Saturn's largest moon, have puzzled NASA scientists. Light areas once thought to be pure water ice are instead regions likely contaminated by organic materials. Jul 2, 2004Robotic missions have returned images from the surfaces of Venus, Mars and even asteroids, but when the Huygens probe tries to capture topography from Saturn's largest moon, Titan, the landscape may rival science fiction in the descriptions of how exotic another world might look. Jun 30, 2004Gauging wind speeds on Titan depends on where in the thick atmosphere the probe tries to measure changes in direction or magnitude. What scientists see today is just the top, smoggy layer, but new benchmarks may arrive from an unlikely and smog-free place: the Jun 30, 2004The orange-brown color of Saturn's moon, Titan, shows in true hues with the latest Cassini closeup. Jun 29, 2004The Cassini spacecraft has sent back images three times better than previous best views of the intriguing moon, Titan. Using a near-infrared polarizing filter, much of Titan's smog can be penetrated to look at the patchy surface. May 23, 2004Titan, Saturn's hydrocarbon-rich moon, appears to host oil lakes and the raw materials for making organics. Those organics may serve as precursors to plastics, or possibly simple biomolecules. May 7, 2004As the Cassini probe closes in on Saturn's fascinating moon, Titan, its dark and bright spots already appear but their mysterious origins will have to await a July 2nd unveiling. Apr 18, 2004New ground-based observations of Titan have identified three bright atmospheric regions. These spots may help explain what this oil-rich moon may offer the latest probe in just a few months when Cassini begins to orbit around Saturn. Apr 6, 2004The Chandra X-ray Telescope caught a rare event, the passage of Saturn's biochemically rich moon, Titan, in front of the x-ray bright Crab nebula. Astronomers seized the moment to make the first x-ray measurements of Titan's thick, smoggy atmosphere. Apr 1, 2004Observations taken atop the Chilean mountains reveal strange atmospheric patches on Saturn's largest moon, Titan. Although seen from the Hubble space telescope, the thick smog on Titan has proven a difficult photographic opportunity. Mar 31, 2004Saturn's moon, Titan, is thought to harbor lakes of hydrocarbons. By modelling these waves using Titan's gravity, scientists predict seven times higher crests spaced widely apart compared to similar inputs on Earth. Mar 1, 2004Saturn's largest moon, Titan, has one of the most promising chemical laboratories for producing complex organic molecules. Experiments conducted in preparation for this summer's mission to probe Titan's astmosphere have tried to simulate its cold, prebiotic soup.

Prevela i uredila: Ljubica Šaran Matrix World 200 milja visok vrtložni oblak nalik stupu je provrio iz magličaste atmosfere Saturnovog mjeseca Titana. NASA-ini znanstvenici su zbunjeni snimkama letjelice Cassini koja je na Zemlju poslala fotografije vrtloga na Titanovom južnom polu. Ovo otkriće bi moglo donijeti nove podatke o misterioznoj atmosferi Titana gdje jedno godišnje doba traje sedam godina i na čijem se tlu stvaraju smrznute dine kemikalija koje se polako kližu diljem površine planete. Jedan od članova NASA-inog tima je izjavio kako formacija jako nalikuje na oblake koji se mogu vidjeti nad oceanima naše planete. Tony Del Genio je rekao: „No za razliku od oblaka na Zemlji gdje se oni nalaze neposredno iznad površine, ovaj oblak na Titanu se nalazi na vrlo velikim visinama, možda je nastao zbog procesa hlađenja na Titanu zbog činjenice da počinje zima na njegovom južnom polu. No to se ipak dogodilo prerano da bi bili sigurni.“ Slike koju je snimila NASA-ina letjelica Cassini pokazuju koncentraciju visinske maglice i vrtlog koji se formira na južnom polu Titana što je znak da se mijenjaju godišnja doba na najvećem Saturnovom mjesecu. Nedavna gravitacijska mjerenja su pokazala da Titan vjerojatno ima oceane ispod površine – oceane koji su napravljeni od vode i koji imaju dubinu od nekoliko stotina kilometara. Čini se da ti oceani prekrivaju cijelu površinu Titana no ispod naslaga leda koje su debele 100 kilometara. Kategorije:SVEMIR KROZ TELESKOP
