Titan Sep 1, 2013A new study is revealing important details about the icy outer shell of Saturn's largest moon, Titan. Aug 6, 2013Titan's surface is dotted with lakes and seas... so where are all the waves? A new study may help to explain why bodies of water on Titan appear eerily smooth. Jun 20, 2013Scientists have found that a common antifreeze compound that might exist on Saturn's moon Titan can get trapped within ice-like cages. This discovery could influence our ideas about the evolution and development of life on Titan and other icy celestial bodies. May 18, 2013Scientists have published the first global topographic map of Saturn's moon Titan. The new map is a valuable tool for studying the moon, which is a prime target of interest for astrobiology in our solar system. Apr 18, 2013By studying the surface of Titan over several years, scientists have determined that the supply of the moon's hydrocarbon methane could be coming to an end. Apr 6, 2013Scientists previously thought that chemistry in Titan's atmosphere became more inert closer to the surface. Now, a new study suggests that complex organic chemistry that could lead to the building blocks of life extends lower in the moon's atmosphere than previously thought. Feb 6, 2013A new study using data from Cassini is helping scientists understand the behavior of smoggy aerosol layers in the atmospheres of Titan and Earth. Jan 20, 2013New observations from Cassini are helping scientists understand physical processes like stream erosion and drifting sand dunes on the surface of Saturn's moon, Titan. Jan 15, 2013A new paper explains the unexpected qualities of the surface of Titan as experienced by the Huygens probe when it landed on the moon eight years ago. In January of 2005, Huygens came to rest on Saturn's largest moon after bouncing, sliding and wobbling across Jan 10, 2013A new study shows that blocks of hydrocarbon ice may float on the surface of Titan's seas and lakes. Dec 26, 2012As 2012 draws to a close, Astrobiology Magazine highlights the year's top stories. At number 8, scientists revealed that Saturn's moon Titan likely harbors a layer of liquid water under its shell. The findings could have implications in the search for life in our solar Dec 15, 2012Cassini has spotted a river valley on Titan that stretches more than 400km from its 'headwaters' to a large sea. Dec 7, 2012A new analysis of data from Titan suggests that the moon's icy outer crust is twice as thick as scientists previously thought. Beneath this icy shell, which could be 200 kilometers thick, an ocean of liquid water is thought to exist. Dec 2, 2012Using data from Cassini, scientists have tied seasonal sunlight to an unexpected reversal in the circulation of Titan's atmosphere. Nov 2, 2012Cassini has captured images showing how Titan glows dimly in the dark. Light is emitted when charged particles bang into nitrogen molecules in the moon's dense atmosphere. The data is a glimpse into the processes behind the natural organic chemistry factory that exists on the

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
