8 METRO Monday, December 21, 2009 D Titanic task for Saturn study A PROPOSAL to try to put a boat down on a sea of Saturns moon Titan is about to be submitted to Nasa. The scientific team behind the idea is targeting a body of liquid methane on Saturns largest moon. It would be the first exploration of a planetary sea beyond Earth and is hoped to explain Titans methane-ologic system, which would help scientists study shared climate processes under very different conditions. People pose for photographs inside a snow globe shaped Christmas decoration outside a shopping mall in Taipei, Taiwan ONE MOMENT IN TIME Head cameras to aid police arrests POLICE in California are to test head-mounted cameras to record interactions with the public at a cost of $4million (2.8m) per department. The move comes following criticism from citizens groups in San Jos over the use of excessive force during arrests. The cameras, the size of a mobile phone earpiece and attached by a headband above the ear, will be turned on anytime an officer speaks to anybody, and are downloaded after every shift. But they are costly at $1,700 (1,100), plus a $99 (70) per officer monthly fee, each. Avatar-like moons may be possible HABITABLE alien moons like the one depicted in the movie Avatar may become science fact within the next few years, a leading astronomer has claimed. In the 3D film, a race of 3m (10ft) blue-skinned giants inhabit an Earth- like moon called Pandora.Their world orbits a gas giant planet similar to Ju- piter which cannot support life. US astronomer and planet-hunter Lisa Kaltenegger, from the Harvard- Smithsonian Center for Astrophysics in Cambridge, Massachusetts, be- lieves there is every chance a real-life version of Pandora exists and will soon be found. She has conducted research showing a planned new space telescope will be able to identify nearby exomoons and discover if they are habitable. The American space agency Nasas James Webb Space Telescope is due to be launched in 2014. Dr Kaltenegger said: If Pandora ex- isted, we potentially could detect it and study its atmosphere in the next decade. Astronomers have already spotted hundreds of Jupiter-sized gas giants orbiting stars, but so far, none have conditions suitable for Earth-type life. BY JOHN von RADOWITZ Avatar: Are we really alone? Eiffel is at top of landmarks tower THE Eiffel Tower has been voted top of a famous landmarks poll. St Peters in Rome was second, with the Taj Mahal in India third and San Franciscos Golden Gate Bridge fourth. The poll by Hotels.com also showed the Spanish were most keen to travel to a city specifically to see a landmark. New Yorks Empire State Building and Statue Of Liberty, Sydneys Opera House, Barcelonas Gaudi-designed Sagrada Familia church, the Acropolis in Athens and Christ The Redeemer in Rio also made the top ten.
