Latest Lakes of Titan Stories

A giant cloud half the size of the United States has been imaged on Saturn's moon Titan by the Cassini spacecraft. The cloud may be responsible for the material that fills the lakes discovered last year by Cassini's radar instrument. Cloaked by winter's shadow, this cloud has now come into view as winter turns to spring. The cloud extends down to 60 degrees north latitude, is roughly 2,400 kilometers (1,490 miles) in diameter and engulfs almost the entire north pole of Titan. The new image...

Scientists report definitive evidence of the presence of lakes filled with liquid methane on Saturn's moon Titan in this week's journal Nature cover story. Radar imaging data from a July 22, 2006, flyby provide convincing evidence for large bodies of liquid on Titan today. A new false-color radar view gives a taste of what Cassini saw. Some highlights of the article follow below. Lake Characteristics: -Radar-dark patches are interpreted as lakes based on their very low radar reflectivity...

The tallest mountains ever seen on Titan -- coated with layers of organic material and blanketed by clouds -- have been imaged on Saturn's moon Titan by NASA's Cassini spacecraft. "We see a massive mountain range that kind of reminds me of the Sierra Nevada mountains in the western United States. This mountain range is continuous and is nearly 100 miles long," said Dr. Bob Brown, team leader of the Cassini visual and infrared mapping spectrometer at the University of Arizona, Tucson. During...

Cassini's Visual and Infrared Mapping Spectrometer (VIMS) has detected what appears to be a massive ethane cloud surrounding Titan's north pole. The cloud might be snowing ethane snowflakes into methane lakes below. The cloud may be the clue needed in solving a puzzle that has confounded scientists who so far have seen little evidence of a veil of ethane clouds and surface liquids originally thought extensive enough to cover the entire surface of Titan with a 300-meter-deep ocean. Before the...

WASHINGTON (Reuters) - It has methane rain and white crystalline sand dunes, and now scientists say Saturn's moon Titan also has many lakes. The lakes are probably made up of methane, with a little ethane mixed in, and they are probably the source of the obscuring smog in the frigid moon's atmosphere, researchers reported on Friday. "This is a big deal," said Steve Wall, deputy radar team leader at NASA's Jet Propulsion Laboratory in Pasadena, California. "We've now seen a place...

NASA's Cassini spacecraft has found lakes on Saturn's moon Titan. The lakes are most likely the source of hydrocarbon smog in the frigid moon's atmosphere. Finding the source of the complex soup of hydrocarbons in Titan's atmosphere has been a major goal for the Cassini mission and is a significant accomplishment. Numerous well-defined dark patches resembling lakes are present in radar images of Titan's high latitudes taken during a July 22 flyby. At Titan's frigid temperatures, about minus...

New radar images from NASA's Cassini spacecraft reveal geological features very similar to Earth on an Australia-size, bright region on Saturn´s moon Titan. In one radar strip over 4,500 kilometers (2,796 miles) long, Cassini provided a virtual goldmine, telling the region's complex geological story. Radar images show that the region, named Xanadu, is surrounded by darker terrain, reminiscent of a free-standing landmass. At the western edge of Xanadu, dark sand dunes give...

Arizona -- An international team of planetary scientists may have solved the mystery of why the atmosphere of Saturn's moon, Titan, is rich in methane. Methane, which on Titan plays a role similar to water on Earth, is locked in a methane-rich water ice that forms a crust above an ocean of liquid water mixed with ammonia, the scientists say. Major episodes of outgassing pumped methane into Titan's mostly nitrogen atmosphere three times during the moon's evolutionary history, they...

ESA -- Using recent Cassini, Huygens and Earth-based observations, scientists have been able to create a computer model which explains the formation of several types of ethane and methane clouds on Titan. Clouds have been observed recently on Titan, Saturn's largest moon, through the thick haze, using near-infrared spectroscopy and images of the south pole and temperate regions near 40° South. Recent observations from Earth-based telescopes and the NASA/ESA/ASI Cassini spacecraft are...

Arizona -- Cassini/Huygens scientists have discovered exactly where on Saturn's largest moon, Titan, the European Space Agency's (ESA) Huygens probe landed last January. Knowing the landing location will allow them to directly compare data from Huygens with remote sensing data from NASA's Cassini orbiter. "Based on a truly project-wide collaboration among a number of members of the extended Cassini/Huygens community, we feel we are finally in a position to announce a definitive correlation...
