"It is really surprising how closely Titan's surface resembles Earth's," says Rosaly Lopes, a planetary geologist at the Jet Propulsion Laboratory (JPL) in Pasadena, California, who is presenting the results on Friday, 7 August. "In fact, Titan looks more like the Earth than any other body in the Solar System, despite the huge differences in temperature and other environmental conditions." The joint NASA/ESA/ASI Cassini-Huygens mission has revealed details of Titan's geologically young...

The oil and gas that fuels our homes and cars started out as living organisms that died, were compressed, and heated under heavy layers of sediments in the Earth's crust. Scientists have debated for years whether some of these hydrocarbons could also have been created deeper in the Earth and formed without organic matter. Now for the first time, scientists have found that ethane and heavier hydrocarbons can be synthesized under the pressure-temperature conditions of the upper mantle...

HAMPTON, Va., April 2 /PRNewswire-USNewswire/ -- NASA scientist Michael Mumma and his team of researchers have discovered methane on Mars, indicating the planet is still alive -- either in a biologic or geologic sense. "The big question is, 'What is the origin of this methane now being released,'" Mumma says. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) While living systems produce more than 90 percent of Earth's atmospheric methane, other purely geological processes,...

WASHINGTON, Jan. 15 /PRNewswire-USNewswire/ -- A team of NASA and university scientists has achieved the first definitive detection of methane in the atmosphere of Mars. This discovery indicates the planet is either biologically or geologically active. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) The team found methane in the Martian atmosphere by carefully observing the planet throughout several Mars years with NASA's Infrared Telescope Facility and the W.M. Keck...

New research is challenging the recent finding that plants could be a major source of the atmosphere's methane levels. A study from 2006 suggested plants could account for almost half of the global production of the greenhouse gas, yet a UK-based team has found that under normal conditions, plants just convey methane from the soil to the air without actually producing it. The research suggests identifying sources of methane is key for climate control, as the gas is about 20 times more potent...

Chemists at the University of Liverpool have developed a way of converting methane gas into a powder form in order to make it more transportable.Scientists have developed a material made out of a mixture of silica and water which can soak up large quantities of methane molecules. The material looks and acts like a fine white powder which, if developed for industrial use, might be easily transported or used as a vehicle fuel.Methane is the principal component of natural gas and can be burnt in...

Tokyo, Aug. 23 (Jiji Press)--Japanese chemical makers are promoting the use of raw materials other than naphtha to combat soaring crude oil prices and ensure stable production. In departure from dependence on naphtha as a key raw material for chemical products, Sumitomo Chemical Co. will open a plant in Saudi Arabia to make raw materials of plastics from natural gas and ethane released during oil drilling. Once the plant starts operating by the end of March next year, Sumitomo Chemical's...

By Philip Haldiman, The Arizona Daily Star, Tucson Jul. 31--Our planet isn't the only heavenly body with liquid on its surface. Scientists from the University of Arizona and NASA on Wednesday announced at least one of the large, lakelike features on a moon of Saturn is wet. The moon, Titan, contains liquid hydrocarbons and ethane, scientists said. Besides Earth, this makes Titan the only known body in our solar system with liquid on its surface, NASA said in a press release. The...

Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...
