	Titan may have methane volcano \| www.azstarnet.com ®
		Cryovolcanoes are vents that erupt ice, water or cold, volatile gases, with some gas-driven solid chunks, instead of hot lava.
		The cryovolcano, reported in this week's issue of the journal Nature, was spotted during a flyby of Titan from 750 miles away by the spaceship Cassini last fall.
		It stands to create a rift between Robert Brown, the local scientist who is one of 26 co-authors on the paper, and fellow UA scientists who helped engineer the Huygens probe, which hitched aboard Cassini and landed on Titan's surface in January.

	Cracks Or Cryovolcanoes? Surface Geology Creates Clouds On Titan
		This is the conclusion of planetary astronomer Henry G. Roe, a postdoctoral researcher, and Michael E. Brown, professor of planetary astronomy at the California Institute of Technology.
		It may seep out of transient cracks on the surface, or bubble out during the eruption of icy cryovolcanoes.
		Although no such features have yet been observed on the moon, Roe and his colleagues believe they may be common.

	Saturn's Titan like Earth, yet enigmatically different / Surface, atmosphere composed of exotic materials, Cassini finds
		Perhaps, the scientists said, Titan's surface is covered by a thin crust of ice lying over a soft, spongy layer that has long since absorbed the impact of earlier craters.
		Or it may be that unknown organic ices and volatile chemicals erupting from undetected cryovolcanoes have buried all evidence of hundreds or thousands of other craters.
		They also were surprised to find no very small craters, because the entire solar system with all its planets and planetary moons must have been under continued heavy bombardment for millions of years as the system was forming some 4.5 billion years ago.

		These might be incorporated into the crust through various mechanisms (anchor ice, ice ploughing, density flotation, cryovolcanism, and tidal and current action).
		Extant or extinct habitats may be exposed in outcrops or slumps in tectonic features, including ridges and troughs formed by tidal flexing, chaotic terrains with displaced ice blocks kms across embedded in a matrix of disturbed ice, bands of newer ice, cryovolcanoes, domes and pits, and fault scarps.
		Impact craters pierce the crust, exposing older ice in crater walls, central peaks, overturned ice, and ejecta.

		One idea is that the dimples resulted from internal explosions, another that they were produced by melting and collapse of the icy surface.
		The most interesting and totally unexpected features on Triton are its cryovolcanoes (ice volcanoes).
		One of Voyager's images shows an actual plume rising 8 km above the surface and extending 140 km downwind.

	Titan Weather: Storm Trackers :: Astrobiology Magazine ::
		The discovery was made using the Gemini North and Keck 2 observatories, which have adaptive optics systems capable of resolving Saturn's largest moon with great detail.
		These storms could be created by surface activities, like cryovolcanoes which could spew an icy mix of chemicals into the atmosphere.
		It could also be caused by seasonal temperature changes, like the weather here on Earth.

		Geological sketches of the "snail's shell" structure on Titan
		On 14 January 2005, having been transported by Cassini to the Saturn system, the European probe Huygens landed on Titan’s icy outer shell with the aid of a parachute and sent back some spectacular images of a landscape in motion, covered with methane rivers and swamps.
		At the landing site, situated about 500 km from the cryovolcano discovered by Cassini, ice debris can be seen in a landscape which can be interpreted as a flooded plain.

	Cassini Enceladus Flyby (how now, brownpau?) (Site not responding. Last check: 2007-10-26)
		This would indicate recent geologic activity: tectonics caused by gravitational tidal forces from Saturn, wiping out impact craters and forming cracks and bumps.
		Enceladus also has a tenuous atmosphere, which might be caused by cryovolcanoes spewing material from underground, covering the moon's surface with icy particles, and replenishing Saturn's E ring with new material.
		This is all theory, of course: no volcanic plumes have been spotted on Cassini yet.

	Glossary (Site not responding. Last check: 2007-10-26)
		Cryovolcanic: Of or pertaining to cryovolcanoes, which are, literally, icy volcanoes.
		Cryovolcanoes form on icy moons, such as Enceladus, and possibly on other low temperature astronomical objects.
		Rather than molten rock, these volcanoes erupt volatiles such as water, ammonia, or methane compounds.

		Owen said, and there is some suggestion of cryovolcanoes, volcaniclike vents that spew forth ice instead of lava.
		He said features detected by the Cassini spacecraft, orbiting Titan, show channels resembling volcanic features on Earth, but they may have been carved by creeping ice, not molten rock.

	Software for Analyzing Scientific Data Aboard a Spacecraft
		In tests thus far, the program recognized 80 percent of craters, with a false-alarm rate of 12 percent, in Lunar images larger than four pixels acquired by the Clementine spacecraft.
		The program has also been shown to be capable of discovering volcanoes on Venus, sand dunes on Mars, and ice geysers (cryovolcanoes) on Neptune's moon Triton.
		This program was written by Ashley Davies, Eric Mjolsness, Joseph Roden, Michael Burl, Rebecca Castano, Robert Sherwood, Steve Chien, and Timothy Stough of Caltech for NASA's Jet Propulsion Laboratory.

		Preview: Cracks Or Cryovolcanoes Surface Geology Creates Clouds On Titan
		Like the little engine that could, geologic activity on the surface of Saturn's moon Titan-maybe outgassing cracks and perhaps icy cryovolcanoes-is belching puffs of methane gas into the atmosphere of the moon, creating clouds.
		Elevated particle emissions resulting from increased economic activity in Asia may have increased Australia’s tropical rainfall, according to new research on the way pollution influences our climate.

		Atmospheric haze, even clouds can form if the atmospheres are substantial enough.
		Great rift valleys cut across the surfaces, and cryovolcanoes can dot the landscape.
		This activity is powered by a wide variety of factors, ranging from tidal stresses to the slow cooling of their often times small but present metallic cores.

	The case for planet Pluto
		Pluto has an atmosphere, apparently particular to when Pluto is near perihelion, but at which time it drives surface changes: frost deposits form and evaporate over large regions.
		When Pluto is finally examined close up in 2014, astronomers would not be surprised to find similarities to Neptune's moon Triton, which shows geologic activity including active geysers or cryovolcanoes.
		The manner in which the new IAU definition has been implemented is arguably clumsy.

		The book will be called Alien Volcanoes, and comes out through Johns Hopkins University Press late this year.
		I am doing 15 paintings for the book, which covers volcanism on the Moon, terrestrial planets, and Io, then proceeds to the outer system to explore the bizarre cryovolcanoes of Enceladus, Triton, and possibly Titan.
		Regarding new news, I have created eleven illustrations for Dava Sobel to visually express the individual chapters in her new book The Planets.
