April Flowers for redOrbit.com - Your Universe Online What resembles a giant hot cross bun? According to radar images from NASA's Cassini spacecraft, a mysterious, nearly circular feature on Saturn's moon Titan does. The report, given at the American Astronomical Society's Division of Planetary Sciences conference suggests that there is also evidence of ancient shorelines. When you bake bread, sometimes the steam causes the top of the bread to lift and crack. The research team believes...

Image 1 - Lake On Titan Resembles One In Africa

A new study based on data from the Cassini spacecraft suggests that a lake on one of Saturn's moons behaves similarly to the Etosha salt pan on Earth. A group led by Thomas Cornet of the Université de Nantes, France, a Cassini associate, found characteristics of Ontario Lake on Titan are similar to Etosha Pan in Namibia, Africa because it drains and refills from below. Etosha Pan is a lake bed that fills with a shallow layer of water from groundwater levels that rise during...

Ontario Lacus, the largest lake in the southern hemisphere of Saturn's moon Titan, turns out to be a perfect exotic vacation spot, provided you can handle the frosty, subzero temperatures and enjoy soaking in liquid hydrocarbon. Several recent papers by scientists working with NASA's Cassini spacecraft describe evidence of beaches for sunbathing in Titan's low light, sheltered bays for mooring boats, and pretty deltas for wading out in the shallows. They also describe seasonal changes in the...

On Earth, lake levels rise and fall with the seasons and with longer-term climate changes, as precipitation, evaporation, and runoff add and remove liquid. Now, for the first time, scientists have found compelling evidence for similar lake-level changes on Saturn's largest moon, Titan"”the only other place in the solar system seen to have a hydrological cycle with standing liquid on the surface. Using data gathered by NASA's Cassini spacecraft over a span of four years, the...

NASA's Cassini Spacecraft has captured the first flash of sunlight reflected off a lake on Saturn's moon Titan, confirming the presence of liquid on the part of the moon dotted with many large, lake-shaped basins. Cassini scientists had been looking for the glint, also known as a specular reflection, since the spacecraft began orbiting Saturn in 2004. But Saturn's northern hemisphere, which has more lakes than the southern hemisphere, has been veiled in winter darkness. The sun only began to...

Titan, Saturn's largest moon, has a huge lake filled with liquid gas, U.S. researchers have confirmed. The lake, called Ontario Lacus, covers about 7,800 square miles at Titan's south pole, and is filled mostly with liquid methane and ethane, say researchers at the University of Arizona's Lunar and Planetary Laboratory in Tucson, Ariz. This is the first observation that really pins down that Titan has a surface lake filled with liquid, said lead researcher Robert Brown. The finding,...

Scientists have confirmed that at least one body in our solar system, other than Earth, has a surface liquid lake. Using an instrument on NASA's Cassini orbiter, they discovered that a lake-like feature in the south polar region of Saturn's moon, Titan, is truly wet. The lake is about 235 kilometers, or 150 miles, long. The visual and infrared mapping spectrometer, or VIMS, an instrument run from The University Arizona, identifies the chemical composition of objects by the way matter reflects...
